Energy efficiency, Reliability and on demand data delivery are the usual challenging factors encountered in mobile ad hoc networks. Previously used ad hoc routing protocols where guard nodes relay the packet with prioritized back off time when the intended node fails and becomes a contender nodes themselves are inefficient considering MANET susceptibility due to node mobility. So the authors propose a MAC independent approach called Position-based Opportunistic Routing (POR) that uses location information to guide the data flow and can always achieve near optimal paths during data transfers. Utilizing on demand routing table backup mechanism, communication is maintained without being interrupted. Forwarding candidates are coordinated using the candidate list comparison available at every node.
