Physical layer aspects of wireless IoT

Abstract

Internet of Things (IoT) is receiving important attention from industries and research communities as an important enabler for Fifth Generation (5G) of wireless communications. It has a wide range of application areas ranging from telecommunications to building smart communities, which will improve various aspects of our everyday lives. However, designing IoT-enabled wireless networks which can deliver a variety of services with desirable quality of experience under energy/resource constrained practical wireless scenarios is crucial. One of the important aspects here is to design the physical (PHY) layer of IoT-based wireless systems considering the practical constraints of energy efficiency, spectral efficiency, cost-effectiveness, and Quality of Service (QoS). In this regard, this paper provides an overview of the related existing works from the PHY layer perspective. Various PHY layer enabling techniques are highlighted and the PHY layer aspects of different IoT enabled wireless networks are discussed. Finally, it provides some interesting research issues and future recommendations.

Device Grouping for Fast and Efficient Channel Access in IEEE 802.11ah Based IoT Networks

“…The future of networking is not only bounded with people but also is related to the integration of all objects, media and services, thus creating the Internet of Everything (IoE) [17]. The IoE connects the people, communicating objects or things, processes, and data in an effective manner to provide the ubiquitous services [18]. In this regard, we consider a large-scale IoT scenario composed of N number of stations deployed over a circular area of radius 1 km as depicted in Fig.…”

Secure and Access Control Data Monitoring in Vehicular Ad Hoc Network

“…At present, with the quick advancement of the city, individuals are increasingly more necessity on transportation, confronting the standardization issue, for example, city traffic clog, traffic wellbeing, traffic association, etc, the conventional perspective has been notable take care of these issues .With the fast improvement of science and innovation, for example, geographic data, correspondence, sensor and PC innovation, Internet-of-Vehicles (IoV) has drawn extraordinary research and industry consideration. The blend of data from sensors locally available various vehicles and on the framework through correspondence frameworks will at last yield traffic sensor systems opening up an absolutely new range of functionalities with uncommon benefits [2]. Above all else, agreeable detecting and helpful move arranging will extensively improve traffic security.…”

Latency Minimization in Wireless IoT Using Prioritized Channel Access and Data Aggregation

“…Various application requirements have brought many challenges to design more efficient and reliable industrial IoT networks. The main challenges in industrial IoT networks include low latency, low per node energy consumption, reliability, and secure data transmissions to the application servers [5]. Out of these, IoT network latency has been considered as one of the most critical issues in industrial automation and control sub-systems.…”

“…The main network parameters that affect the system delay are node density, data rate, and energy per node, processing power, routing protocol and Medium Access Control (MAC) protocol [6]. To deal with the latency issue, an IoT network must be designed to meet the real-time requirements of the aforementioned application scenarios [5].…”
