一种新的水下立体空间WSN覆盖增强算法

当前热门的三维立体空间WSN覆盖方法应用在水下空间并不具有普适性。针对应用在水下的立体WSN覆盖方法通常存在覆盖率不高、节点移动能耗过大以及由此引起的节点能耗值差异较大等问题,结合现有的水下覆盖策略,提出一种新的基于降低节点能耗、提高水下空间覆盖率的水下空间层次化覆盖增强算法(underwater hierarchical space coverage-enhancing algorithm,UHSCA)。理论分析及仿真结果表明该策略对水下节点的精确性部署进行了性能优化,在改善节点部署过程中能量消耗均衡性的基础上降低了节点的整体耗能,水下空间覆盖率也有相应提高,对应用在水下侦察、水文监测等水下立体空间的WSN具有较强的实用性。

A new underwater WSN coverage algorithm on the three-dimensional based on space

The method of three-dimensional space WSN covering is popular currently, but is not universal for the applications in underwater space. There are some issues when the stereo WSN covering methods are applied in underwater space, such as the coverage is low, energy consumption of nodes mobile is excessive and nodes energy consumption are quite different etc. Combing with the existing underwater coverage strategy, we propose a new underwater space hierarchical spatial coverage enhancement algorithm (UHSCA), which based on reducing energy consumption and improving coverage of underwater space. Theoretical analysis and simulation show that this strategy optimizes the performance in the accuracy of deployment, it reduces the overall energy on the basis of improving energy balance during nodes deployment, and underwater spatial coverage also has a corresponding increase. The method has strong practicality in WSN which are used for underwater reconnaissance, hydrological monitoring in underwater three-dimensional space.
