Chord is a common circular P2P model with high routing efficiency and stable data inquiring. This paper proposes the Hot-Chord algorithm according to the fact that hot resources have occupied the majority of searching in the P2P system. Hot-Chord algorithm constructs an inner chord dynamically by using the nodes which hot resources is locating, to decrease the inquiring space; Nodes join or leave...
As churn is an inherent character of a network. Researchers find it could bring down the performance of networks. We investigate this in another point of view, and find that searching one resource repeatedly can bring up search efficiency, though churn does bring down the performance for one time search. In this paper, we build a churned peer to peer network in which the connections are re-connected...
In this paper, the performance of peer-to-peer (P2P) file sharing service based-on flooding search algorithm is analyzed. We focus on six types of four-terminal four-router physical network, and investigate the impact of topology inconsistency and flooding search on the file retrieval performance. The analysis model is based on a two-layer queueing network in which both logical and physical topologies...
