一种小规模水下无线传感器网络的部署算法

覆盖问题是水下无线传感器网络的一个基本问题。在虚拟力算法中,"虚拟"的力作为传感器节点部署策略被构造,以提高传感器节点的初始随机覆盖后的覆盖率。在传感器区域中,每个传感器节点都可以作为其它所有节点的"受力的源",这种力既可以是引力,也可以是斥力。基于虚拟力的概念,构造了节点间虚拟力区域,并提出了一种快速虚拟力算法。不同于其它虚拟力算法,这是一种简化的自组织算法,它能够有效地提高小规模的水下无线传感器网络的覆盖率。

An Small-scale Algorithm of Deployment in Underwater Wireless Sensor Networks

Coverage is an essential issue in the underwater wireless sensor network(UWSN).In the virtual force algorithm(VFA),the virtual force is constructed as a sensor deployment strategy to enhance the coverage after an initial random placement of sensors.In the sensor field,each sensor behaves as a source of force for all the other sensors,which can be either attractive or repulsive.Based on the conception of virtual force,a virtual force area of sensor nodes is constructed and a fast virtual force algorithm(FVFA...
