On the Implementation Problems of Mobile Peer-to-Peer Networks

Since peer-to-peer (P2P) systems are dominating in Internet traffic, there were several attempts to implement it in mobile wireless networks, in particular in GSM/GPRS and UMTS networks. In this work basic and hidden problems which prevent it from successful implementation are studied as well as some proposals and improvements are presented. Mainly this work is focused on specific features of mobile wireless networks which make current fixed network solutions inefficient or even inadequate using GPRS or UMTS networks as a transport channel. As a result, bandwidth-efficient and totally adapted to wireless ldquonaturerdquo of mobile networks torrent protocol (wp2p) for mobile users has been developed and proposed.
