Hybrid Multi-Channel Assignment for Heterogonous Wireless Mesh Network

P.Kanaga valli, Mrs.S.Muthu Lakshmi, M.E.,(Ph.D.).,

Wireless mesh networks offer many advantages in terms of connectivity and reliability. Traditionally, Wireless mesh networks based on either purely static or dynamic channel allocation approaches in wireless mesh network. However, there are limitations in wireless mesh networks, such as lower through-put and delay in the channel allocation scheme. This paper is focus on the hybrid multichannel multiradio wireless mesh networking architecture, where each mesh node has both static and dynamic interfaces which efficiently utilizes multiple wireless interfaces to achieve better throughput. Adaptive Dynamic Channel Allocation protocol (ADCA), will considers optimization for both throughput and delay in the channel assignment. Our simulation result show that compared to MMAC, ADCA reduces the packet delay considerably without degrading the throughput.
