Abstract: We describe an algorithm for indoor mobile robot navigation using wireless sensor network. In our navigation system, a robot can navigate autonomously without the need for a map, a compass, or GPS. We use only several sensor nodes with ultrasonic sensors. Sensor nodes are deployed in an indoor environment and each sensor node has routing paths to all available destination-nodes through flooding. Measuring the distance from one sensor node after another along the routing path, the mobile robot moves toward the direction that shorten the distance and finally comes to reach the destination. The validity of the proposed algorithm has been proved by many experiments. 1.
