The implementation of wireless sensor networks (WSNs) is central to the operation of smart parking in modern cities. These networks are responsible for monitoring and tracking the occupancy of each parking space in real-time. The WSNs consist of sensor nodes that detect, process, and transmit data to the base station at regular intervals. However, power and communication limitations in these nodes can impact the performance and quality of the network. Early energy depletion, for instance, can shorten the network’s lifespan and necessitate the replacement of sensor nodes. To address these challenges, this paper proposes a WSN routing protocol that employs clustering to build clusters and facilitate multi-hop communication to the base station. This approach offers a robust and efficient algorithm that reduces power dissipation and extends the lifespan of both sensor nodes and the WSN network. Simulation results indicate that this proposed protocol is more energy-efficient, reliable in data transmission, and longer-lasting compared to other protocols commonly used in smart parking management.

This paper investigates the significance of assuming an adaptive Modulation and Coding Scheme (MCS) when scheduling packets of varying sizes in New Radio V2X (NR-V2X). It is envisaged that many existing and future event driven vehicular services will exhibit significant variance in packet sizes, both between applications and within the same application. To ensure a sufficient quality of service, NR-V2X and its predecessor Cellular V2X (C-V2X) must be able to effectively schedule these diverse packet sizes. As such, this paper analyses the impact of fixed vs adaptive MCS selection and shows that assuming an adaptive approach is preferable in all cases, especially when dealing with varying packet sizes. A fixed MCS is commonly assumed in literature and this paper shows that such an assumption can have a large negative performance impact on the MAC layer scheduler. We further evaluate that considering an MCS range exceeding that specified in the current standard is extremely beneficial and evaluate the performance of alternative MCS selection schemes that minimise disruption in the MAC layer grant mechanism. We find that the default standardised MCS selection mechanism still remains preferable.
本文研究了在新无线 V2X（NR-V2X）中调度不同大小的数据包时，假设采用自适应调制和编码方案（MCS）的意义。根据设想，许多现有和未来的事件驱动型车载服务将在数据包大小上表现出显著差异，包括不同应用之间和同一应用内部的差异。为了确保足够的服务质量，NR-V2X 及其前身蜂窝 V2X（C-V2X）必须能够有效地调度这些不同大小的数据包。因此，本文分析了固定 MCS 选择与自适应 MCS 选择的影响，并表明在任何情况下，尤其是在处理不同大小的数据包时，采用自适应方法更为可取。文献中通常假定 MCS 是固定的，本文表明这种假定会对 MAC 层调度器的性能产生很大的负面影响。我们进一步评估发现，考虑超出现行标准规定的 MCS 范围是非常有益的，并评估了其他 MCS 选择方案的性能，这些方案能最大限度地减少 MAC 层授予机制的中断。我们发现，默认的标准化 MCS 选择机制仍然更可取。

Ensuring wireless connectivity for temporary crowded areas is one of the main concerns for wireless operators. Installing a fixed Base Station (BS) with sufficient capacity is inefficient solution that wastes the spectrum resources due to the temporary nature of these areas. Instead, Low-Altitude Platform (LAP) is reported as an efficient alternative, where an aerial entity can carry a BS to serve the desired area during the required time period. However, the optimal location and altitude of the LAP has a significant impact on the attainable performance. In this work, the optimization of both the location and the altitude of LAP that carries a BS of $4times 4$ antenna operating over 28GHz is addressed. The area under investigation is Souq Waqif in Doha (Qatar) which is identified as a seasonal crowded area. Performance evaluation is conducted by the aid of Wireless InSite simulation software in terms of the average received power while considering different types of receive antennas.

The Internet of Things (IoT) applied to agriculture has great potential for improving agricultural production. It involves the use of connected objects such as sensors/actuators, Unmanned Aerial Vehicle (UAV), and robots to enhance productivity and yield while paying attention to the use of pesticides, water, agricultural inputs and Livestock monitoring. Like any computer network, IoT network presents also security problems inducing the false prediction and data analysis in case of network attack. The purpose of this paper consists in analyzing publications on the digital agriculture security study. A database was extracted from Web of Science (WoS) using a defined search string from 2012 to 2023 and processed using the Preferred Reporting Item for Systematic Reviews and Meta-Analysis (PRISMA) method was used to select the most relevant documents on the subject. These documents presented vulnerabilities or attacks on digital agriculture networks and proposed security solutions like cryptography. Search strategy retrieved 227 documents, written by 909 authors and published in 167 sources. The United States of America (USA), India and China were the most productive country with many international collaborations.

Nowadays, several countries have adopted the 5G mm-wave frequency standards such as, China (24.3–27.5GHz, 37–43.5GHz), Japan (27.5–28.8GHz), Sweden (26.5-27.5GHz), Europe (24.25-27.5GHz), the USA (27.5–28.35 GHz and 37–43.5 GHz), and Korea (28GHz) In this contribution, an optically transparent patch antenna with Ultra-wideband characteristics is designed and simulated using HFSS software. Glass serves as the substrate for the proposed antenna while the partial ground plane and the patch element are constructed by using AGH-8 conductor. The patch element is composed of rectangles and two similar circles as to exhibit the UWB characteristics. This proposed antenna is operating from 23.41–45.95 GHz reaching approximately 22.49 GHz of band and has six resonant frequencies 25.7 GHz, 28.24GHz,34.65, 38.64 and 41. 6GHz; this transparent antenna demonstrates a gain of approximately 5 dB for the six operating frequencies.

Recently, unmanned aerial vehicles (UAVs) or drones are gaining more attention owing to the versatile use cases that they can support. They are also considered as an integral part of the sixth generation (6G) and beyond networks. However, with increasing UAVs, there comes a requirement to regulate their movement in the airspace. Such regulations can provide better management and mitigate safety and security concerns. As such, direct remote identification (DRI) is one approach which allows authorities to identify any drone in the airspace and provides information about drones in flight, such as the drone’s identity, location, altitude and its control station or take-off location. Although, there has been numerous research performed on DRI and respective topics, but none of them proposed usage of commercial-off-the-shelf (COTS) wireless radio modules along with DRI. To overcome this problem, we evaluate DRI using various COTS under the Wi-Fi and Bluetooth use cases and later presented a comparative analysis of long-range frequency and power consumption for such COTS modules. At last, we also shed some light on the security aspects.

Digital predistortion (DPD) technology linearizes power amplifiers (PAs) so that they can operate in a high-efficiency region. The estimation of the coefficients for the DPD model is therefore crucial but resource-intensive. Meanwhile, spiking neural networks (SNNs) are considered to have advantages in energy efficiency due to their ability to closely mimic the activity of human brain neurons. In this paper, we introduce a novel approach to estimate the coefficients of the DPD model. This approach uses a regressor with a structure that combines SNN and artificial neural network (ANN), along with two different loss functions. The proposed method is evaluated with datasets measured on a strongly nonlinear PA with a peak output power of 200W. The results show that we can achieve a good fit of generalized memory polynomial (GMP) based DPD coefficients with the proposed method. To the best of our knowledge, this is the first time that the SNN is used in computing DPD coefficients. This study offers valuable insights into the potential of SNN-based wireless communication technologies.

Software-Defined Networking (SDN) is a networking paradigm that separates the network’s control plane from the data plane, providing centralized and programmable management of network resources. SDN has been increasingly used to enhance load balancing in cloud computing environments, as it allows for dynamic, efficient, and automated traffic distribution across the network. SDN controllers can make real-time load balancing decisions based on network conditions and application requirements. This paper focuses on recent research concerning the utilization of SDN to enhance load balancing in cloud computing. The paper categorizes these contributions according to various properties of SDN, notably including Dynamic Traffic Engineering, Centralized Load Balancing Decisions, Application-Aware Load Balancing, Multi-Path Load Balancing, Load Balancing for Virtualized Environments as well as QoS-Based Load Balancing.

In this paper, we investigate the physical layer security of a two-user multiple-input-multiple-output (MIMO) non-orthogonal multiple access (NOMA) with transmit antenna selection (TAS) in mixed radio frequency (RF) and free-space optical (FSO) communications. Specifically, the uplink RF transmissions between the users and a relay node undergo a Nakagami-m fading while the FSO link between the relay node and the destination node experiences a gamma-gamma fading. Considering this model, the statistical features constituted of the probability density function (PDF) and cumulative distribution function (CDF) are obtained in closed form. The derived expressions are subsequently used to obtain the analytical expressions of the secrecy outage probability (SOP) and the probability of the strictly positive secrecy capacity (SPSC). Monte Carlo simulations are provided to verify the accuracy of the proposed analytical framework.

Monte Carlo simulations are provided to verify the accuracy of the proposed analytical framework.","PeriodicalId":505542,"journal":{"name":"2023 6th International Conference on Advanced Communication Technologies and Networking (CommNet)","volume":"7 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139183740","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
