Abstract: In wireless communications, different collision avoidance medium access control (MAC) protocols are available to avoid contention, but none of them are accepted as standard protocols to fulfil the requirements of the internet of things (IoT). So, there is a need for well-defined MAC protocols to optimise the channel access mechanism. Therefore, this paper presents the fundamentals of IoT, types of collisions, features of IoT-based communication technologies, and a comparative study of collision avoidance MAC protocols in IoT. This paper first outlines the system model of IoT networks based on a comprehensive study of the reported literature. Following that, types of collisions are discussed. Further, we have provided a comprehensive study of ALOHA, CSMA, CSMA/CA, and hybrid MAC protocols, issues in MAC protocols, and their state-of-the-art solutions to avoid collisions and to provide higher throughput. Finally, future research direction for IoT has been highlighted to underline potential real-time IoT applications.
