Super node selection based on dynamic processing power of CPU in peer-to-peer networks
Kaigui Wu · Computer Engineering and Applications Journal · 2011
In unstructured P2P,the ordinary nodes select a super node by considering synthetically multiple factors such as distance cost,credibility,content similarity,the dynamic processing power of CPU and etc.And the dynamic processing power of CPU exerts the most important factor in all undoubtedly.This paper presents a new approach aiming at how to choose a super node.It predicts the dynamic load of CPU using a Radial Basis Function(RBF) neural network,assesses the dynamic processing power of super node’s CPU by the dynamic loading of CPU and provides the information for ordinary nodes, which helps ordinary select a most suitable super node.Though analysis and simulation experience results indicate that this approach can improve performance of the whole system efficiently,system cost reduction of 96% or more.
