Abstract
Fifth generation (5G) cellular networks provide high speed services to the users in multimedia applications. Generally, a 5G network consists of large (Macro) and small (Femto/Micro) cells to provide variety of services to the User Equipments (UEs), having different requirements. Heterogeneous Networks (HetNets) contain small cells in the coverage region of macro cells. Resource allocation (RA) is a process of allocating available resources to the users according to their Quality of Service (QoS) demands. But resource allocation in 5G HetNets become challenging due to Interference among cells and Handoff. As Internet of Things (IoT) edge devices have dynamic traffic requirements, it will be difficult to allocate resources for them. In this paper, we propose an Intelligent RA Decision (IRAD) which is formulated and analyzed. In IRAD, Deep Learning based Encoder with Neural Network (DL-ENN) architecture is designed to classify the end IoT devices depending on their QoS requirements and traffic characteristics. From the output of classified results, optimum RA decisions are made to each device. In RA strategy of femtocells, the transmit power and allocated resources of each femtocell user are optimized such that minimum data rate requirements of femtocell users are satisfied and interference power from femtocells to the macro cells is reduced. The Improved Chicken Swarm Optimization (ICSO) algorithm is used for optimized RA decision to small cell users. By simulation results, we show that the proposed IRAD technique provides maximum resource utilization and throughput with reduced packet loss ratio.
