Abstract :
With the maturity of mobile application environment and the popularity of Bluetooth device, researchers focus on data transmission in Bluetooth mobile Peer-to-Peer (MP2P) network. However, QoS of data transmission becomes poor in Bluetooth mobile P2P network because of the limit communicating rate and the mobility of user. In this paper, we propose a novel cross-layer design mechanism, which controls Bluetooth communicating parameterpsilas granularity to reduce impact of packet dropping ratio in MAC layer. Furthermore, a Rateless coding algorithm is used for optimization in application layer to improve network reliability. The results of simulation show that our mechanism can improve network throughput. Moreover, it can reduce the impact of network topology changing and the data transmission distortion.
