Fine-Grained Localization With Pairwise Nodes Coverage
Localization is an important design issue in wireless sensor networks. In this paper, the authors will focus on the sensor deployment for localization with the consideration of coverage and accuracy. Their pairwise localization pattern requires the information of only two coverages for the target. With this information, there are two possibilities of the position. In order to determine the correct location, the authors design minimum node deployment with regular pattern and an Adaptive Sequence based Localization algorithm (ASL). The proposed ASL algorithm could accurately localize the node in the monitoring area with minimum cost.
