摘要
为了实现农田环境监测传感器网络节点合理布局,在分析应用需求基础上,提出基于采样间距rs和节点通信范围rc进行节点部署。设计了等边三角形、正方形、正六边形规则网格的系统节点部署和系统随机节点部署2种方法,并分别给出了2种方法中3种规则网格单元边长最大值的求解方法。此外,通过比较部署成本、连通性等指标探讨了最佳规则网格节点部署方案的选取原则,为农田环境监测应用中传感器节点的合理布局规划提供理论依据。
To realize feasible wireless sensor nodes deployment in farmland environmental monitoring, the sampling range rs and the communication range rc were proposed for deployment decision based on application requirements. Systematic random deployment and systematic regular deployment in patterns such as triangular lattice, square lattice and hexagon lattice were described in the paper, and the maximum lattice side in each pattern was also given. In addition, deployment cost and connectivity in these three regular patterns were discussed. The method can provide a reference for decision of sensor nodes deployment in farmland environmental monitoring.
