摘　　要：传感器节点通常能量有限,如不加以合理使用就会影响到传感器网络的生命周期。现有的邻居节点切换方式和多径传输方式都没有能够有效地解决能量平衡问题。在证明基于决定性能量比例的传输原理基础上,提出一种有效的能量平衡的多径传输策略。仿真结果证明这种策略简单高效,容易实现。Sensor nodes are usually equipped with limited power. The lifetime of sensor networks will be affected due to the illegal used of the node＇s energy. The existing neighbor switching methods and the multipath delivery schemes have not efficiently solved the problem of the energy balancing. Firstly, this paper proves the delivery principle based on decisive energy ratio. And an efficient energy -balanced multipath delivery strategy is proposed. The simulations demonstrate the proposed strategy is very efficient and simple to be implemented.
