A study on control method of movable nodes for sensor networks

Combining wireless network and robotics technologies enables movable sensor nodes, which have various sensors, to communicate each other and move freely on the ground to build new sensor networks. They are called “Movable Sensor Networks” and interests in them have increased. “Movable Sensor Networks” are expected to be used in new situations. Applying these networks will make it possible to collect efficiently extensive environmental data by using less sensor nodes. If a node can communicate with another node while moving toward the destination node, they will configure a temporary network and the nearer node will plays a role in a dedicated relay node. Data collection time and the node moving distance can be largely reduced.
