摘要：

We describe, design, implement, and evaluate a novel localization scheme based on light 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 band of light, 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 expensive hardware on the sensor nodes. The scheme yields significant benefits compared with other localization methods. In particular, BLS is a low-cost scheme because it does not require any infrastructure or additional hardware for sensor nodes. (C) 2013 Elsevier GmbH. All rights reserved.
