Reliable and on-time data delivery is a crucial parameter of network performance in highly dynamic mobile ad hoc networks. Leveraging on a modified 802.11 MAC tweak, guard nodes relay the packet with prioritized back off time when the intended node fails and becomes a contender nodes themselves. Previously used ad hoc routing protocols of Mobile Ad-hoc NETwork (MANETS) are susceptible to node mobility, especially for large-scale networks because of this tweak. To address this issue a MAC independent approach called Position-based Opportunistic Routing (POR) protocol uses location information to guide the data flow and can always archive near optimal path.
