UWSNs中基于AUV移动的覆盖盲区修复算法

Coverage Blind Restoration Algorithm Based on AUV Movement in UWSNs

提出了一种水下无线传感器网络(UWSNs)中基于自主水下航行器(AUV)移动的覆盖算法。首先将要覆盖的区域网格化,然后以适当的策略遍历各个小格,从而实现盲区的覆盖修复。该算法克服了水下环境复杂未知、覆盖场景多样化而难以可靠覆盖的问题,同时使得AUV路径移动消耗最小化。文中还对3D场景和多AUVs协同等情况进行了分析和探讨。仿真实验表明,该算法在覆盖盲区规则、不规则或不连续等场景下均有较好的表现。

This paper proposed a coverage blind restoration algorithm based on AUV Movement in underwater wireless sensor networks（UWSNs）.Firstly,the area to be covered is mapped into many hex cells,and then in order to achieve restoration of coverage blind,the AUV traverses each cell according to a proper strategy.The algorithm overcomes the problem that the underwater environment is complex and unknown so that it is difficult to reliably cover the scene.It also helps the AUV to minimize the consumption of traversing paths.We also analyzed and discussed the situation of 3D scenes and multiple AUVs collaborations.Simulation results show that the algorithm performs well on the restoration of coverage blind,no matter the scenes are regular,irregular or discontinuous.
