摘要:

为解决智慧园区中无线传感器网络(WSN)的能耗不均衡问题,构建了路由代价函数,并提出了一种新的能耗均衡路由算法。该算法结合智慧园区中无线传感器网络的特点,综合考虑节点地理位置和剩余能量来构建路由代价函数。传感器节点通过选择其邻居节点中路由代价最小的节点进行数据转发。仿真结果表明,该算法可以有效节约网络能耗,同时延长了网络的生命周期。

Abstract:

To solve the energy problem in wireless sensor networks used for smart park,an optimized routing algorithm based on routing cost in WSN was proposed.According to the characteristics of smart park,the algorithm took a comprehensive consideration of the remaining energy and geographical location of nodes and exploited a new routing cost function.The sensor nodes selected the node with the minimum routing cost to forward the packets.Simulation results show that the algorithm significantly reduces the energy consumption of the network and extends the network lifetime effectively.

Key words: smart park, wireless sensor network, routing cost, network lifetime
