Abstract
The Internet of Things (IoT)-centric concepts like augmented reality, high-resolution video streaming, self-driven cars, smart environment, e-health care, etc. have a ubiquitous presence now. These applications require higher data-rates, large bandwidth, increased capacity, low latency and high throughput. In light of these emerging concepts, IoT has revolutionized the world by providing seamless connectivity between heterogeneous networks (HetNets). The eventual aim of IoT is to introduce the plug and play technology providing the end-user, ease of operation, remotely access control and configurability. This paper presents the IoT technology from a bird’s eye view covering its statistical/architectural trends, use cases, challenges and future prospects. The paper also presents a detailed and extensive overview of the emerging 5G-IoT scenario. Fifth Generation (5G) cellular networks provide key enabling technologies for ubiquitous deployment of the IoT technology. These include carrier aggregation, multiple-input multiple-output (MIMO), massive-MIMO (M-MIMO), coordinated multipoint processing (CoMP), device-to-device (D2D) communications, centralized radio access network (CRAN), software-defined wireless sensor networking (SD-WSN), network function virtualization (NFV) and cognitive radios (CRs). This paper presents an exhaustive review for these key enabling technologies and also discusses the new emerging use cases of 5G-IoT driven by the advances in artificial intelligence, machine and deep learning, ongoing 5G initiatives, quality of service (QoS) requirements in 5G and its standardization issues. Finally, the paper discusses challenges in the implementation of 5G-IoT due to high data-rates requiring both cloud-based platforms and IoT devices based edge computing.

D. FEATURES EMPLOYED IN 5G NETWORKING LAYER TO SUPPORT 5G-IoT These network architectures previously hardware-based, will have to manage the exponentially growing traffic, deployment/induction of new nodes, efficient network forwarding infrastructures and the network expansion flexibility. FEATURES EMPLOYED IN 5G NETWORKING LAYER TO SUPPORT 5G-IoT These network architectures previously hardware-based, will have to manage the exponentially growing traffic, deployment/induction of new nodes, efficient network forwarding infrastructures and the network expansion flexibility To achieve these objectives, different network-enabling technologies are developed which are emerging. On physical and network layers, AI based optimization algorithms could facilitate dynamic spectrum management, structuring of huge data, integration of heterogeneous devices, ultradensification of devices, IoT nodes interoperability, and improved battery life [96]. The integration of 5G with IoT and AI has a huge impact on business by making predictions using available data and taking control decisions for enhancing the technology to improve quality-of-life
