I. Introduction
The evolution of Internet of Things (IoT) has been instrumental in changing our daily life beyond our imagination and is the stepping stone for 5G. 5G Research is driven by the Machine-to-Machine (M2M) communication, ubiquitous broadband connectivity, and the tactile internet. The Internet of Things (IoT) would be the predominant driver for the 5G cellular communication networks [1] growth. The reach of IoT spans across every area of lifestyle and business providing the advantages of improved customer engagement, optimization of resources, enhanced connectivity, and efficient data collection from various sources on continuous basis. Efficient access to the 5G networks for the random traffic generated by these IoT devices is a bigger challenge sine these are inactive for longer durations and the periodic internet access is done for trivial or incremental update without human intervention. In 5G networks, hundreds of interconnected IoT devices will be a norm and handling such an exponential growth of sporadic traffic with the existing LTE random access procedures is a herculean task.
