A Power Saving Scheme taking into Account Coverage and Connection Problem in WSNs

Coverage and connection problem have been the question which worth exploring in wireless sensor networks (WSNs). How to use connected sensors to cover the designate area is the major goal. Currently, some peoples have studied this problem, but their proposed methods focused on 2D ideal plane or 3D full space. However, the actual terrain is rugged and uneven. Therefore, the exist solutions cannot obtain the fairest information, so we use Spline function to shape the FoI(Field of Interest) from the undulate terrain. Furthermore, we use the feature of convex hull of Spline function to ensure the full coverage for FoI. And we propose a shorter transmission path algorithm to reduce network latency and energy consumption between sensors. In evaluation results, our proposed algorithm provides more efficient connection and a guarantee of high coverage in the same time.
