I. INTRODUCTION
Due to the marked shift to large-scale computing, current research efforts have engrossed in developing low-cost wireless sensing solutions. Wireless technologies, including Wireless Local Area Networks (WLAN), ZigBee, and Bluetooth, require large amounts of power to function naturally, requiring significant cycle complexity. It contributes to the high cost of the whole system and the limited life of the device. In this case, the radio frequency identification (RFID) technology provides a cost-effective and long-term solution [1].
