NEW_CCCA Method For Channel Assignment in Multi Radio Multi Channel Wireless Mesh Networks

Wireless mesh networks have more applications such as Internet access. One of the most famous architectures in these networks, is multi radio multi channel wireless mesh networks. The channel assignment problem is one of the most important issues of our time, which means assigning channels to the interfaces, so that to achieve the maximum efficiency. Offering a solution to the channel assignment should be done to increase the throughput and reduce the interference. In this article we propose NEW_CCCA method and for easier management of channel assignment we use the clustering. The simulation results show that NEW_CCCA improves the performance of the network. It can increase the rate of packet delivery and throughput. In addition, it can reduce the packet loss and average delay.
