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
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 transfer the CI to the upper node,realizes adaptive backoff congestion control mechanism.The simulation results show that the RBA-CC protocol can decrease the delay of real-time traffic,and can remarkably increase the network end-to-end saturation throughput.
