A Super Node Selecting Mechanism Based on AHP
Shuling Wang, Shoubao Yang, Kai Shen, Lihua Xie · 2008
In hybrid P2P network, it is needed to select high-performance node as a super node, to provide resource request and routing service for other nodes. The paper considers RTT, interest vector similarity and bandwidth of the node synthetically, and it proposes a super node selecting mechanism based on AHP (analytic hierarchy process). Evaluation shows that this kind of selecting mechanism can decrease 25% average path length of resource searching and 11% usage of the network.
