In this work we present an IC architecture of RF energy harvesting for wireless sensors networks. By analyzing a probabilistic approach used for modeling the possible amount of Global System for Mobile Communication (GSM) energy that could be harvested, an IC system with a 0.18μm CMOS SMIC technology has been designed and optimized at 90 and 900 MHz. so to take advantage of the GSM and FM radio radiated...
Radio frequency identification (RFID) technology is recently intensively investigated as an effective solution for the next generation communication services in business processes. In this paper we propose an RFID-based location tracking system for distributed offices based on session initiation protocol (SIP). The proposed system is compatible with EPCglobal standard, but extension with SIP at application...
RFID are becoming increasingly popular and are widely used in many applications. Tags can be used for environment and habit monitoring, healthcare applications, home automation and pedestrian or vehicle traffic control. This paper describes the method of building a robust N-state Markov model that describes visitor's behavior in a gallery room. The built model can be used in planning of exhibitions,...
