Furthermore, to protect the exchanged data from potential attacks, two levels of security algorithms, including an AES 128 bit with hashing, have been implemented. Besides, this mechanism reduces the channel access congestion thus, it reduces the interference significantly. This approach reduces the primary RFID reader’s burden by receiving data from the clusterheads only instead of reading every tag when they pass by its vicinity. The RFRR reader of the clusterhead collects data from its members, and once it is close to the primary reader, it conveys its data and so on. The smart nodes are grouped in clusters, which are constructed periodically. In this work, we build a network of smart nodes where each node comprises a Radio-Frequency Identification (RFID) tag, reduced function RFID reader (RFRR), and sensors. This study is a small step in this direction, where health information is monitored and collected continuously.
It is evident that IT-based solutions are urgent. Coronavirus pushes all community sectors: government, industry, academia, and nonprofit organizations to take forward steps to stop and control this pandemic.
COVID-19 surprised the whole world by its quick and sudden spread.
