In unstructured peer-to-peer network,we need to find hubs to restrain＂free-riding＂behavior.In this paper,based on referring previous connection numbers from hubs,we took nodes＇power difference into account,also introduced the concept about load degree and those nodes holding high load degree are called overload nodes.Then a load balance control algorithm was proposed,in which load from overload nodes is shifted to light-load nodes.Simulation results shows the algorithm can effectively balancing nodes＇load and load distribution is more balan...
