Optimal Radio Resource Allocation in Small Cells for a Massive IoT Network: An mMTC Perspective

The growing number of resource-restrained Machine-Type Communications (MTC) gadgets such as IoT devices are generating challenges toward obtaining miscellaneous communication requirements in ultra-dense and dynamic wireless environments. Among distinct application cases the forthcoming 5G cellular network is expected to assist applications such as massive MTC (mMTC) that brings the infrequent technical challenge of assisting a massive or large number of MTC gadgets or devices in wireless networks. The imminent need for mMTC led to the achievement of the state-of-the-art IoT vision across a range of communications system with varied service requirements. To serve such massive IoT infrastructure the optimal deployment of small cells will be a crucial approach. Since small cells are highly capable to serve high-density or ultra-dense networks. The paper, therefore, performed research on assigning optimal network resource namely bandwidth allocation considering the requirement by a massive IoT network. Moreover, the researchers developed an easy-to-implement algorithm regarding the optimal bandwidth allocation to extend the research on small cells and mMTC.
