In this paper, we design and implement a mobile game based on windows phone platform. Visual Studio and the Windows Mobile software development kit(SDK) and developer tool kits (DTK) make it possible to create software for the Windows Mobile platform in Visual C#. Also The XNA Framework is the set of .NET libraries that developers will code against to build games. XNA Framework support PC and XBOX and a ZUNE HD multiplex platform environment and 2D and 3D games provides the necessary functions to a development. XNA Framework is to make it easier to develop games because the codes which are succeeded creates with automatic, implements a game development relation resource and the game logic. The key idea of our game is that we use shooting and ranking system to raise fun.

For the small-scale and scattered fresh cucumber production in China, the result that production record-keeping and its transfer are inefficient have prevented the wide application of traceability systems in China. With the mobility and computability, Personal Digital Assistant (PDA) provides a new way for agricultural information collection to solve the above problems. Thus a PDA-based Record-keeping and Decision-support System (PRDS) for traceability in cucumber production was developed on Windows Mobile platform invoking a Geographic Information System (GIS) control. For improving the decision making feasibility of PRDS, the fertilization recommendation model and pesticide usage early warning model were developed by using the Technical Specification of Balanced Fertilization by Soil Testing and the Guideline for Safety Application of Pesticides in China. The architecture of PRDS was provided. With Unified Modeling Language (UML), a requirement model including two types of users and 17 use cases was described, and a static class model was also designed, which consisted of table class, table operation class, algorithm class and interface class. Based on these models, the functions of system setup, map management, data management, production record-keeping and decision-support and query, etc., were implemented by adopting Hosting MapInfo MapX Mobile Controls on the .NET Compact Framework 2.0, and the data synchronization was realized by Remote Data Access (RDA). Two agricultural production enterprises were chosen as case study to evaluate the system by questionnaires. The results show that the efficiency of production record-keeping and decision-support is improved by the simple and friendly system.

The article describes some possibilities for developing mobile devices’ extents for system MES (Manufacture Execution Systems) Xfactory. A fundamental idea is based on .NET, .NET Compact framework and web services. Application is able to communicate with Xfactory in two directions: into the Xfactory – as a data source (from manufactory to planning) or from Xfactory – as a consumer (data about manufacture's steps, etc.). As a mobile’s device is used PDA with WiFi net (802.11b).

Many standard baby-tests (paper and pencil versions) are used in clinics to evaluate by separate major domains in child neurodevelopment (ND) such as: 1) speech and language, 2) motor and 3) sensory (visual and hearing). Our aim was to design an automated easy to apply instrument that integrates in one test important milestones in all these domains. The test to assess pediatric neurodevelopment (NPED in Spanish) was implemented as software upon a mobile device personal digital assistant (PDA). It allows a rapid standardized (age adjusted) evaluation of language and psycho motor development and includes original hearing and visual acuity tests. The NPED system detects neurodevelopmental deviations in these areas providing a final PASS/FAIL result. The software was implemented, using the integrated development environment Visual Studio 2008, Visual C# programming language, and the .Net Compact Framework. Test results are stored in a PDA database and can be exported to a desktop PC for further analysis. Also, the test items and materials can be easily configured to the PDA features and can be adapted to different cultural environments (language items). Although the system as all screening tools was designed to identify ND disorders that should be referred for diagnosis, it gives also useful information for management and intervention of children with slight ND problems. Thus it could be implemented as hand- held automated screening tool at primary care health services to be used by volunteers and/or other personnel with minimal training.

This month we’re embedding ourselves inside Microsoft’s .NET Compact Framework (CF), billed by Microsoft as the perfect platform to create software applications that target mobile devices. That’s accurate—and it’s not.

Human life is divided into day periods as a main periods which consist of a day and night phase. Most of humans need to sleep a eight hours in a minimum to have their body and all the body function ready in day phase of a day. The second very important thing (instead of 8 hour sleep) is a phase of sleep in which a human is wake up. Waking up of a human in deep sleep phase lead to a very “unhappy” morning and not so nice spend of day. We are trying to develop algorithms to detect mild sleep stages which are the most suitable to human wake up. Actually we use microphone input to record and process sound near the monitored user. All the knowledge is implemented to mobile phone (windows mobile based device) as an intelligent alarm application. Whole application is designed as multithread Real-Time application based on. NET Compact Framework platform in C# language. Filtration and detection algorithms used special Math library Math. NET to process a recorded sound signal. This paper consists of several chapters which describes design, implementation and testing phases of this mobile application development. Actual testing results shows that our developed application detect correctly more than 70 % of mild sleep stages of all tested persons.

New robot applications using smart devices are recently providing interesting and feasible solutions to longstanding problems. In this study, we propose a remote control and monitoring method using an omni-directional mobile robot with a smart device. We also developed remote control and monitoring application software for the smart device by using Microsoft’s .Net Compact Framework and Bluetooth data communication to support various smart OS Platforms. We evaluated the feasibility and the effectiveness of the proposed method by conducting several experiments involving remote control of a mobile robot using a gravity sensor in a smart device and remote monitoring.

Mobile devices are now used not only for communication but also as working units. As more sensitive information is stored on and transmitted through these devices, security is becoming a growing concern. This is especially true for SMS messages which do not integrate any security mechanism. This is why we propose a simple-to-use but cryptographically strong API for message encryption and authentication that was designed with the limited memory and processing power of a mobile device in mind; and a protocol that will ensure their confidentiality and integrity. This strategy is embodied in the cryptography framework called Linca and the SMS security protocol called SMSSec. The framework and protocol are tested through the design and implementation of an SMS banking application called SecureBanking. The application was written for the .NET Compact Framework (.NET for mobile devices) and was based on a previous version done for Java 2 Micro Edition (J2ME). Finally, a performance analysis is presented to show that the encryption time on the mobile device is negligible compared to the duration of the transmission.

Handheld devices in a pervasive computing environment are prone to security as well as privacy violations, while discovering, sharing and accessing services and contents. Trust models are devised to fight against such violations and breaches. Although initial trust assignment is an important issue in evolving overall trust, a little amount of work has been done in this field so far. In pervasive smart space, similar type of contexts exhibits significant correlations to each other. However, this fact is not taken into consideration while computing the initial trust values. In this paper, we describe a new mechanism to assign initial trust: CCTB (Context Correlation for Trust Bootstrapping), which takes advantage of the presence of correlations among different contexts in a context-ontology. We evaluate the effectiveness of CCTB by simulating in two different scenarios. We show that CCTB offers better initial trust values than the other models considered here. We also implement a prototype for performance measurement using .NET Compact Framework.

This paper conveys some of the experiences with using commercial off-the-shel (COTS) products as clients to Bluetooth enabled devices, which have no user interface of their own, but relies on the COTS products for user interaction. The COTS devices used include several different vendors' models of the microsoft Pocket PC platform (also known as windows mobile professional or classic) running .NET compact framework, as well as a number of different models of Java enabled cell phones from nokia, siemens and sony-ericsson. The specific case study is with the Taxmaster4 Windows mobile product used with BMW automobiles as a driving log application. The paper concludes that many usability problems exist when using COTS products. These may to some extend be overcome by pragmatic design decisions, but it is necessary that the COTS products hardware platform and application programming interfaces should become better suited to support distributed user interfaces than is the case today. This includes better support for basic user interface elements as well as supporting Bluetooth and other wireless technologies more reliably. These issues should be addressed by the vendors and manufactures of these platforms, not the application programmers.

The application is developed for Romanian language but there is also provided necessary building blocks and interfaces to help other developers extend the platform for their own language and culture.

This project deals with the problems of utilization of mobile equipment working in the biomedicine field, particularly telemedicine. This field is relatively new; it focuses on the observation of life functions from a distance. Practically developing system works with an ECG sensor connected to mobile equipment, such as PDA/Embedded device, based on Microsoft Windows CE class operating system. The whole system is based on the architecture of .NET Compact Framework, and other products, such as SQL Server by Microsoft too. This work also deals with the communication of mobile equipment with sensors and with the server via Bluetooth, WiFi, and GPRS/EDGE. The mobile equipments are used primarily for measuring and processing of data from the sensors and their visualization as a graph. The data is also given to the server for further processing and the analysis of current health of the patients, due to small efficiency of the mobile equipment. The main task we deal with in the server part of application is receiving of the data via web services and further processing, management and analysis of this data. For the analysis of received data and further evaluation of the electrocardiogram, there is a self-organizing neural network [1].

This research investigates the threat .NET viruses pose to mobile devices supporting the .NET Compact Framework. The focus is on (1) the feasibility of transforming, via renovation, a .NET virus to comply with the .NET Compact Framework and (2) deciding if the transformed virus can succeed in infecting a mobile device supporting the .NET Compact Framework. A formal model to identify non .NET CF compliant source code and to derive transformation rules is presented and characterized. The model was used to transform a test suite of .NET viruses to comply with the .NET Compact Framework. These transformed viruses successfully infected files on two mobile devices. Four desktop virus detectors were tested to detect the .NET viruses and their transformed versions. Three of the four did worse in detecting the transformed versions than on the original .NET version. The research shows that .NET viruses pose an apparent and realizable threat to mobile devices supporting the .NET Compact Framework.

Platform independence is the major advantage of the Java programming language. Whereas Java is widespread on servers, desktop computers and mobile phones. In contrast, PDA and Pocket PC applications are usually based on C or C# applications in the .NET Compact Framework. The paper focuses on the J2ME standard and its suitability for Pocket PCs and PDA. In that context we also give an overview of existing Java Virtual Machines (JVMs). In particular we evaluate Esmertecs Jbed CDC, IBM Websphere Everyplace, Creme and MySaifu and compare them according to functional criteria as well as standard conformance and performance. Furthermore a set of tests to benchmark these different JVMs is given. Finally, An example application is implemented, as part of the Bosporus project, to evaluate the JVMs from the programmers perspective.

In this paper we compare the Java 2 Micro Edition and the .NET Compact Framework with respect to their performance for programming multiplayer games for PDAs. We benchmark results for both platforms dealing with computational capabilities and communication performance over WLAN. We also have developed a simple prototypical multiplayer game called 3D-Pong and evaluate how simple resilience mechanisms can hide WLAN packet losses for this game.

A new class of m-commerce applications is emerging due to the unique features of handheld devices, such as mobility, personalization and location-awareness. We present SMMART, a context-aware, adaptive and personalized m-commerce application designed to deliver targeted promotions to the users of mobile wireless devices. Promotions distributed by SMMART are personalized by matching the user's shopping interests to current promotions available at a retail site. SMMART adapts to changing interests of its user by monitoring his or her shopping habits. We describe a fully functional prototype of SMMART built for Pocket PCs running Windows CE with .NET Compact Framework. The main focus of the proposed demonstration is on the aspects of the user interaction with SMMART and its diverse features.

Software development for mobile devices is relative new and has its own challenges, especially when developing a single application that will run on either a PDA or a notebook PC. This work describes the development of a sales system for use by a salesperson in the field. Windows-based devices and Microsoft development tools were used to implement the application for the .NET Framework for the notebook PC and the .NET Compact Framework for the PDA. (One might run into a totally different set of issues attempting to do this with Java and J2ME). Developing a common code base for classes was relative easy, but was difficult for the user interface. Issues faced and lessons learned during the application development are outlined in this work. The application software architecture, hardware, database, and connectivity are also described.

Today, handheld devices play an important role in human's life. Pocket PCs, Palms and Mobile devices are good examples of handhelds; one of the main concerns when we use these devices is how the interface in these devices works and what characteristics are important in creating a good User Interface. This paper describes a brief study on needs for a User Interface in handheld devices and then we will compare and explores the needs for creating the most efficient User Interface in these devices. Different factors such as application, platform and device in the context of .NET Compact Framework and J2ME were described for developing a good interface in this paper. .NET Compact Framework and J2ME are platforms for development of applications for smart devices. Here we overview these two leading platforms for smart device development. We discuss and do a comparative analysis of these two technologies by means of developing a 'Math Tutoring Game' in both the environments.

As Web service technology evolves, the idea of context-aware services gains more interest. An idea is that different sets of services will dynamically drop into the mobile users' devices depending on their contexts. To do this effectively requires location modelling and representation as well as spontaneity in downloading and executing the service interface on a mobile device. This paper introduces the concept and an implementation of hanging services that supports proactive and ad hoc context-aware services in mobile environments. This system works on top of an 802.11b wireless network. The prototype implementation is done using Web services and highly compact mobile code applications using Microsoft .NET compact framework.

The compact, mobile device, such as the PocketPC, is often regarded as little more than a handy, smaller "portal" by which to access information kept on larger back-end machines such as exchange servers and WWW servers. However, the true value of the device may ultimately result from more sophisticated approaches by which the device can fully recognize and change its behavior based on its context, such as location, remaining battery life, available networking, and user preferences. We present "UVa Bus.NET", a testbed at the University of Virginia for developing and evaluating general, context-aware, mobile solutions. We use .NET, .NET Compact Framework, GPS-enabled devices, and wireless networking inside buildings to notify students and professors of impending appointments and class meetings, give directions to their next appointment, and even direct them to the real-time location of the most appropriate bus to catch. The longer-term goals of UVa Bus.NET are also presented: to provide a more predictable experience to mobile device users by hiding and otherwise managing resource limitations.

The goal of the GecGo middleware is to provide all the services required by self-organizing distributed applications running on multihop ad-hoc networks. Because of the frequent as well as unreliable and anonymous communication between accidental neighbors observed in these networks, applications have to adapt continuously to changes in the mobile environment and the GecGo middleware offers the required tight coupling. Additionally, GecGo addresses specifically the issue of en passant communication, where moving neighbor devices may interact only for short periods of time. In this paper, the architecture and basic concepts of the GecGo middleware are discussed and a prototype implementation of GecGo using the Microsoft Windows CE 4.2 .NET operating system for mobile devices and the .NET Compact Framework is presented. The paper also addresses issues on application programming and example application prototypes for these mobile networks.

This is the final report for the Ad Hoc Human Interaction Nets project. All tasks described in our original proposal have been completed: Hybrid-Hierarchical Micro-Databases, Query Optimization, and XML for Embedded Systems. After meeting with the program manager, Tom Armour, in Washington, DC, we were able to get a better perspective on the ad hoc nature of the solicitation. Armed with this perspective, we were able to complete two substantial prototypes to address the four tasks as originally written that works with Pocket PC and Palm OS devices. We were able to evaluate the viability of the Sharp Zaurus platform as well but ultimately decided to limit our focus to Palm OS and Pocket PC devices, which appear to have the greatest market interest and viability at the time of writing. Acquiring the hardware enabled us to make substantial progress on the ad hoc networking issues. In our networking prototype, which is based on the Pocket PC platform, we were able to take advantage of the emerging. Net compact framework and use it to build a distributed services and database framework. In this report, we will describe the two concept prototypes that were developed to demonstrate the feasibility of ad hoc human interaction networks and then proceed with a brief discussion of each task as written in the original proposal.

This paper presents our experiences in porting selected parts of the .NET Compact Framework to Symbian smartphones. Our port includes support for basic services such as threading and file access, low-level networking modules as well as Web Services. We also present a portable .NET GUI for the Symbian platform. The paper shows how the programming models of .NET can be efficiently mapped to the runtime structures provided by operating systems for resource-constrained devices such as the Symbian OS. In a detailed analysis, we compare the performance of our port to that of Java and native code.

The .NET Compact Framework is designed to be a high-performance virtual machine for mobile and embedded devices that operate on Windows CE (version 4.1 and later). It achieves fast execution time by compiling methods dynamically instead of using interpretation. Once compiled, these methods are stored in a portion of the heap called the code cache and can be quickly reused to satisfy future method calls. While the code cache provides a high-level of reusability, it can also use a large amount of memory. As a result, the Compact Framework provides a “code pitching” mechanism that can be used to discard the previously compiled methods as needed. In this paper, we study the effect of code pitching on the overall performance and memory utilization of .NET applications. We conduct our experiments using Microsoft’s Shared-Source Common Language Infrastructure (SSCLI). We profile the access behavior of the compiled methods. We also experiment with various code cache configurations to perform pitching. We find that programs can operate efficiently with a small code cache without incurring substantial recompilation and execution overheads.

Present-day museums are not mere passive institutions for the preservation of a society's cultural heritage. They have become instead learning environments, research centres and even tourist attractions. The paper introduces the notion of a hybrid museum (HM) in which wireless personal digital devices (PDAs) are used to tailor digital contents to the visitor to enrich both the learning and entertainment experience. The paper describes a fully functional hybrid museum infrastructure (MoMo) implemented with the.NET compact framework running on the PocketPC platform. Several research challenges that had to be faced during the implementation of the system such as the exploration of large sets of information on PDAs are also presented; and the customisation and personalisation of the displayed contents using a modified partial prediction matching algorithm are also discussed.

The following paper describes a distributed application for collecting data from mobile devices. The solution is collecting data through mobile device PDA and then sending them to central server accumulating and processing data. An example of such a system is an application that collects data from GPS receivers located in cars. The authors based their solution on that type of a system. The programs were written with the use of the C# language and .NET Framework platform version 1.1 as well as the mobile version NET Compact Framework 1.0. The result of the presented work is an advanced system that fulfils commercial standards
