面向水环境的传感网虚拟距离覆盖算法

针对水面传感器随机部署时网络覆盖率较低的问题,采用了一种面向水环境的无线传感网虚拟距离覆盖算法,在保证连通性的前提下提高网络的覆盖率。在虚拟距离算法中,每个传感器节点的运动受到3个虚拟距离的影响:节点之间的虚拟距离、未被覆盖区域格点与节点的虚拟距离以及边界与节点间的虚拟距离。仿真结果表明:该算法可以有效地提高网络覆盖率。可以得出以下结论:虚拟距离算法通过对节点位置的控制更新有效提高了网络覆盖率,使节点得到优化部署。

Virtual distance coverage algorithm for sensor network in water environment

Aiming at the problem of low network coverage when the surface sensor is randomly deployed, a virtual distance coverage algorithm of wireless sensor networks for the water environment is adopted to improve the coverage of the network under the premise of ensuring connectivity. In the virtual distance algorithm, each sensor node is influenced by three virtual distances, which are the virtual distance between nodes, the virtual distance between the unregistered region grid and the node, and the virtual distance between the boundary and the node. The simulation results show that the algorithm can effectively improve the network coverage. It can be concluded that the virtual distance algorithm improves the network coverage effectively by optimizing the control of the node position, so that the deployment of nodes can be optimized.
