The Internet of Things (IoT) concept is being widely presented as the next revolution toward massively distributed information, where any real-world object can automatically participate in the Internet and thus be globally discovered and queried. Despite the consensus on the great potential of the concept and the significant progress in a number of enabling(More)
Despite the popularity of current radio frequency identification (RFID) and wireless sensor networks (WSN), current research fails to propose the global vision that is needed for truly pervasive computing. In this paper we introduce our effort to build a global standard infrastructure for WSN and RFID based on the EPCglobal standard architecture framework.(More)
Deployment of embedded technologies is increasingly being examined in industrial supply chains as a means for improving efficiency through greater control over purchase orders, inventory and product related information. Central to this development has been the advent of technologies such as bar codes, Radio Frequency Identification (RFID) systems, and(More)
In this paper, an efficient target classification and fusion scheme for wireless sensor networks (WSNs) is proposed and evaluated. When a classification algorithm for WSN nodes is designed, parametric approaches such as Gaussian mixture model (GMM) should be more preferred to non-parametric ones due to the hard limitation in resources. The GMM algorithm not(More)
Pervasive computing environments have traditionally used distributed sensors to gather user context. EPC (electronic product code) information extracted from RFID tags could additionally provide identification information associated with that context. However, the process of matching sensor and RFID information around the same context is not a trivial task.(More)
With low-power consumption, small code and data size, evolvability as design criteria, we develop an evolvable operating system (EOS) for wireless sensor network applications. The EOS provides memory space efficient thread management, collaborative thread communication model and network stack. It also supports power management of microcontroller and radio(More)
