传感器部署是物联网中的一个基本问题。本文研究了在低密度传感器的移动传感器网络中，如何对完全无法实现覆盖的优先事件区域进行有效的部署。在检测到事件区域的情况下，研究了如何使移动节点移动到合适的位置进行有效部署的问题。首先，定义了事件区域优先级函数的覆盖权值。推导出当所有节点的复盖权相同时，复盖率最大化的结论。提出了一种结合复盖、权重和虚力的节点部署策略。仿真结果表明，所提出的部署算法是准确有效的。版权所有©2015 John Wiley&Sons，Ltd.
Sensor deployment is a fundamental issue in Internet of things. In this paper, It addressed the problem of how to effective deployment for prioritized event area in mobile sensor networks with low density sensors, which coverage completely cannot be realized. When event areas have been detected, the problem how to make mobile nodes moved to a suitable place with effective deployment is studied. Firstly, a coverage weight by priority function of event area is defined. It deduced conclusion that coverage effectiveness have maximization as if all of nodes coverage weight are identical. A nodes deployed strategy have presented that combined coverage weight and virtual force. Finally, some simulations shown that the proposed deployment algorithm are accurate and effective.
