摘要
将待监测水域中水质参数波动较大的区域定义为重点监测区域,水质参数波动较小的区域定义为非重点监测区域。重点监测区域由于其水质参数波动频繁,需要覆盖更多的传感器以提高其检测精度。为提高资源利用率,在不增加传感器个数的情况下,将非重点监测区域内的传感器移动到重点监测区域中。首先,利用Voronoi图定位重点监测区域目标节点的位置,根据能量矩阵确定移动节点和目标节点一一对应的关系。然后,通过点对点移动策略(PPMS)实现对节点的重新部署,使重点监测区域得到更加有效的覆盖。仿真结果表明,该方法可以较大程度地减少传感器的移动距离,减少网络达到平衡点的时间,在不影响整体监测水域监测效果的情况下,实现对重点监测区域更为有效的覆盖。
The areas with large fluctuation of water quality parameters in the water area to be monitored are defined as the key monitoring areas,and the areas with small fluctuation of water quality parameters are defined as the non⁃key monitoring areas.As the frequent fluctuations of the water quality parameters in the key monitoring areas,the more sensors need to be covered to improve their detection accuracy.The sensors in the non⁃key monitoring area are moved to the key monitoring area without increasing the number of sensors,so as to improve the resource utilization rate.The Voronoi diagram is used to locate the target node of the key monitoring area,and the one⁃to⁃one correspondence between the mobile node and the target node is determined according to the energy matrix.The redeploy of the nodes are realized by means of the point⁃to⁃point mobility strategy(PPMS),so that the key monitoring areas can be more effectively covered.The simulation results show that the method can reduce the moving distance of the sensor to a large extent and the time for the network to reach the equilibrium point.It can achieve more effective coverage of the key monitoring area without affecting the monitoring effect in the overall monitoring water area.
