Robot-Assisted Target Localization using a Cooperative Scheme relying on Wireless Sensor Networks

In this article, a control/communication scheme for mobile robots operating in an uncertain environment in a target localization problem is considered. These robots need to exchange information with a base station via a mobile ad-hoc wireless network. This network is composed of both stationary and mobile nodes. Experimental results indicate a significant deterioration of the robot performance when the network is congested and the RF-signal strength is low resulting in loss of packets. Primitive, yet reliable cooperative schemes are evaluated in a target acquisition problem and experimental results are offered to validate the efficacy of the suggested scheme
