Leveraging RSSI for Robotic Repair of Disconnected Wireless Sensor Networks

Many recent deployments of environmental sensor networks have focused on obtaining measurements across large and inhospitable areas. With increasing scale it becomes impractical to deploy or maintain such systems by hand. This paper evaluates large scale network disconnectivity and highlights the underlying issues related to the environment and node characteristics. Furthermore, it examines how a low cost and adaptive method of robotic repair can be applied to large area networks using received signal strength measurements for simple navigation and placement.
