WNChord: A Weighted Nodes Based Peer-to-Peer Routing Algorithm

Considering the existing difference in load rates, computing performance and delivery latency between peers in Chord protocol, we present a weighted nodes based P2P routing algorithm(WNChord), in which each node could be treated respectively to make highly capable nodes take more tasks. Specifically speaking, the routing algorithm in peers is reformulated and is parameterized using a quantity C, which may control latency’s expected value such that P2P network’s total latency to become much lower by choosing proper C.
