Abstract

Compared to Client/Server architecture, P2P architecture has the advantages of service availability, self-organization, and fault tolerance. However, the topology mismatching problem between logical P2P overlay network and underlying physical IP network has resulted in performance degradation of P2P network due to the randomly joining and leaving of peers, causing a large volume of redundant messages in the Internet. This situation is even more severe in wireless mobile P2P network. This study proposes a location-aware wireless mobile (LAWM) P2P architecture which adds the locality support for peers in order to alleviate the topology mismatching problem. LAWM employs a two-tier architecture where the upper tier is a Chord overlay network composed of super-peers, grouping nearby peers according to their location information, and the lower tier composed of clusters of peers, connecting to the physically closest super-peers. Simulation results show that the proposed LAWM architecture not only solves the topology mismatching problem but also significantly reduces the average neighbor's response time. Furthermore, the impact of the total number of peers, peer mobility ratio, and cluster size on performance is also demonstrated.
