多源多汇聚WSN中的能量有效路由算法
首发时间:2016-12-21
摘要:随着物联网(Internet of Things, IoT)的迅速发展,无线传感器网络(Wireless Sensor Network, WSN)作为其核心部分受到研究人员的广泛关注。WSN中随机部署了大量低成本、低功耗且可进行短距离无线通信的传感器节点,负责采集监测区域内被监测对象的数据。由于节点电池能量有限且通常被部署在人员不可达的环境,无法通过充电或更换电池的方式对其进行能量补给,所以WSN路由协议应主要专注于能量效率这一性能指标。本文从供应链协同的角度出发,提出一种适用于多源多汇聚WSN的能量有效路由算法。仿真结果表明,该算法在网络能耗和路由重构速度方面具有良好的性能。

Energy Efficient Routing Algorithm in Multi-Source Multi-Sink WSN
Abstract:With the rapid development of Internet of things, WSN, which is the core part of IoT, has received extensive attention from researchers. Large numbers of sensor nodes, which feature low cost, low power consumption and short distance communication, are randomly deployed to collect data in the monitoring area. Considering sensors in WSN are usually deployed unattended in harsh environments, recharging or replacement of sensors are almost impossible. Thus energy efficiency is of great importance on the design of routing in WSN. In this paper, from the view of supply chain collaboration, we proposed an energy-efficient routing algorithm which is suitable in multi-source multi-sink WSN. Simulation results verified that our algorithm has achieved good performance with respect to the reduction in energy consumption and the rate of routing reconstruction.
