In wireless mesh network, while transmitting packets or data in the network, multiple number of traversal can occur which responsible to maximize the routing cost. To overcome this problem this paper synthesizes on ETOP (efficient transfer on path) technique to find out the efficient route which helps to optimize the routing cost, our aim is to find the best path having minimum cost to reduce the more energy consumption. AODV is an excellent choice for mesh network route establishment hence; in this we have used AODV protocol. We implement and evaluate a routing approach based based on a 40-node indoor mesh network. In this we have calculate normal cost and minimum cost by AODV to gives difference between normal cost and minimum cost. Again we are finding the delay at each iteration.
