Quality of Service Aware Dynamic Channel Allocation for Multichannel Multi Radio Wirelessmesh Network

Multichannel multi radio wireless mesh networking is an emerging technology that can support numerous multimedia applications. Efficient channel assignment is essential in Multichannel multi radio wireless mesh network deployments to support QoS requirements, i.e., delay bandwidth, throughput and packet loss ratio to enable such QoS-demanding multimedia applications. This paper proposes QoS aware Dynamic Channel Allocation (QSDCA) algorithmwith the objective of providing an optimized performance over meshnetwork. The algorithm considers the available bandwidth at each node, waiting time of the end user and the service time of the servicing node to avoid co channel interference. The performance of the proposed algorithm has been evaluated using the metrics such asthroughput, channel access probability and delay. The result shows that the network performance has been improved when compared to the existing channel allocation schemes.
