Abstract
Wireless sensor network (WSN) has been widely applied in the civil and military domains due to its wide coverage and remote monitoring capabilities. With high mobility and flexible deployment, unmanned aerial vehicles (UAVs) provide opportunities for efficient data collection and precise sensor localization of WSN. In this paper, we divide the WSN into regular hexagonal network cells (NCs) and apply a UAV for sensor localization and data collection. A sensor localization scheme based on received signal strength (RSS) is proposed. Further, Cramer-Rao lower bound (CRLB) of the sensor coordinates and the per-node capacity of WSN are derived. The simulation results show that there is a trade-off between the localization error of sensors and per-node capacity of WSN. This paper hopefully provides some guidelines and insights for joint sensor localization and data collection in UAV-assisted WSN.
