A location aid reliable broadcast/multicast MAC protocol

To improve the efficiency of reliable broadcast/multicast MAC protocol in wireless multihop network, a location aid reliable broadcast/multicast MAC protocol was brought forward. Using the neighbor geographical location information, according to the principle of equivalent collision region, the protocol could reduce the redundant nodes from receivers, which is unnecessary for acknowledgement. Thus get the minimum acknowledgement nodes set. Extensive analysis and simulation results validate the reliability and efficiency of our reliable broadcast/multicast MAC protocol.
