Distributed Spanner Base Channel Assignment in Wireless Mesh Network

A wireless mesh networks (WMNs) has emerged recently WMN consist of two types of nodes mesh routers and mesh clients.WMN is dynamically self-organized and self-configured with the nodes in the network automatically establishing and maintaining mesh connectivity among themselves. Channel assignment is a critical issue in WMN which is the mapping between the available channels and the radios at each node such that the network performance is optimized and hence the focus of this work along with static channel assignment multi-radio multi-channel. Multi-radio MAC can potentially achieve higher network capacity than single-radio MAC. We design and implement a new agent (DSBCA) distributed channel assignment spanner base the routing protocol Optimize the network performance considering the throughput end-to-end delay connectivity and the interference of our channel assignment algorithm. Base on the network simulations NS2.34 on Linux Fedora and our proposed channel assignment algorithm improved the throughput minimal-connectivity preserving channel assignment algorithm.
