MMS: Multi-rate Multicast Scheduling in Multi-radio Single-cell CR-WMNs
AbstractNowadays, cognitive radio technology is mentioned as a new model for wireless communication. In this paper, by extending the previous works, both multi-radio and multi-rate technologies in single-cell multi-channel cognitive radio wireless mesh networks were adopted. In this regard, an efficient scheduling algorithm is introduced named Multi-Rate Multicast Scheduling (MMS). Multi-radio technology allows the nodes to simultaneously send/receive packets on the distinct channels. Consequently, the network throughput will be increased. Furthermore, since different transmission rates lead to different spectrum utilizations, efficient use of the multi-rate capability can improve the performance of the network. Numerical results of our comprehensive simulations confirm the efficiency of the MMS algorithm.
