Abstract
The proposed algorithm to be explained in this paper is the localization technique using directional antenna. Here, it is assumed that anchor node has the ability to transfer the azimuth of each sector using GPS modules, sector antenna, and the digital compass. In the conventional sensor network, the majority of localization algorithms were capable of estimating the position information of the sensor node by knowing at least 3 position values of anchor nodes. However, this paper has proposed localization algorithm that estimates the position of nodes to continuously move with sensor nodes and traveling nodes. The proposed localization mechanisms have been simulated in the Matlab. The simulation results show that our scheme performed better than other mechanisms (e.g. MCL, DV-distance). ▸Keyword : Localization, Sensor network, Antenna, Ubiquitous, Anchor ∙제1저자 : 홍성화 ∙투고일 : 2009. 10. 15, 심사일 : 2009. 11. 11, 게재확정일 : 2010. 01. 26. *동양공업전문대학 전산학부 소프트웨어공학과 112 韓國컴퓨터情報學會 論文誌(2010. 1.)
