A Location Aid Algorithm to Eliminate Redundant Nodes for Reliable Broadcast/Multicast MAC Protocols
Qing Li, Hongyi Yu, Dalong Zhang · 2008
To improve the efficiency of reliable broadcast/multicast MAC protocol in wireless multi-hop network, a location aid algorithm to eliminate redundant nodes was brought forward. Using the neighbor geographical location information, according to the principle of equivalent collision region, the algorithm could reduce redundant nodes from receivers, which is unnecessary for acknowledgement. Thus, the minimum acknowledgement nodes set is got. Extensive analysis and simulation results validate the reliability and efficiency of it.
