Wireless Mesh Network (WMN) is a wireless networking model which currently attracts research and industry. In WMN every node passes information to the nearest node and there may be number of hops from one node to the other. In WMN the information is forward using the best possible route to any destination. The best path can be determined using the routing protocol. The congestion problem arises when every time routing protocol determines the same best path due to which traffic load occurs on that path while other path seldom used. Due to the abrupt use of single path the packets may drop causes the greater effect on the network's performance.
