Active RFID System with Wireless Sensor Network for Power

Radio frequency identification (RFID) and wireless sensor networks (WSNs) are complementary technologies that reduce power consumption. Battery-operated WSNs suffer from issues related to power consumption and latency. WSN already in the market use either duty cycling or wake-up radio mechanisms. The research puts forth ZigBee-based RFID that employs active (battery-powered) tags based on a new deep-sleep mechanism. This mechanism reduces the tags’ power consumption as a whole. To best show the system’s efficacy, different parameters are in place to execute and analyse. All the testing is done in realistic indoor network settings and in turn benchmarked against calculated predictions. A comparison is done between conventional duty-cycle tag methods of protocol with the sleep-mode protocol. The findings indicate that the sleep-mode protocol is more energy efficient with consumption being 98% lower than the IEEE802.15.4 tag.
