摘要:

对无线传感器网络的节点能耗不均衡和传输时延的问题进行了研究,提出一种新的路由算法。该算法通过建立最小跳数和对节点剩余能量的保护,使得数据包沿着能耗最优的路径向Sink节点发送。在MATLAB环境下对该机制进行了仿真实验。实验结果表明,该算法能降低能耗,均衡和延长网络生存时间。

Abstract:

The problem of unbalanced energy consumption and transmission delay in Wireless Sensor Network (WSN) is studied, and a novel routing algorithm is proposed. By establishing the minimum hop count and protecting the remaining energy of the nodes, the algorithm makes packets traverse to Sink nodes through the paths with optimized energy. Simulation is carried out in MATLAB and it proves that the algorithm can balance energy consumption and increase the network lifetime.
