BEB backoff algorithm of IEEE 802.11 DCF mechanism is used usnally because it is easy to be carried out.Due to the limitation of BEB backoff algorithm in DCF mechanism,the network running busily might lead to the delay of transmission and the packets loss rate go up.To deal with the terrible situation,this paper presented a cross-layer backoff algorithm based on DSR routing protocol(CBBD).The new algorithm used the cache of route in DSR routing protocol to solve the problem that the transmission jam at some of the nodes.Simulation proves that the algorithm reduces the transmission delay and packets loss rate largely to improve the performance of the network.
