摘要 针对WSN数据汇集应用中,由于负载分配不均衡,使得网络节点出现早死,缩短网络寿命问题,提出一种面向WSN数据汇集应用的动态负载均衡算法(DLB-DGA)。DLB-DGA算法采用压力传输和压力均衡的思想,通过压力计算模型和流量均衡计算模型,动态调整子节点转发给父节点的数据流量比例,使网络上游节点的负载逐渐趋于最大程度的均衡,延长网络寿命。仿真实验表明DLB-DGA算法可行。 In data gathering application of Wireless Sensor Networks（WSN）,the unbalanced load causes premature death of sensor nodes and shortens the network lifetime.The Dynamic Load-Balancing algorithm for Data Gathering Application （DLB-DGA） is proposed.Motivated by the idea of pressure transfers and pressure balancing,the pressure transfers model and load-balancing model are proposed,by which the network can reach the maximum degree load-balancing step by step.Experimental results validate the effectiveness of this approach.
