Abstract

We design a novel localization scheme called laser beam scan localization (BLS) by combining grid and light (laser) with mobile localization policy for wireless sensor networks. The scheme utilizes a moving location assistant (LA) with a laser beam, through which the deployed area is scanned. The LA sends IDs 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. First, BLS is a distributed and localized scheme, and the LA broadcasts IDs while unknown nodes listen passively. No interactive intersensor communications are involved in this process; thus, sensor energy is saved. Second, BLS reaches a sub-meter localization error. Third, because equation is simple, computational cost is low. Finally, BLS is a low-cost scheme because it does not require any infrastructure or additional hardware for sensor nodes.
