Enterprise architecture consists of a set of models describing this technology in different components performance as well as various aspects of the applications in any organization. Therefore, information technology development and maintenance management can perform well within organizations. This study aims to suggest a method to identify different types of services in service-oriented architecture analysis step that applies some previous approaches in an integrated form and, based on the principles of software engineering, to provide a simpler and more transparent approach through the expression of analysis details. Advantages and disadvantages of proposals should be evaluated before the implementation and costs allocation. Evaluation methods can better identify strengths and weaknesses of the current situation apart from selecting appropriate model out of several suggestions, and clarify this technology development solution for organizations in the future. We will be able to simulate data and processes flow within the organization by converting the output of the model to colored Petri nets and evaluate and test it by examining various inputs to enterprise architecture before implemented in terms of reliability and response time. A model of application has been studied for the proposed model and the results can describe and design architecture for data. Growing Science Ltd. All rights reserved. 6 © 201

The available websites on the internet include various topics that some of the websites are working in the field of internet advertising that are usually been created for Internet Marketing. Today, some of these websites for visitors and attract more Internet users are attempted to use false techniques (e.g., by using keywords, etc.). For example, a user by visiting the Google Website searches a sentence. But the question that arises is whether the results of the search are totally associated with the subject user? Perhaps the best answer to this question is No. Because there may be some links presented to the user, unrelated to the topic and these websites just to display their content, insert several keywords related to the searched topic so that the search engines will make mistakes. By considering the above mentioned information, useful searching and accurate results without doubt are the most important demands of Internet users of a search engine. In this article by using genetic algorithm and by considering three parameters of URL Feature, Black list and the number of keywords we will check and analyze these websites. In this study we were able to identify 84% annoying advertisement websites by three parameters.

Article history: Received March 29, 2012 Received in Revised form June, 18, 2012 Accepted 29 July 2012 Available online August 3 2012 Preparing enterprise architecture is complicated procedure, which uses framework as structure regularity and style as the behavior director for controlling complexity. As in architecture behavior, precedence over structure, for better diagnosis of a behavior than other behaviors, there is a need to evaluate the architecture performance. Enterprise architecture cannot be organized without the benefit of the logical structure. Framework provides a logical structure for classifying architectural output. Among the common architectural framework, the C4ISR is one of the most appropriate frameworks because of the methodology of its production and the level of aggregation capability and minor revisions. C4ISR framework, in three views and by using some documents called product, describes the architecture. In this paper, for developing the systems, there are always uncertainties in information systems and we may use new version of UML called FUZZY-UML, which includes structure and behavior of the system. The proposed model of this paper also uses Fuzzy Petri nets to analyze the developed system. © 2012 Growing Science Ltd. All rights reserved.

Mobile ad hoc network is a temporary network that consists of a set of mobile nodes with wireless communication. There are several problems in the relationship between the components of these networks. Some of these problems are related to the routing problem. The main challenge in routing protocols of mobile ad hoc networks is links break phenomenon. This phenomenon has many negative impacts on the performance of routing protocols. In this paper, we attempted to study 10 routing protocols in mobile ad hoc networks that try to improve the performance of standard protocols of this type of network using the Restoration Links Break. By studying the behavior of these protocols, a common model used by all these protocols was introduced as Restoration Links Break model. Then the performance of each of the protocols was described based on the proposed model. On the other hand, we divided them into two categories according to protocol functions in Restoration Links Break. First category provides alternate routes before the Links Break event and the second category performs the replacement of route after the links break. Finally, the simulation of results revealed that the first category of protocols has a better delivery rate than the second category but the routing overhead of the second category is less than the first category.

Wireless sensor networks (WSNs) are consist of hundreds or thousands small nodes called sensors that are connected to each other to do specific tasks. Routing is one of the main operations that nodes are doing in WSN network. Routing consist of selecting the next node by each node in the WSN. A variety of methods is proposed for routing. But in the field of using fuzzy logic approach for flat routing has rarely been studied. Since more than one parameter is considered in selecting the next node, using fuzzy logic will be useful. Our proposed method is a fully distributed method and all operations are done by the nodes. Use of fuzzy logic increases speed, accuracy and power of the routing. Also since the processes are completely local, this structure is very useful for environments that require real-time processing. Evaluations show that our method dramatically increases the network lifetime.
