A Hybrid Solution For Coverage Enhancement in Directional Sensor Networks

In Directional Sensor Networks (DSNs), motility capability of a directional sensor node has a considerable impact on the coverage enhancement. Motility capability may overcome overlapped field of views and occluded regions occurring during the initial deployment. On the other hand, adjusting working directions could not always heal coverage holes. Using mobility is the only solution under these circumstances. However, the high cost of mobile sensors and the high energy consumption of their physical movement are the two important constraints for their use. In this paper, a hybrid solution has been proposed for the coverage improvement in DSNs. This hybrid solution increases the total coverage by up to 31% after the initial deployment. Besides
