摘要 针对分布式无线网络提出了一种支持语音/数据业务的多信道媒体接入控制协议.该协议基于竞争的CSMA/CA机制,具有动态的信道分配并且信道数目不依赖于网络拓扑结构的特点.协议改进了IEEE802.11标准中的退避算法,并采用不同的帧间隔以保证实时语音业务的性能. The design and performance of a multichannel MAC protocol for voice/data integrated traffic over IEEE 80211 mobile adhoc networks are presented. The proposed protocol is based on CSMA/CA basis. The dynamic channel selection scheme is implemented and the number of the data channel is independent of the network topology. The priority for realtime traffic is assured by improving back off arithmetic and different IFS.
