Abstract

Since the mass development of the wireless network, the advancement in wireless communications and micro-electronics element promote the development of wireless sensor networks (WSNs). The sensor nodes of WSNs have the following abilities such as: sensing, computation, and wireless communication capabilities. Hence, WSNs can be used for various application domains. Recently, the localization issue in the WSNs has become an important research topic. In this paper, we propose a location mechanism with mobile reference nodes and Global Positioning System (GPS) to help sensor nodes to calculate the coordinate location information. And then sensor nodes deliver the coordinate location to base station through neighboring sensor nodes. By using this mechanism, we can calculate the coordinate location of the target sensor nodes. And then we can apply this mechanism to track or transfer data packets in the WSNs efficiently.
