摘要：Monitoring and tracking systems utilizing Wireless Sensor Networks (WSN) are in the core of Ubiquitous Computing research. The evolving computing field of Internet of Things (IoT) incorporates concepts from the ubiquitous computing paradigm. Many IoT potential applications involve monitoring and tracking of these “things”. In this paper, we present the design and implementation of a scalable monitoring system based on WSN. The utilized “sensors” in the proposed prototype are Radio-Frequency Identification (RFID) and Global Positioning System (GPS) modules. We refer to the system as WiSe-SMS (Wireless Sensor Network-based Scalable Monitoring System). The goal is to establish WiSe-SMS in the literature as a framework to implement relevant scalable IoT systems. WiSe-SMS has the potential to be scaled to a large number of monitored objects while tracking their historical locations. In this paper we present the details of the WiSe-SMS design and implementation of its hardware and software components. The system prototype is tested and experimental results are discussed and analyzed.
