Research on Directional Path Coverage Enhancement Algorithm of Multiple Objects in 3 D Underwater Mobile Sensor Networks
摘要
Abstract
Collaborative tracking of multiple moving targets in mobile 3D underwater sensor networks remains to be a conundrum;therefore, this paper presents a distributed multi-target path coverage enhancement algorithm to be directed against above problem. Underwater sensor nodes are assumed to be mobile due to ocean current and the detective targets have the ability of autonomous mobility in practical mobile 3D underwater sensor networks. The movement law of underwater sensor nodes and multiple moving targets comply with Meandering Current Mobility models and Random Walk mobility model based on probability respectively. In our algorithm, the maximal path coverage ratio of multi-target trajectory paths is achieved by the collaborative decision-making within the two-hop neighbor nodes. The directional coverage orientations is decided with the objective to maximize path coverage ratio, moreover,the coverage ratio standard deviation of different target trajectory paths remains to be as small as possible. Finally,the effectiveness of distributed coverage enhancement algorithm is verified by MATLAB simulation and the results proved significantly improvement of multi-target path coverage ratio.关键词
