一种移动无线视频传感器节点的覆盖算法

在现有的无线传感器网络覆盖算法的研究中,缺乏对移动节点路径规划的研究,而针对具有视频传感器节点的网络仍使用普通传感器圆形覆盖区域的测量方法来计算覆盖面积,并不完全符合实际情况.基于这两方面的原因,本文提出了一种适用于无线视频传感器节点的最大覆盖算法,并提出一种对于视频传感器节点覆盖面积的计量方法.该算法能够使节点在保证网络连通性的前提下,达到最大的有效监测范围.此外,本文建立了相应的仿真实验模型,对该算法的有效性和覆盖面积进行了实验与分析.结果表明,本算法的节点监测面积大约为使用随机运动算法的节点监测面积的1.5倍左右,并可以保证网络的连通性.

A Coverage Algorithm of Mobile Wireless Video Sensor Node

The existing wireless sensor networks coverage algorithms are usually for static nodes, and it is unsuitable to measure coverage area with circle mode in the wireless sensor networks with video nodes. Since the two sides, a coverage algorithm of mobile wireless video sensor nodes and a measurement method for video sensor node coverage area are proposed. Every node also can be kept in an effective distance by using the algorithm, thereby making sure the network connectivity. A simulation model is offered to test the efficiency and measure monitoring area of the algorithm. The result represents that the coverage ratio of the algorithm is about 1.5 times than random algorithm as keeping the network communication efficiently.
