The Sector Cover and Transmission Weighted Greedy Algorithm for Connected Target Coverage in Directional Sensor Networks

The directional connected target coverage (DCTC) problem that schedules directional sensors to cover all targets and forward target information back to the sink to maximize system lifetime is still an important research issue in directional sensor networks. In this paper, a Sector Cover and Transmission Weighted Greedy Algorithm (SCTW-greedy algorithm) is proposed to construct the scheduling of sensors for the DCTC problem. The directional...
