During the past few years Opportunistic Routing (OR) gained a lot of attention as a way to improve the performance of wireless multi-hop Ad-hoc networks and wireless sensor networks. OR takes advantage of the broadcast nature of wireless communications to improve transmission reliability and throughput by forwarding data through a set of paths instead of one best path. In this paper, the authors describe the efficacy of OR by comparing it with traditional wireless routing protocols. Concurrently, they also outline several vital design issues that needs to be considered by OR protocols to make it more effective and deployable.
