| 摘 要： | 该文对IEEE 802.11分布协调功能DCF(Distributed coordination function)进行改进,提出一种实时退避自适应拥塞控制(RBA-CC)协议.RBA-CC协议有两项重要更变:(1)将迅速交换和快速转发机制应用于多跳Ad Hoc网络,减轻了MAC层的流间竞争和流内竞争,从而提高实时业务的传输效率;(2)依据节点的队列瞬间状态确定拥塞状况,让ACK帧携带下一跳节点的拥塞指示信息,以便实现上一跳节点的自适应退避拥塞控制.对RBA-CC协议的仿真结果显示:RBA-CC协议能够降低实时业务数据包的时延,并有效提高网络端到端的饱和吞吐量. |

| Abstract: | This paper improves IEEE 802.11 DCF(Distributed coordination function) and proposes a real-time backoff adaption congestion control(RBA-CC) protocol.The RBA-CC protocol applies Quick-exchange and Fast-forward mechanisms to multi-hop Ad Hoc network.It alleviates MAC layer inter-stream contention and intra-stream contention,and improves the transmission efficiency of real-time traffic.RBA-CC protocol gets congestion information(CI) from queue instantaneous state of node,and then uses ACK frame piggybacking to... |
