Abstract
The sensor nodes of wireless sensor networks (WSNs) have the following abilities such as: sensing, computation, and wireless communication capabilities. Hence, WSNs can be used for various application domains. 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.
