Design of a Laser Scan Localization Scheme for Sensor Nodes
A novel localization scheme called laser beam scan localization (LBSL) by combining grid and light (laser) with mobile localization policy for wireless sensor networks (WSN) is designed. The scheme utilizes a moving location assistant (LA) with a laser beam, through which the deployed area is scanned. The LA sends identification to unknown nodes to obtain the locations of sensor nodes. High localization accuracy can be achieved without the aid of expensive hardware on the sensor nodes, as required by other localization systems. The scheme yields significant benefits compared with other localization methods.
