【摘要】：针对无线传感器网络中存在的节点能量受限、网络循环利用周期短、吞吐量少等问题,提出了基于分簇的动态路由协议KACO。算法初始阶段采用改进的K-means聚类和蚁群聚类算法获得网络分簇;综合考虑节点的能量效率、当前节点与基站的距离、节点与簇内其他节点间的距离3个方面的因素选择簇头节点。在数据传输阶段,根据节点间的距离动态调整传输路径,有效地减少了节点在数据传输时的能量消耗。实验结果表明,与其他基于分簇的网络节能方法相比较,该方法取得了较好的性能。
[Abstract]:Aiming at the problems of limited node energy, short cycle utilization period and less throughput in wireless sensor networks, a cluster-based dynamic routing protocol (KACOO) is proposed. In the initial phase of the algorithm, the improved K-means clustering and ant colony clustering algorithms are used to obtain the network clustering, and considering the energy efficiency of the nodes, the distance between the current node and the base station is considered. The distance between the nodes and other nodes in the cluster is determined by three factors: cluster head node. In the stage of data transmission, the transmission path is dynamically adjusted according to the distance between nodes, which effectively reduces the energy consumption of the nodes in data transmission. The experimental results show that the proposed method has better performance than other clustering based network energy saving methods.
