%X <p>Under the circumstances that wireless sensor network (WSN) nodes are deployed in a vast region and the node density is low, the existing node location algorithms are not optimum selections. A WSN node self-locating algorithm which utilized the directivity of smart antenna is proposed. There are two types of nodes in the objective network of the means. The first type is central node that equipped with global position system (GPS) unit and smart antenna. The second type is normal node that equipped with high frequency crystal oscillator. Normal node can support time of arrival (TOA) based ranging. With the help of directional locating signal sent by central node,a normal node can estimate the angle and distance between itself and the central node, and determine its position combining the angle and TOA based ranging result. Analysis and experimental results show that the proposed algorithm can provide fine location accuracy with relative low cost and low complexity.</p>
