Abstract: Reconfigurable intelligent surfaces (RISs)-enabled high-frequency wireless systems will support reliability and data rate-hungry applications. However, misalignment and turbulence affect such systems. Most performance assessments of RIS-empowered wireless systems ignore these phenomena. This motivates the…
Abstract: Network technologies are evolving rapidly. The increasing volume of transmitted data (video, data, VoIP, etc.), network growth, and inter-network traffic are forcing manufacturers to create more powerful and “smart” devices that use new data…
Abstract: An exhaustive search of all candidate beam pairs for millimeter-wave links in a vehicular scenario cannot be completed within short contact times. We use LiDAR, camera, and GPS data to speed up beam selection….
Abstract: Vehicles must send safety and non-safety messages quickly and without loss in the intelligent transport system. SCH channels in multi-channel MAC have frequency range, power limit, distance covered, and channel performance. These channel properties…
Abstract: Edge caching has been studied for vehicular ad hoc networks (VANETs) to improve infotainment application efficiency and reliability. We propose a two-layer distributed content caching scheme for VANETs using vehicle and roadside unit (RSU)…
Abstract: VANET research is difficult but active. It offers ITS, road traffic monitoring, traffic flow, and road safety applications. Fixed silent segments make emergency data collection difficult. This issue may delay critical ITS operations. This…
Abstract: At mm-wave and sub-THz bands, 5G New Radio (NR) and beyond mobile cellular systems should integrate efficient connectivity, positioning, and sensing functions. This article discusses radio-based sensing and environment mapping for user equipment (UE)….
Abstract: Intelligent Transport Systems research now includes Vehicular Ad-hoc Networks (VANET). Urban vehicles constantly move at different speeds, changing the network topology. Routing protocols’ performance when sending data between vehicles is the main issue in…
Abstract: This project examines a wireless-powered UAV communication network with backscatter and caching. We assume a self-energized UAV with a cache memory is deployed as a flying backscatter device (BD), the UAV-enabled BD (UB), to…
Abstract: Because of their widespread use in real-world problems, solving linear programming (LP) and nonlinear programming (NLP) problems is important. NLPs have no unified global optimum. However, the simplex algorithm, which has dominated LPs for…
Abstract: Intelligent vehicles with Vehicle-to-Vehicle (V2V) and Vehicle-to-Road Side Unit (V2R) communications form Vehicular Ad hoc Networks (VANETs). This paper proposes a model to predict network traffic using road traffic parameters. The model predicts network…
Abstract: Radar, wireless, and underwater communications depend on source localization. TOA, TDOA, AOA, and RSS-based localization methods are the most popular. In source localization applications, sensor placement is crucial because the Cramér-Rao lower bounds (CRLB)…
