Coverage is one of the basic problems that any wireless sensor network application must solve properly to achieve the expected quality of service. The communication distance of wireless sensor network nodes is limited, the initial energy is low, and many optimization objectives need to be considered in the deployment, which makes the network deployment optimization very complicated, and many problems are difficult. In essence, the deployment problem is a multidimensional nonlinear optimization problem with continuous discrete variables. In order to meet the needs of network monitoring, this article establishes a reasonable mathematical model according to the research objectives. By adjusting node position to obtain better network coverage effect, an optimization algorithm of monitoring area coverage based on control node position is proposed. By calculating the new location of nodes, more monitoring areas can be covered by the nodes. The simulation results show that the proposed algorithm can improve the coverage effect rapidly.

无线传感器网络中基于控制节点位置的覆盖优化算法

覆盖是任何无线传感器网络应用必须妥善解决以达到预期服务质量的基本问题之一。无线传感器网络节点的通信距离有限，初始能量低，部署时需要考虑很多优化目标，使得网络部署优化非常复杂，问题很多。本质上，部署问题是一个具有连续离散变量的多维非线性优化问题。为了满足网络监控的需要，本文根据研究目标建立了合理的数学模型。通过调整节点位置以获得更好的网络覆盖效果，提出了一种基于控制节点位置的监控区域覆盖优化算法。通过计算节点的新位置，节点可以覆盖更多的监控区域。仿真结果表明，所提算法能够快速提高覆盖效果。
