Abstract
Opportunistic routing is an emerging research area in Wireless Mesh Networks (WMNs), which exploits the broadcast nature of wireless networks to find the optimal routing solution that maximizes throughput and minimizes packet loss. Opportunistic routing protocols mainly suffer from computational overheads, as most of the protocols try to find the best next forwarding node. In this paper we address the key issue of computational overhead by designing new routing technique without using pre-selected list of potential forwarders. We propose a novel opportunistic routing technique for WMNs. We compare it with well-known protocols, such as AODV, OLSR, and ROMER based on throughput, delivery ratio, and average end to end delay. Simulation results show that proposed protocol, gives average throughput increase up to 32%, and increase in delivery ratio (from 10% to 20%). We also analyze the performance of proposed protocol and ROMER based on various parameters, such as duplicate transmissions and network collisions, by analysis depicts that proposed protocol reduces duplicate transmissions up to 70% and network collisions up to 30%
