BlueTorrent-ED:a Rateless Coding-used Bluetooth Protocol in Mobile Peer-to-Peer Networks
Feng Zeng · Journal of Chinese Computer Systems · 2009
Now,Mobile Peer-to-Peer(P2P) network becomes extensive focus of researchers. The popularity of Bluetooth intelligent terminals and the maturity of mobile application environment bring practical significance and bright prospect for mobile Bluetooth P2P networks. However,there are new challenges caused by the limit bandwidth,short communication range in mobile Bluetooth P2P networks. In this paper,we investigate the ways of selection of Bluetooth communicating parameter and data dissemination strategy. A new Bluetooth protocol is proposed. It is improved upon Bluetorrent,referred as Bluetorrent-ED. Bluetorrent-ED controls Bluetooth back off time's granularity to reduce network connection delay. Furthermore,To improve network's reliability,On-Line coding algorithm is used for optimization in data dissemination. The results of simulation show that Bluetorrent-ED can reduce the impact of network topology changing and the ratio of packet loss. Furthermore,it can improve network throughput.
