Extended Node Management Policy for Integrated P2P Network Services

摘要

Wireless network services for mobile terminals are actively underway. Therefore, the necessity to effectively provide the existing wired network-based P2P services in wired/wireless based integrated network environments is coming to the fore. However, since the mobile terminals that use wireless networks are characterized by the utilization of available resources, limited battery capacity, limitations of storage devices, and free mobility of terminals, their peer-to-peer connections are frequently disconnected and, consequently, their network configuration is drastically changed. Therefore, the wired network based peer scheduling policy is not suitable for wired/wireless integrated networks. To that end, in the present paper, an extended P2P peer management policy is proposed considering the characteristics of the terminals that receive P2P services on integrated networks. This policy is composed of a Degree Ordered Strategy and a Mobile P2P Service Strategy and shows the performance improved by ca. 25% or more as compared to the existing wired node-based TOT and BOT methods or the RJS method, which is specialized for mobile nodes in terms of the degree reconstruction for network recovery and service delay.
