Coordinated Distributed Scheduling Algorithm Based on QoS in Wireless Mesh Networks
Liping Liu · Journal of Chinese Computer Systems · 2011
Wireless Mesh Networks is one of the most important next-generation broadband wireless communication technologies;it has more and more attention.For the deficiencies of existing scheduling algorithms,the paper proposes a coordinated distributed scheduling algorithm based on QoS in TDMA——CDS-QoS(Coordinated Distributed Scheduling-Quality of Service).Its core is when the node has a transmission opportunity,it needs to predict and tell others its next transmission time.The mechanism schedules differently for different flows,so that it can guarantee the node′s QoS.Simulation shows that the algorithm has high efficiency,and can ensure the QoS of different multimedia services.
