A topology-aware peer-to-peer protocol applicable to wireless network

Aiming to eliminate the mismatch between structured peer-to-peer (P2P) network´s logical topology and physical topology, which exists in these classic wired P2P protocols, the representative P2P protocol-Chord which is hardly suitable for wireless network is modified, and an approach of getting optimal node identifier (ID) to realize topology awareness is proposed by exploiting nodes´ relative location information. Simulation shows that the wireless P2P network in the proposed method can reduce Packet Loss Rate and minimize the number of hop to locate file effectively.
