摘要
针对基于最小代价场的无线传感器网络路由算法及其典型改进算法的缺陷,提出了一新的改进算法。新算法引入了一种跨层设计的思想,通过对各层协议的配合使用,优化生成扩展最小跳数场,使得信息包沿最短路径向Sink节点传送的过程中所引起的能量消耗最小化,并同时均衡节点负载。理论分析和仿真实验表明,该算法能够显著延长网络的生命周期。
Consider the deficiencies of routing algorithm based Minimum Cost Field for WSN and its typical improvement, a new improvement is proposed. The new improvement of the algorithm introduces an idea of multi-layer design. With the use of protocols of all layers,an extended minimum hop field is created. Then the packet is sent by the shortest path. , and the energy consumption will be minimum. The load of nodes will be balanced in this algorithm. According to the analysis and the simulation results, this algorithm has obvious advantages in extending the lifetime of the network.
