摘要：
Node localization is a fundamental problem in wireless sensor network. There are many existing algorithms to estimate the locations of the nodes. However, most of the methods did not consider the presence of obstacles. In practice, obstacles will lead to blockage and reflection of communication signals between sensor nodes. Therefore, the presence of obstacles will greatly affect the localization result. In this paper, we implement an obstacle-handling algorithm based on the localization tool developed by MIT, The experimental result shows that the enhanced algorithm can reduce the average distance error by up to 46%, compared to the original algorithm. © 2012 Institute of Automation, Chinese Academy of Sciences and Springer-Verlag Berlin Heidelberg.
