Abstract

In order to match logical topology to physical topology in P2P wireless network, a new protocol based on Chord is proposed, in which a node can get a optimal node identifier(ID) to realize topology awareness by exploiting nodes' relative location information, which is reflected on the energy strength of received signal and the distribution density of P2P member. Simulation results show that the wireless P2P network in the proposed method can avoid route being accessed iteratively. Therefore, it can effectively shorten the time to locate desired file and reduce Packet Loss Rate as well.
