Mesh is a network architecture that providing each node multiple possible connection path ways to every other node. Finding the path with the maximum available bandwidth in Wireless Mesh Network (WMN) is one of the parameter for supporting QoS. Here the authors propose a new routing metric called Efficient Path Selection(EPS) metric by considering bandwidth and physical distance between nodes as parameters. This metric identifies the optimal path from source to destination in WMN and incorporates with existing routing protocols, allows packets to go through the selected path. Signal strength decreases as distance increases and therefore packet loss occurs. But the previous efforts didn't considered physical distance of the link as parameter and also finding optimal path in a hop-by-hop manner has to be improved.
