无线Mesh网作为下一代宽带无线通信网络的关键技术之一受到越来越多的关注.针对现有无线Mesh网MAC层调度算法的不足,提出一种基于TDMA模式的支持QoS的协同分布式调度算法(CDS-QoS:Coord inated Distributed Schedu ling-Quality of Service).算法的核心思想是在本次发送控制消息的同时预测下一次发送的时机,并告知其他节点,在预测的同时保证节点的QoS,对不同业务流进行有区分的调度.实验结果表明,CDS-QoS算法具有较高的时效性,并且能够有效保证不同多媒体业务的QoS.
As one of the key technologies of the next generation of broadband wireless communication networks, the wireless Mesh network is receiving more and more attention.Aiming at the shortage of the existing MAC layer scheduling algorithm of wireless Mesh network, a TDMA-based cooperative distributed scheduling (CDS-QoS): The core idea of the algorithm is to predict the timing of the next transmission while sending the control message and inform other nodes of the QoS of the node , And carries on the differentiated dispatching to different business flows.Experimental results show that the CDS-QoS algorithm has higher timeliness, and can effectively guarantee the QoS of different multimedia services.
