The dramatic growth of data traffic during the past decade has challenged wireless networks to provide new mechanisms support such demand. Fast deployable supported by Unmanned Aerial Vehicles (UAV) are a promising solution, especially in crowded scenarios with high peaks traffic. Nevertheless, mounting Base Station (BS) on UAVs (UAV-BSs) raises several challenges like saturation backhaul (BH) ...

This article studies massive access in cell-free multi-input multi-output (MIMO)-based Internet of Things and solves the challenging active user detection (AUD) channel estimation (CE) problems. For uplink transmission, we propose an advanced frame structure design to reduce latency. Moreover, by considering cooperation all points (APs), investigate two processing paradigms at receiver for acce...

An edge computing offloading strategy was proposed with the goal of addressing issue low efficiency and service quality in multi-service multi-user intersections networked vehicles. This took into account all relevant factors, including matching users nodes, ratio, bandwidth power resource allocation, system energy consumption. It is mainly divided 2 tasks: (1) Service node selection: A fuzzy l...

Fifth-generation (5G) mobile networks fulfill the demands of critical applications, such as Ultra-Reliable Low-Latency Communication (URLLC), particularly in automotive industry. Vehicular communication requires low latency and high computational capabilities at network’s edge. To meet these requirements, ETSI standardized Multi-access Edge Computing (MEC), which provides cloud computing addres...

Here, we consider the problem of jointly optimizing users' offloading decisions, communication and computing resource allocation in a sliced multi-cell mobile edge (MEC) network. We minimize weighted sum gap between observed delay at each slice its corresponding requirement, where weights set priority slice. Fractional form objective function, discrete subchannel allocation, considered partial ...

Edge computing is a new paradigm which distributes tasks to edge networks for processing, it provides effective support various mobile applications meet their rapid response requirement. Unmanned Aerial Vehicle (UAV) has been widely used in emergency rescue, mapping, etc., with the advantages of flexible deployment and movement. However, on one hand, will be terminated when battery energy exhau...

Cloud computing technology is providing businesses, be it micro, small, medium, and large scale enterprises with the same level playing grounds. Small and Medium enterprises (SMEs) that have adopted the cloud are taking their businesses to greater heights with the competitive edge that cloud computing offers. The limitations faced by (SMEs) in procuring and maintaining IT infrastructures has be...
