A Resource Discovery Algorithm in Mobile Peer-to-Peer Based on Vector Location

Low efficiency occurs just because physical topology isn´t considered when Mobile Peer-to-Peer (MP2P) constructs overlay network; this paper will propose a novel vector location-based algorithm based on Distributed Hash Tables (DHT) algorithm. Using pole coordinates to divide physical network into different zones, constructing new routing protocol based on the location vector information; thus, nodes close in physical topology are also close in overlay network. This algorithm can quickly locate resource in large-scale mobile network and experiments demonstrate the efficiency of the algorithm.
