Distributed Efficient Channel Allocation Technique for Multi-Radio Multichannel Interference-aware Multi-path Routing Protocol in Wireless Mesh Networks

The major change in the wireless network standards has attracted researchers to utilize benefits of several data services in various applications. Wireless Mesh Networks which follows 802.11 standards are very best alternative to Local Area Networks and Metropolitan Area Networks. There is a need for better utilization of the 802.11 spectrum in Mesh Networks environment when transmitting data through mesh networks. Recent work shows the increase in utilization of 802.11 spectrum for wireless mesh networks. An effort has been made to design and develop a distributed, self healing, self stabilizing protocol that’s assigns channels to mesh nodes in large wireless mesh networks. The efficiency of the protocol is demonstrated with extensive measurements using Qualnet simulator. The distributed channel assignment algorithm improves the capacity of the networks by an average of 25% in comparison to a homogenous channel assignment.
