This paper introduces MORE (More Opportunistic Routing & Encoding), a MAC-independent opportunistic routing protocol designed for wireless mesh networks. MORE addresses the limitations of the current opportunistic routing protocol, ExOR, by incorporating randomness in packet forwarding to avoid forwarding the same packets multiple times. This approach allows MORE to exploit spatial reuse and supports both unicast and multicast traffic without the need for a strict scheduler. Experimental results from a 20-node wireless testbed show that MORE achieves a median unicast throughput 22% higher than ExOR, with gains increasing to 45% when spatial reuse is possible. For multicast, MORE's gains increase with the number of destinations, ranging from 35% to 200% higher than ExOR. MORE also demonstrates practical benefits in terms of low complexity and efficient coding, making it suitable for deployment in mesh networks.This paper introduces MORE (More Opportunistic Routing & Encoding), a MAC-independent opportunistic routing protocol designed for wireless mesh networks.
