Scope of machine learning applications for addressing the challenges in next‐generation wireless networks

Abstract

The convenience of availing quality services at affordable costs anytime and anywhere makes mobile technology very popular among users. Due to this popularity, there has been a huge rise in mobile data volume, applications, types of services, and number of customers. Furthermore, due to the COVID‐19 pandemic, the worldwide lockdown has added fuel to this increase as most of our professional and commercial activities are being done online from home. This massive increase in demand for multi‐class services has posed numerous challenges to wireless network frameworks. The services offered through wireless networks are required to support this huge volume of data and multiple types of traffic, such as real‐time live streaming of videos, audios, text, images etc., at a very high bit rate with a negligible delay in transmission and permissible vehicular speed of the customers. Next‐generation wireless networks (NGWNs, i.e. 5G networks and beyond) are being developed to accommodate the service qualities mentioned above and many more. However, achieving all the desired service qualities to be incorporated into the design of the 5G network infrastructure imposes large challenges for designers and engineers. It requires the analysis of a huge volume of network data (structured and unstructured) received or collected from heterogeneous devices, applications, services, and customers and the effective and dynamic management of network parameters based on this analysis in real time. In the ever‐increasing network heterogeneity and complexity, machine learning (ML) techniques may become an efficient tool for effectively managing these issues. In recent days, the progress of artificial intelligence and ML techniques has grown interest in their application in the networking domain. This study discusses current wireless network research, brief discussions on ML methods that can be effectively applied to the wireless networking domain, some tools available to support and customise efficient mobile system design, and some unresolved issues for future research directions.

On-Demand Centralized Resource Allocation for IoT Applications: AI-Enabled Benchmark

“…Traditional machine learning is widely used in resource allocation management in IoT networks [16,17], including resource scheduling and traffic classification. For instance, Junaid et al [1] proposed a resource-efficient clustering framework for social IoT applications that performs geographic text clustering hierarchically without significantly reducing clustering quality.…”

Deep learning for SDN-enabled campus networks: proposed solutions, challenges and future directions

“…Although the combination of SDN and DL shows great success in solving the automation problem in campus networks, there are still challenges that limit their full utilization. Samanta et al (2022) and Zhang et al (2020) point out five issues that slow down deep learning implementations: black box nature, limited resources, data volume, increased number of layers to train and adversarial properties of DL models. Another study by Liao et al (2020) insists on preparing a representative dataset to create successful models.…”

Critical Failure Mode Determination of Steel Moment Frames by Plastic Analysis Optimization Principles

“…To deal with this problem, artificial intelligence (AI) can be an appropriate choice. Generally, machine learning and deep learning approaches are two branches of AI, where numerous studies in different areas exist in the literature [19,20]. Artificial intelligence (AI) and machine learning (ML) are being increasingly used in structural engineering applications for tasks such as structural analysis, design optimization, and predictive maintenance [21][22][23][24].…”
