Opportunistic routing (OR) is a recent routing technique for wireless multihop networks. It exploits the broadcast nature of wireless medium which is not utilized by traditional routing. The important features of OR is selection of forwarding nodes and co-ordination among the nodes to deliver the packets to their destination. Therefore, OR works well in wireless multihop networks with higher node density such as mesh or sensor networks. OR enables multiple paths and dynamic relay selection, thus it obtains higher link reliability and larger transmission range. This paper reviews some of the OR protocols.
