The COVID-19 pandemic has seriously threatened the health and well-being of humanity. Contact tracing (CT) as an important non-pharmaceutical intervention is essential to contain the spread of such an infectious disease. However, current CT solutions are fragmented with limited use of sensing and computing technologies in an evolving framework. These problems can be solved well with the use of Internet of Things (IoT) technologies. Therefore, we need to review the principle, motivation and architecture of a generic IoT-based CT system (IoT-CTS). A new architecture for IoT-CTS solutions is offered taking into account peer-to-peer and object-to-peer contact events, as well as discussion of key topics, such as an overview of applicable sensors for the needs of CT resulting from Methods of transmission of COVID-19. The proposed IoT-CTS architecture aims to holistically utilize essential detection mechanisms with analysis of widely adopted privacy preservation techniques. Through the use of generic peer-to-peer and object-to-peer sensors based on proximity and environment detection mechanisms, infectious cases with self-directed strategies can be effectively reduced. Some open research directions are presented at the end.
