The Internet of Things (IoT) is an essential part 5G, Beyond-5G (B5G), and 6G systems; it has several applications in two the principal 5G use cases, namely ultra-reliable low-latency communications (URLLC) massive machine-type (mMTC), their successors within B5G 6G: extreme communication (eURLLC) ultra-massive (umMTC). IoT systems, which are characterized by narrow bandwidths, have stringent requirements owing to specific nature cases. purpose this study investigate jointly optimize energy...
Narrowband Internet of Things (NB-IoT) is a cellular IoT communication technology standardized by 3rd Generation Partnership Project (3GPP) for supporting massive machine type and its deployment can be realized simple firmware upgrade on existing long term evolution (LTE) networks. The NB-IoT requirements in terms energy efficiency, achievable rates, latency, extended coverage, make the resource allocation, limited bandwidth, even more challenging problem w.r.t. to legacy LTE. done with...
In this paper we evaluate the performance of fifth generation new radio (5G NR) based positioning under realistic conditions model for cooperative connected automated mobility (CCAM) scenarios. We benchmark using 3GPP release 16 proposed reference signal (PRS), in 5G NR mobile networks. Time difference arrival (TDoA) methods is one widely used method which localization. Simulation results are showing that line-of-sight (LOS) conditions, desired accuracy achievable various CCAM use-cases....
The fifth-generation (5G) and beyond 5G (B5G) wireless networks introduced massive machine-type communications (mMTC) to cope with the growing demand of Internet Things (IoT) applications. However, heterogeneous characteristics IoT diverse quality service (QoS) requirements may lead severe interference that could degrade expected QoS cellular ecosystem. Therefore, this article studies impact caused by mMTC connections. We theoretically model intercell (ICI) minimization problem for existing...
Internet of things (IoT) and device to (D2D) communications are among the novel promising technologies in current releases 4G they will play a fundamental role next generation 5G as well. In this paper, it is investigated impact allocation strategies that take into account mutual interference D2D Narrow-Band IoT terminals cellular transmitting same resource block. multi-cellular downlink context, proposed approach analysis can serve also an efficient criterion for selecting target SINR,...
The problem of weighted throughput maximization is generally non convex and computationally intense. A solution, known as MLFP-based power allocation or MAPEL algorithm, transforms the into a multiplicative linear fractional programming then uses method based on polyblock outer approximation. In this paper, we are going to use some techniques for reducing computational time, in particular regarding minimum rate constraint optimization problem. Furthermore, introducing, procedure, water...
Vehicular communication and autonomous driving are currently very important research topics. As a result; the study of V2X became essential. In this paper we have started by briefly introducing new radio 5G sidelink, then performed computer simulations in order to performance V2X, terms data rate, packet error rate latency. The impact transmitted power distance, between transmitter receiver, on those indicators is focus study. Particularly effect power; since consumption energy efficiency...
In this paper, the goal is to reduce Multi-access Edge Computing (MEC) service placement and migration delay for Connected Automated Vehicles (CAV) by using precise position of vehicle. To process delay, must start before vehicle reaches future serving node. Thus, an AI position-based scheme proposed predict candidate nodes migration. Real-time positioning data acquired from RTK-GNSS measurements campaign. The obtained imbalanced raw treated used with prediction scheme, resulting accuracy up...
Uplink conventional power control techniques in systems with frequency reuse one have some limitations, typically regarding the tradeoff between average throughput of users at cell center and edge. Moreover, main drawbacks is excess use power. From our point view, reasons for this waste practice giving all same target SINR process. Since there exists a rate limit cell, depending on their positions, Hybrid Power Control (HPC) technique introduced here order to overcome these limitations...
In this paper, we propose an inter-cell interference (ICI) minimization scheme for uplink transmission in the narrowband internet of things (NB-IoT) systems.
