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.- Dynamic Channel Allocation Technique for Distributed Multi-radio Multichannel Multi-Path Routing Protocol in Wireless Mesh Networks

Wireless Mesh Networks (WMNs) have gained main attraction in providing flexible network services and support to the end users. There are many efforts seen to design robust routing protocol for WMNs and solutions are proposed to standardized channel allocation techniques. There are various approaches dedicated to maximize the network though put and minimize network interface. Existing multi radio multi channel routing protocols utilize only single channel situation and static channel allocation degrades the performance of the WMNs. The challenge is to allocate channel without link interference and to improve end-to-end throughput efficiency in multipath routing for WMNs. In this paper, we propose a dynamic channel allocation technique is proposed for multi path routing protocol for WMNs. Dynamic channel allocation is used to avoid the inter-flow and intra-flow channel competition and interference. The protocol establishes and maintains multiple channel dimensional disjoint points changing frequently and each data flow is separated into multiple paths. NS2 simulations are carried out for the evaluation of the performance of the proposed channel allocation technique and compared with popular routing protocols of Mesh Networks Ad hoc On Demand Distance Vector Routing Protocol (AODV) and Hybrid Wireless Mesh Protocol (HWMP). The simulation results show that proposed dynamic channel allocation technique achieve better adaptability with less overhead and interference. The multipath routing show increase end-to-end throughput significantly.Keywords
