The Study Of Routing Protocol In Wireless Mesh Network

WMN (short for Wireless Mesh Network), is a new structure of the network and is accepted by the 802.16, 802.16e and the future 802.11s protocol standard. The self-organize, self-aid and effective management of the mobile users need a high-performance routing algorithm.A wireless backbone-based Distributed mesh network routing protocol(WIME) based on Ad hoc demand distance vector, which is suitable for middle scale wireless mesh network, is proposed in this paper. The protocol can supports two wireless clients in different BSS (Basic Service Set) communicate with each other by wireless relaying. Redundancy messages can be significantly reduced by exchanging load information between central nodes and loop path is eliminated.The paper implements the simulation of the WIME algorithm. The result of the study validates that the algorithm has high routing performance while reducing the redundant route and implementing the communication between terminals in different subnet.
