Abstract
Nowadays, wireless sensor network which consists of numerous tiny sensors has been widely used. One of the major challenges in such networks is how to cover the sensing area effectively and maintain longer network lifetime with limited energy simultaneously. In this paper, we study hybrid network which contains both static and mobile sensors. We divide monitoring area into Delaunay Triangulation (DT) by using of Delaunay theory, based on the DT we estimate static sensors coverage holes and then work out the position of assisted mobile nodes in each triangle. In addition, we simulate our algorithm and compared with the previous methods on the platform MATLAB. The results show our algorithm is simpler and more efficient than the previous.
