Wireless mesh networks have emerged as adaptable and low cost networks. Selfish behavior of mesh routers degrades performance. Expected Forwarded Counter (EFW) is a cross layer metric which combines link quality and forward reliability has been introduced to deal with the problem of selfish behavior in order to provide reliable routing. This paper proposes an enhancement to the EFW, by considering congestion incurred due to selecting only high quality paths. The performance of proposed metric is evaluated through simulation. Simulation results show that overall routing performance has been increased in terms of throughput and packet delivery ratio.
