Abstract :

Current peer-to-peer (P2P) file sharing methods in mobile ad hoc networks (MANETs) can be classified into two groups: flooding-based, advertisement-based. These two 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. But they fail to adapt the opportunistic nature of disconnected MANETs and also fail to consider the social interests (i.e., contents) of mobile nodes, which can be exploited to improve the file searching efficiency. In this paper, we propose a P2P content-based file sharing system called Social network-based P2P cOntent-based file sharing in disconnected mObile ad hoc Networks (SPOON). The system uses an interest extraction algorithm to derive a node’s interests from its files for content-based file searching. For efficient file searching, SPOON groups common-interest nodes that frequently meet with each other as communities. It takes advantage of node mobility by designating stable nodes, which have the most frequent contact with community members, as community coordinators for intracommunity searching, and highly mobile nodes that visit other communities frequently as community ambassadors for intercommunity searching. An interest-oriented file searching scheme is proposed for high file searching efficiency
