Enabling ubiquitous sensing with RFID

There are various methods of automatic identification techniques. But among these methods Radio Frequency Identification (RFID) has become an excellent and reliable method for electronic identification, data capture, control, track, and inventory items using RF communication. Today RFID is having a very broad use but most of the time such systems are invisible or are not recognized by the users. RFID is replacing bar-code-based identification mechanisms, as communication between a reader and a tag( which form the RFID) is not limited by the requirement of “Line of sight” reading and each tag has a unique ID. RFID technology can be utilized to effectively optimize multiple business processes through the improvement, the automation or even the elimination of existing processes, and the emergence of new processes called intelligent processes or smart processes, which are automatically triggering actions or events. In the present work several RFID based systems have been designed and simulated. The first one is an automatic Home/Office network controller and the second one is an automatic weight monitoring system and so on. The energy consumption can be significantly reduced by designing a Home/Office network controller which detects non-operational electronic systems in a room (Light/Air conditioner) during a particular span of time and automatically turns off these systems thereby conserving energy. In the weight controlling mechanism the RFID based control unit automatically prevents overloading as well as under loading of vehicles in loading stations. Other applications have been described in a brief manner.
