Abstract:

In this paper, the accuracy of location estimation of ad hoc deployed sensor nodes for a wireless sensor network in the presence of noisy environment and obstacle is discussed. Considering estimation accuracy, energy efficiency, and range independency, we propose a localization scheme using a mobile anchor node equipped with a directional antenna based on the geometry technique, called LSWD: Localization Scheme for Wireless Sensor Networks using Directional Antenna, this scheme make use of directional antenna concentrates energy on a particularly direction with high gain and narrow covering area. Without increasing hardware and computational complexity, sensor nodes estimate their positions using the minimum number of beacon information. Our localization scheme is verified by network simulation software. The result shows that the proposed localization algorithm has higher accuracy and energy efficiency than other localization schemes. 1.
