On Topology Control of Wireless Peer-to-Peer File Sharing Networks: Energy Efficiency, Fairness and Incentive

Abstract

Given the recent rapidly developing high speed wireless communication technologies and high traffic demand for P2P file sharing applications, wireless P2P file sharing is widely reckoned as a key component of the next generation communication network. However, running P2P applications in a wireless medium entails different constraints compared with those in the traditional wired Internet. One of the challenges is that portable wireless devices are energy-limited since they are battery-operated and the battery has inevitably limited life. Fairness and incentive are also important issues. Unfortunately, designing a protocol taking all these factors into account is still a relatively unexplored problem. We propose a topology control protocol called TCP2P for wireless P2P file sharing networks. TCP2P increases the fairness and provides incentive in wireless P2P file sharing applications and is energy-conserving.
