An Efficient Bandwidth Estimation Schemes used in Wireless Mesh Networks

wireless mesh networks (WMNs) has been widely used for the new generation wireless network. The capability of selforganization in WMNs reduces the complexity of wireless network deployment and maintenance. So, the perfect estimation of the bandwidth available of the mesh nodes is the required to admission control mechanism which provides QOs confirmation in wireless mesh networks. The bandwidth estimation of schemes do not give clear output. Here we are proposing bandwidth scheme estimation for decreasing the parallel transmission will cause the accurate and it will solve the maximum clique problem in the theory of graph. The hop by hop routing protocol is integrated by the admission control mechanism. Finally the implementation phase was simulated by the mechanism based on BEPTC will effectively control the traffic load and offer QoS guarantee for admitted new flows all these lead the network to accommodate more flows with QOS guarantee and obtain higher system throughput make difference with other conservative approaches.
