一种分布式高效节能的自适应传感器网络聚类协议

Distributed energy-efficient adaptive clustering protocol in wireless sensor networks

现有的传感器网络拓扑协议未全面考虑节点位置、剩余能量等因素影响,算法的稳定性、能量有效性不足。提出一种分布式高效节能自适应传感器网络聚类协议(DEAC)。该协议通过增加等比能量约束项,利用节点的剩余能量信息,改变候选类首的选择概率,再基于邻居节点候选类首的信息,选择合适的类首。实验结果表明:与LEACH,HEED等拓扑协议相比,DEAC可有效减少网络总能耗、平均网络各节点的能量消耗、延长网络的生存时间,性能超过LEACH,HEED等聚类协议。

The current topology protocols in WSNs can reckon without the influence of the node＇ s location and the residual energy, so the algorithm stability and the energy efficiency are incompetent. A distributed energy-efficient adaptive clustering （DEAC）protocol in WSNs is educed. By increasing the restriction of energy and utilizing the residuary energy information of the node, the protocol alters the probability of the node as cluster-head candidate. Then cluster-head is selected based on the neighborhood information of cluster-head candidate. The result of the test shows that compared with the LEACH and the HEED, DEAC protocol can effectively lessen the energy consumption of network and average the burden of the nodes＇ energy consumption to prolong the networks＇ lifetime. The DEAC outperforms the LEACH and the HEED.
