One of the major research issues in the Wireless Mesh Network (WMN) is routing. The routing protocols of ad-hoc networks can be applied for WMN, but have limited success because, ad-hoc networks are mainly structure less networks with highly dynamic topology and harmonized nodes, where WMN are relatively static network with two types of nodes, one fixed mesh routers and mobile clients. In layered routing protocol, source node initiates a path establishing process whenever path breaks. It will cause huge control packets and increase packet loss. This is not an ideal method in WMN where every nodes rather than source and destination in the path are motionless.
