Elimination Algorithm for Redundancy of Acknowledgment in Reliable Broadcast/Multicast
Dalong Zhang · Jisuanji gongcheng · 2009
To improve the efficiency of reliable broadcast/multicast MAC protocol in Wireless Sensor Network(WSN),this paper proposes an elimination algorithm for redundancy of acknowledgment based on geographical location information.This algorithm uses neighbors’ geographical location information to construct the minimum equivalent collision area for broadcast/multicast packet,which wipes off the redundant nodes from receiver nodes set in terms of acknowledgement.Simulation results show that this algorithm can decrease the number of nodes joining in acknowledgment with reliability,reduce packet sending cost and guarantee the packet transmission quality more efficiently.
