Abstract

Focusing on the problems that the limited buffer space, and the overhead of transmitting and buffering packets in relay-assisted wireless network, this paper proposed a RTBM scheme. In order to minimize the system overhead during transmission, the RTBM considered multi-stream comprehensive optimization, and used the Markov chain to model and analyze the buffer queue. Combined the the encoding stream rate to increase the coding opportunities, the scheme determined the buffer thresholds of different queues and implemented the coding decision more reasonably. The simulation results show that the scheme can effectively balance the coding opportunities and overheads, and can effectively reduce the delay and improve the network throughput.
