Energy-aware broadcasting method for wireless sensor network

초록

The communicative behaviors in Wireless Sensor Networks(WSNs) can be characterized by two different types: routing and broadcasting. The broadcasting is used for effective route discoveries and packet delivery. A blind flooding approach for broadcasting generates many redundant transmissions. The Dominant Pruning(DP) algorithm is reduced the redundant transmissions of packets based on 2-hop neighborhood information. However, in DP(include TDP/PDP) algorithm, a particular node is frequently selected as a rebroadcasting node and its life-time is shortened. As a result, DP algorithm is insufficient in terms of the overall energy dissipation in sensor network. In this paper, we propose the algorithm based on Partial Dominant Pruning(PDP) algorithm to enhance sensor network lifetime. We compare and analyze the simulation result of our algorithm with PDP.
