Leveraging Social Networks for P2P Content-Based File Sharing in Disconnected MANETs
Current Peer-To-Peer (P2P) file sharing methods in Mobile Ad hoc NETworks (MANETs) can be classified into three groups: flooding-based, advertisement-based and social contact-based. The first two groups of methods can easily have high overhead and low scalability. They are mainly developed for connected MANETs, in which end-to-end connectivity among nodes is ensured. The third group of methods adapts to the opportunistic nature of disconnected MANETs but fails to consider the social interests (i.e., contents) of mobile nodes, which can be exploited to improve the file searching efficiency. In this paper, the authors propose a P2P content based file sharing system, namely SPOON for disconnected MANETs.
