摘要
在基于无线传感网络(WSNs)农业监测系统中,传感节点需周期收集环境数据,如温度、湿度,并且以尽可能少的传感节点实现对监测区域的随时监测。为此,提出一种基于太阳能的调度节点移动的覆盖率优化(SPMSC)方案。在SPMSC方案中,每个移动节点能够利用太阳板获取能量。通过预测太阳能的数量决定节点的移动方案,实现以最少节点和最小的能量消耗最大化覆盖区域。仿真结果表明,与同类方案相比,提出SPMSC方案的节点数下降了4%,网络寿命提高了10%。
In agriculture monitoring system based on wireless sensor networks（WSNs）,the sensing nodes need periodically collect the environment information such as temperature and humidity,and the sensing nodes are used as little as possible to timely monitor the monitoring field. A scheme of solar power-moving schedule of mobile-based optimal coverage（SPMSC）is proposed. In SPMSC scheme,each mobile node can acquire energy by means of solar panel. The node movement scheme is decided by means of the prediction of solar energy to realize the maximum coverage area with least nodes and minimum energy consumption. The simulation results show that,in comparison with similar schemes,the nodes is decreased by 4% and network lifetime is increased by 10% in SPMSC scheme.
