摘要
针对开放式水域中水下事件位置的稀疏和不确定特点,该文给出一种水下传感器动态分布式布置方法。指出了与传统鱼群行为有差别的类鱼行为,在此基础上给出了水下传感器搜寻策略,并形成了动态布置方法。该布置方法通过初始布置和满足Lévy分布的类鱼探索行为扩展水下传感器的搜寻空间,有效增加了水下监测系统的事件覆盖率。改进后的尾随行为既能保证对同伴行为的有效感知,又能避免节点之间的通信,提高了传感器节点能效,增加了整个监测系统的隐蔽性。
In view of that the events in open waters are sparse and uncertain,the dynamic distributed arrangement for underwater sensors is presented here. The fish-action model being different from the traditional fish swarm algorithm is proposed,and then the hunt policy is given based on the fish-action to form the dynamic deployment method of underwater sensors. Through initial deployment design and explore-action in the Lévy distribution,this method expands the space under exploration and increases the event coverage of underwater surveillance system. Meanwhile,the improved follow action endues sensors with the effective perception ability on others and turns off the communication among sensors. Thus,the energy efficiency of sensors is improved and the concealment of underwater surveillance system is ameliorated.
