472. A situation aware information infrastructure (SAI2) framework

Author

Abstract

Computer network infrastructures constitute the critical backbone of every socio-economic ICT system. Consequently, they are becoming increasingly mission-critical in our society since they provide always-on services for many everyday applications (e.g., Cloud Data Centres), safety-critical operations (e.g., Air Traffic Control networks), critical manufacturing services (e.g., Utility networks and Industrial Control Systems), and critical real-time services (e.g., Financial Trading Systems). The resilience and ability of such systems to remain operational in the face of threats is therefore paramount; this needs to be done by taking remedial action and intelligently reshaping their resources. At the same time, current communication architectures do not allow for such informed and adaptive provisioning. In this paper, we introduce the concepts, principles and current research activities related to a new Situation Aware Information Infrastructure (SAI2) framework being developed for next generation ICT environments.

Abstract

Applications supporting the independent living of people with disabilities are usually built in a monolithic fashion for a specific purpose. On the other hand, a crucial sector for the livability of urban spaces such as mobility is undergoing a deep transformation, heading towards flexible composition of standardized services. This paper shows how this approach allows to build better applications for people with specific needs, making them seamlessly integrated in the most modern approach to smart mobility.

Abstract

The wide diffusion of Online Social Networks (OSNs) presents several advantages, like the definition of simple tools for information sharing and spreading. However, OSNs present also some drawbacks, one of the most important one is the problem of privacy disclosures. Distributed Online Social Networks (DOSNs), which decentralize the control of the social network, have been recently proposed to overcome these issues. The decentralization of the control has issued several challenges, one of the main ones is guaranteeing data availability without relying on a central server. To define users’ data allocation strategies, the knowledge of the structure of the ego network and of the user’ temporal behaviour is required. Unfortunately, the lack of real datasets limits the research in this field. The goal of this paper is the study of the behaviour of users in a real social network in order to define proper strategies to allocate the users’ data on the DOSN nodes. In particular, we present an analysis of the temporal affinity and of the social communities based on a real Facebook dataset.

Abstract

Many researchers have nowadays shown a paramount interest in the rising field of Mobile Crowdsensing (MCS). Such paradigm is considered an easy and cost-effective choice for observing phenomena of common interest within the scope of Smart Cities and environmental monitoring. Nevertheless, it brings along many issues, such as fostering participation, reducing the power consumption of end devices and granting coverage. In this paper we focus on the problem of data collection control, which aims to avoid data redundancy and useless power consuming data transfers while assuring a sufficient number of observations for the purpose of coverage. In particular, we design a probabilistic distributed algorithm that aims to achieve a total per-zone number of observations close to a defined amount, while maximizing the fairness among users. We provide both the analytical definition of our algorithm and the performance evaluation through extensive simulations, establishing our algorithm as a good baseline for a poorly investigated problem.

Abstract

In recent years, the growing prevalence of social networks makes it possible to utilize human users as sensors to inspect city environment and human activities. Consequently, valuable insights can be gained by applying data mining techniques to the data generated through social networks. In this work, a practical approach to combine data mining techniques with statistical analysis is proposed to implement crowd sensing in a smart city. A case study to analyze the relationship between weather conditions and traffic congestion in Beijing based on tweets posted on Sina Weibo platform is presented to demonstrate the proposed approach. Following the steps of raw dataset pre-processing, target dataset processing and statistical data analysis, analytic corpus containing tweets related to different weather conditions, traffic congestion and human outdoor activity is selected to test causal relationships by Granger Causality Test. The mediation analysis is also implemented to verify human outdoor activity as a mediator variable significantly carrying the influence of good weather to traffic congestion. The result demonstrates that outdoor activity serves as a mediator transmitting the effect of good weather on traffic congestion.
