A Hybrid Solution For Coverage Enhancement in Directional Sensor Networks

Keywords: Directional Sensor Networks; Coverage; Cost; Energy Efficiency; Motility; Mobility; Hybrid Deployment

Abstract:
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 occuring 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 study, 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, a new hybrid deployment model for DSNs has been discussed and the performance results of this model have been presented.
