摘要 为了提高无线传感器网络整体能源利用率,降低工作能耗,分析了网络负载不平衡的因素,引入了移动Agent技术,提出了一个智能、灵活的负载平衡机制;文中建立了通用的MA—WSN模型,设计了角色表、角色切换和度量公式以及负载平衡的完整算法;解决了不同节点能源利用程度相差大的问题,均衡了网络能耗,达到了网络寿命延长;实验结果表明,全网工作时间同比延长25%~35%;提出的方法对负载平衡进行了智能化方面的尝试,适用于野外探测等无人作业的环境,尤其对节点数量多、规模大的网络效果明显。 In order to settle unbalance load in WSN, by introducing mobile agent technology, the paper proposes a load balance mechanism. MA WSN is built special for WSN, and role-table, role-switching, metric standard are designed. Also load balance flow is shown. The problem is settled that energy utilization is very different between nodes, then net working hours is prolonged. The result shows the life of the whole net can extend 25%-35% without manual intervene. In particular the method is fit for field military scene.
