Abstract: In wireless mesh networks, the routing of packets from source to destination is crucial and challenging task. The wireless mesh networks find applications in disaster management, video on demand, intelligent, health care systems, etc. Various routing protocols exist in literature to improve the efficiency of the wireless mesh networks calculated in terms of reliability, cost, throughput, error rate, etc. The opportunistic routing proves to be more efficient protocol best suited for wireless mesh networks as it avoids duplicate transmission and improves performance of the network. The routing metrics are essential to evaluate the best possible path for packet delivery. This paper conveys the essence of the existing metrics used for analyzing the routing protocol considered for evaluation. Further we introduce a new opportunistic routing metric called Unified Expected Distance Progress with Successful Transmission Rate (UEDPSTR) which is compared with the characteristics of the network.
