基于时延和能量优化的WSNs路由协议

Routing Protocol of Wireless Sensor Networks Based on the Delay Time and Energy Optimization

最小费用路由算法考虑了传输路径所要消耗的能量,最小跳数最小费用路由算法在最小时延的基础上考虑了能耗,但跳数小能耗相对大的节点容易失效。该文提出了一种基于时延和能量优化的加权跳数路由算法,有效缓解上述两种算法共同存在的瓶颈问题,并通过了数值算例对算法加以说明。

Minimal cost routing algorithm takes the energy consumption into account when transmitting infor- marion, minimal hops with minimal cost routing algorithm considers the energy consumption based on the mini- mum delay, which makes the node of less hops and relatively large energy consumption easy to failure. This paper presents a weighted hop routing algorithm based on the delay time and energy optimization, it effectively alleviates the bottleneck problem of them, ？ illustrated by numerical experiments.
