“…Consequently, imply that on-road systems usually require several devices to spread out. As a result, information is scattered and cooperation between devices [13] and between vehicles [14] becomes critical. In these cases, systems are no longer oriented to precisely recognize vehicles but are closer to recognising their behaviour.…”

Detecting and characterising vehicles is one of the purposes of embedded systems used in intelligent environments. An analysis of a vehicle’s characteristics can reveal inappropriate or dangerous behaviour. This detection makes it possible to sanction or notify emergency services to take early and practical actions. Vehicle detection and characterisation systems employ complex sensors such as video cameras, especially in urban environments. These sensors provide high precision and performance, although the price and computational requirements are proportional to their accuracy. These sensors offer high accuracy, but the price and computational requirements are directly proportional to their performance. This article introduces a system based on modular devices that is economical and has a low computational cost. These devices use ultrasonic sensors to detect the speed and length of vehicles. The measurement accuracy is improved through the collaboration of the device modules. The experiments were performed using multiple modules oriented to different angles. This module is coupled with another specifically designed to detect distance using previous modules’ speed and length data. The collaboration between different modules reduces the speed relative error ranges from 1 to 5%, depending on the angle configuration used in the modules.

5G, 6G, and beyond (xG) technologies aim at delivering emerging services with new requirements and challenges, enabling full and hyper mobile connectivity over the world. These beyond 5G networks are expected to ensure better quality of service, very high data rate, improved network security, high capacity, low latency, and low cost. In order to meet these objectives, a number of key enabler technologies have been proposed including massive multiple input multiple output, small cells, mobile edge computing, software defined network, network function virtualization, heterogeneous networks, network slicing, cloud radio access network, ultra-dense network, energy efficiency, and spectrum sharing. Although, the potential interest of these technologies in the network, they opened the door to many security concerns and challenges making the network security one of the primary concerns of the future wireless communication networks. In this article, we investigated the recent advancements on the xG security issues resulted by each key enabler technologies. We analyzed how to secure the network while meeting the emerging promising services, users' demands, and service requirements. We also discussed how the security issues raised by these emerging technologies can be mitigated for efficient and secure communication.

Intelligent Transport System (ITS) has emerged as the most probable technology for improved transport experience more so in environments with high vehicular density. Effective vehicular communication is however hindered by spectrum scarcity due to the already crowded licensed spectrum. This has led to the emergence of Cognitive Radio (CR) systems as a solution to the spectrum scarcity problem. A crucial component in CR is spectrum sensing. Various spectrum sensing techniques including Cyclostationary, Matched Filter, and Energy detection have been proposed and applied with varied outcomes. In this paper, the above mentioned detection techniques are discussed and an improved energy detection based cooperative spectrum sensing scheme is proposed for improved communication in vehicular ad hoc networks (VANET). The proposed scheme showed an improvement in the performance of a network which in turn could lead to more efficient utilization of spectrum.
