Wireless sensor networks (WSN) for its low cost, easy deployment and affordable services are being used in different applications such as environmental monitoring, health, safety, among others. Recently, it has increased its use in localization and tracking problems. In a WSN, sensor node is associated with a coordinator node to form a Personal Area Network (PAN). In localization and tracking problems when sensor nodes are mobile there are problems when moving from one PAN to another, as they must execute a handover mechanism which is complicated by the limited computing capabilities that they have. In this paper, a WSN architecture for locating and tracking that eliminates the need for handover when a sensor node moves through the WSN is proposed. The proposed architecture considers two PAN conformations, one that is responsible for communicating the sensor nodes with nodes access point (AP) and the other forming a backbone network between the AP and the coordinator node. The results obtained after developing experiments in a real environment support the operation and benefits of the proposed architecture. © 2016 IEEE.
