Abstract: 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.
