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)
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)
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)
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)
