摘要 针对能量异构的无线传感器网络,提出一种新的基于能量分布的非均匀分簇算法(EDUCRA)。在该算法中,距汇聚点较近的节点直接与汇聚点通信、簇首使用非均匀的竞争范围来构造大小不等的簇。通过在OMNet++平台上的仿真结果表明:该算法可以有效均衡网路能量消耗,提高节点能量利用率,延长网络寿命。 Aiming at energy heterogeneous wireless sensor networks(WSNs),a new energy distribution-based uneven clustering routing algorithm(EDUCRA)is proposed.In this algorithm,the node near the sink communication with sink directly,and cluster heads use uneven competition ranges to construct clusters of uneven sizes.The results of the simulation on OMNet++ platform show that the algorithm can balance network energy consumption,improve utilization efficiency of node energy and prolong network lifetime.
