Method of centralized resource allocation in virtualized small cells network with IoT overlay

In this paper, the centralized dynamic resources allocation method for LTE networks is proposed. This method provides dynamic resource allocation according to the users' requirements by small cell virtualization and resource reusing to avoid co-channel interference. The additional novelty of our proposed approach is the additional IoT (Internet of Things) slice overlaying the traditional cellular coverage. This slice provides the transmission of the IoT data by using resource elements, which have not been utilized by mobile users. Thus, important IoT data is transmitted in opportunistic manner, while maintaining the quality of service requirements and throughput demands of mobile users. Resource allocation in proposed method is handled by centralized controller based on C-RAN (cloud radio access network) architecture. Proposed approach improves the bandwidth utilization of the small cells network.
