摘　　要：阐述无线传感网络中多sink节点调度,提出多目标优化的移动汇聚节点调度模型,改进NSGA-Ⅱ算法。该模型以能耗最小以及覆盖率最大作为优化目标,通过预测节点寿命来构筑新的目标函数,对节点死亡轮数进行聚类并以此为基础进行汇聚节点移动调度,减少了网络拓扑结构变化带来的影响。This paper describes the scheduling of multiple sink nodes in wireless sensor networks, proposes a multi-objective optimized mobile aggregation node scheduling model and improves NSGA-Ⅱ algorithm. The model is the smallest energy consumption and the maximum coverage is the optimization target, and the new target function is constructed by predicting the node life, clustering the number of node deaths and the basis for convergence node movement scheduling, reducing the impact of network topology changes.
