摘要
无线传感器网络中的节点能量有限且较难补给,网络生命周期难以保证,这大大影响了其应用的场景和范围。为解决上述问题,提出了一种新的路由算法EDROPL,算法通过将网络进行区域划分,引入能耗梯度概念,采用适当的评价函数指导簇首节点的选择,同时采用簇首之间层次转发数据等方法优化路由。仿真实验表明,EDROPL相对于LEACH算法以及LEACH-A算法、HRPNC等其他能耗模型算法能更好的均衡网络能耗,提高网络生命周期。
The energy of the nodes in wireless sensor network is limited and difficult to be supplied,so the network life circle is hard to be ensured,which has a negative effect on being used in so fields and ranges. To overcome the disadvantages above,a new routing algorithm called EDROPL is proposed. This algorithm optimize routing by divid？ing sections,importing the concept of energy gradient,choosing the cluster heads by some appropriate evaluation function,and transmitting packages between cluster heads. The simulation result shows that EDROPL has a better performance in balancing the network energy consumption and improving the network life circle comparing with LEACH,LEACH-A and HRPNC energy based algorithm.
