“…The coverage area for a BS is large and a BS is expected to serve many users. Conversely, the coverage area for a hotspot is small and the number of users served is low [7]. In this case, users associated with BSs can be considered as PUs, and users in hotspot areas as NUs.…”

A heterogeneous network (HetNet) is a mix of macrocell base stations (MBSs) underlaid by a diverse set of small cell base stations (SBSs) such as microcells, picocells and femtocells. These networks are employed to enhance network capacity, improve network coverage, and reduce power consumption. However, HetNet performance can be limited by the disparity of power levels in the different tiers. Further, conventional cell association approaches cause MBS overloading, SBS underutilization, excessive user interference and wasted resources. Power control and cell association (CAPC) should be determined based on user priority, channel condition and BS traffic load. However, ensuring priority user (PU) requirements while satisfying as many normal users (NUs) as possible is not considered in existing power control algorithms. In this paper, prioritized CAPC is proposed to solve the load balancing problem between MBSs and SBSs and meet the needs of all PUs. Performance results in Additive white Gaussian noise (AWGN) and Rayleigh fading channels are presented which show that the proposed scheme is a fair and efficient solution which reduces power consumption and has faster convergence than other CAPC schemes.

Industry 4.0 applications foster new business opportunities, but they also pose new and challenging requirements, such as low latency communications and highly reliable systems. They would likely exploit novel wireless technologies (5G), but it would also become crucial using architectures that appropriately support them. In this sense, the combination of fog and cloud computing represents a potential solution, since it can dynamically allocate the workload depending on the specific needs of each application. In this paper, our main goal is to provide a highly reliable and dynamic architecture, which minimizes the time that an end node or user, spends in downloading the required data. In order to achieve this, we have developed an optimal distribution algorithm that decides the amount of information that should be stored at, or retrieved from, each node, to minimize the overall data download time. Our scheme is based on various parameters and it exploits Network Coding (NC) as a tool for data distribution, as a key enabler of the proposed solution. We compare the performance of the proposed scheme with other alternative solutions, and the results show that there is a clear gain in terms of the download time.

“…In 5G systems, industrial data services are considered in two main usage scenarios, i.e., mMTC and URLLC, which provide connections for the long range IoT coverage and mission-critical applications, respectively [83]. The 5G air interface, known as 5G new radio (NR), has implemented new techniques in its physical (PHY) layer and MAC layer to support machine-typed communications [98]. 5G NR defines more dedicated radio resources, such as the sub-millisecond time resolution in the transmission time interval (TTI) and OFDM symbol durations.…”

Wireless Network Design for Emerging IIoT Applications: Reference Framework and Use Cases

et al. 2019

Industrial Internet of Things (IIoT) applications, featured with data-centric innovations, are leveraging the observability, control, and analytics, as well as the safety of industrial operations. In IIoT deployments, wireless links are increasingly used in improving the operational connectivity for industrial data services, such as collecting massive process data, communicating with industrial robots, and tracking machines/parts/products on the factory floor and beyond. The wireless system design for IIoT applications is inherently a joint effort between operational technology (OT) engineers, information technology (IT) system architects, and wireless network planners. In this paper, we propose a new reference framework for the wireless system design in IIoT use cases. The framework presents a generic design process and identifies the key questions and tools of individual procedures. Specifically, we extract impact factors from distinct domains including industrial operations and environments, data service dynamics, and the IT infrastructure. We then map these factors into function clusters and discuss their respective impact on performance metrics and resource utilization strategies. Finally, discussions take place in four exemplary IIoT applications where we use the framework to identify the wireless network issues and deployment features in the continuous process monitoring, discrete system control, mobile applications, and spectrum harmonization, respectively. The goals of this work are twofold: 1) to assist OT engineers to better recognize wireless communication demands and challenges in their plants, 2) to help industrial IT specialists to come up with operative and efficient end-to-end wireless solutions to meet demanding needs in factory environments.
