Abstract
Wireless mesh network is an emerging technology progressing in the field of wireless networking. The broadcast nature of wireless mesh network allows each router to search destination and forward the packet. Wireless mesh network is based on IEEE 802.11 standard according to which the received packet must be acknowledged and the routers unacknowledged continue broadcasting packet in their range. This leads to signaling overhead and decreases throughput of the network. The proposed work overcomes this signaling overhead in addition to the design of a routing metric, expected forwarded counter (EFW) which deals with the problem of selfish behavior of mesh routers in wireless mesh network. EFW considers forwarding behavior of node and wireless link quality to select the most reliable and high performance path. The proposed system is evaluated by performing comparative analysis with the existing system by considering performance metrics like packet delivery ratio, average throughput, bandwidth utilization. The proposed work shows significant increase in throughput with efficient bandwidth utilization and the metric EFW selects a path with highest delivery rate, considering both quality of wireless links and reliability of network node in wireless mesh network.
