Attribute Based Content Sharing in Mobile Adhoc Networks of Smartphones over WiFi

Mobile phones are increasingly equipped with features that allow them to generate, store, and make use of a large amount of digital content. Such content can be associated with attributes obtained via context and/or user annotation. With the increased trend of information sharing and the success of peer-to-peer (P2P) in the wired world, the ability for users to search and share content on their mobile devices is engaging. However, infrastructure-based networks may not always be available or affordable, and attribute- based content sharing in mobile adhoc networks is desirable. This paper investigates the feasibility of such solutions and proposes a system design that incorporates efficient content discovery, robust content distribution, and adaptive energy management techniques. Detailed performance evaluation of a prototype system demonstrates that attribute-based content sharing can be effectively supported in mobile adhoc networks of smartphones over WiFi.
