摘要
无线传感器网络降低能耗、提高网络生存周期是研究的重要目标,本文针对LEACH算法缺陷,对簇首选择、簇首和Sink节点的通信进一步优化。簇头节点在接收簇内节点数据时进行数据聚合,减少传输数据的能耗,同时各簇头节点将聚合后的数据用改进的Dijkstra算法以最快的速度找到距离Sink的最短路径,提高网络性能,延长网络生存时间。
The primary aim of the study is to reduce the energy consumption of the networks of wireless sensors and to improve the life cycle of the networks, further optimizing the communications of cluster heads towards Sink nodes and cluster choices in view of the algorithmic defects of LEACH. Data aggregation is being conducted while cluster heads receiving the nodes data to reduce energy consumption in transmitting data. Simultaneously each cluster head finds the shortest route to Sink at the greatest speed for the aggregated data with the improved algorithm of Dijkstra to improve the network performance and to prolong the life time of the networks.
