Distributed Sender Scheduling for Multimedia Transmission in Wireless Mobile Peer-to-Peer Networks

Multi-source multimedia transmission is a popular architecture in wireless mobile peer-to-peer (P2P) networks. Most of previous work on wireless mobile P2P networks concentrates on the protocols and network structures, and consequently ignores the multiple senders scheduling problem. In this paper, we present a distributed algorithm for scheduling the multiple senders for multi-source transmission in wireless mobile P2P networks, which can maximize the data rate and minimize the power consumption. Specifically, we formulate the wireless mobile P2P network as a multi-armed bandit system. The optimal distributed sender scheduling policy can be found according to the Gittins indices of the senders. Extensive simulation examples illustrate the effectiveness of the proposed scheme. It is shown that the data rate and power consumption in the proposed scheme can be improved significantly compared to existing schemes.
