In order to improve the location accuracy of a target, various methods for improving the performance of a single sensor node have been studied in sensor network. However, there is little research to improve the location accuracy using data fusion and sensor node deployment at system level. Therefore, this paper proposed a method to improve the location accuracy using data fusion and sensor node deployment. We implemented the proposed data fusion system and simulated various sensor node deployments. As a result, the proposed method improved the location accuracy of about 1.67m. In addition, we have found an optimal deployment that satisfies a required performance under limited sensor node resources.
