Research on NICE Protocol Based on User Behavior Analysis
Application layer multicast(ALM) which uses end hosts to relay data has a prosperous prospect in media server.But data delivery in ALM tree can be easily interrupted by departure of end hosts in P2P network,which may lead to degradation of QoS in time-sensitive applications such as live streaming.This paper proposes a new cluster-leader selected algorithm based on the analysis of end hosts' stability and capabilities.When compared with NICE protocol via simulation,the enhanced protocol provides lower end-to-end delay and higher robustness.
