An adaptive mediation framework for mobile P2P social content sharing

Abstract

Mobile Social Network in Proximity (MSNP) represents a new form of social network in which users are capable of interacting with their surroundings via their mobile devices in public mobile peer-to-peer (MP2P) environments. MSNP brings opportunity to people to meet new friends, share device content, and perform various social activities. However, as the fundamental topology of MSNP is based on public MP2P network, many challenges have arisen. Existing related works restrict the MP2P social network to operate in specific platforms and protocols. Enabling MSNP in a dynamic public MP2P requires a more flexible solution, which can adapt its behaviour to comply with environment. Hence, we propose a mobile device-hosted service-oriented workflow-based mediation framework for MSNP. The fundamental portion of the framework is based on the Enterprise Service Bus architecture which supports changes in runtime resources without the need to re-launch the application. In order to adapt to different situations, our workflow tasks adjust the execution behaviour at runtime. The workflow engine dynamically selects the best approach to complete the mobile user's request based on the cost and performance, calculated by combining fuzzy set and cost performance index. The developed prototype is discussed along with detailed performance. © Springer-Verlag Berlin Heidelberg 2012.
