Layer Metrics for Reliable Messaging in Wireless Mesh Network
Wireless Mesh Network (WMN) is an emerging technology encouraging the developments for next generation wireless networking. Wireless mesh network is based on IEEE 802.11 standard according to which, the received packet must be acknowledged. The presence of selfish mesh routers may drop the packets sent by other nodes. To deal with the problem of selfish behavior of mesh routers, this paper proposes a reliable routing metric, Expected Forwarded Counter (EFW) and its two variants. EFW improves the wireless link quality by selecting the most reliable and high performance path and it also considers the forwarding behavior of node.
