Vehicular Ad-Hoc Networks (VANETs) are a sub form of Mobile Ad-Hoc Network that provide communication among vehicles (V2V) and vehicles to infrastructure (V2I). VANETs have been developed to offer reliable and efficient services on the roads. These services include safety applications (collision warning), and non-safety applications (video and voice). The IEEE 802.11p is an extension of the IEEE 802.11 standard to support wireless access into vehicular environments. However, the IEEE 802.11p standard does not perform well for VANETs under high traffic load and mobility. The is owing to the nature of contention-based channel access mechanism in IEEE 802.11p sharing a common radio frequency. The work in this paper presents a new scheme to improve the channel access coordination of 802.11p for V2I communication under high traffic and mobility. This scheme adaptively adjusts the contention window (CW) based on the times (deadlines) that the vehicles are about to exit the RoadSide Unit (RSU) coverage area. Priority service is given to vehicles with shorter deadlines and vice versa. The Network Simulator (NS-2) v.2.35 is used for simulation. According to simulation results, our proposed scheme outperforms the existing scheme in terms of throughput, packet loss ratio and packet delivery.
车辆自组织网络(vanet)是移动自组织网络的一个子形式,提供车辆之间(V2V)和车辆到基础设施(V2I)的通信。开发VANETs是为了在道路上提供可靠和高效的服务。这些服务包括安全应用(碰撞警告)和非安全应用(视频和语音)。IEEE 802.11p是IEEE 802.11标准的扩展,以支持无线接入车辆环境。然而,IEEE 802.11p标准在高流量负载和移动性下对vanet表现不佳。这是由于IEEE 802.11p中基于争用的信道访问机制共享一个公共无线电频率。本文提出了一种改进802.11p高流量、高移动性V2I通信信道接入协调的新方案。该方案基于车辆即将离开RSU覆盖区域的时间(截止日期)自适应调整争用窗口(CW)。优先服务给予期限较短的车辆,反之亦然。使用Network Simulator (NS-2) v.2.35进行仿真。仿真结果表明,本文提出的方案在吞吐量、丢包率和数据包传输方面都优于现有方案。

Hybrid Evolutionary Approach in Feature Vector for Ransomware Detection 勒索软件特征向量混合进化检测方法
Nawaf Aljubory, B. Khammas
Ransomware is one of the most serious threats which constitute a significant challenge in the cybersecurity field. The cybercriminals use this attack to encrypts the victim's files or infect the victim's devices to demand ransom in exchange to restore access to these files and devices. The escalating threat of Ransomware to thousands of individuals and companies requires an urgent need for creating a system capable of proactively detecting and preventing ransomware. In this research, a new approach is proposed to detect and classify ransomware based on three machine learning algorithms (Random Forest, Support Vector Machines , and Näive Bayes). The features set was extracted directly from raw byte using static analysis technique of samples to improve the detection speed. To offer the best detection accuracy, CF-NCF (Class Frequency - Non-Class Frequency) has been utilized for generate features vectors. The proposed approach can differentiate between ransomware and goodware files with a detection accuracy of up to 98.33 percent.
勒索软件是构成网络安全领域重大挑战的最严重威胁之一。网络犯罪分子利用这种攻击来加密受害者的文件或感染受害者的设备,以索要赎金来恢复对这些文件和设备的访问权限。勒索软件对成千上万的个人和公司的威胁不断升级,迫切需要创建一个能够主动检测和预防勒索软件的系统。在本研究中,提出了一种基于三种机器学习算法(随机森林、支持向量机和Näive贝叶斯)的勒索软件检测和分类新方法。采用样本静态分析技术直接从原始字节中提取特征集,提高了检测速度。为了提供最佳的检测精度,采用CF-NCF (Class Frequency - Non-Class Frequency)方法生成特征向量。该方法可以区分勒索软件和恶意软件文件,检测准确率高达98.33%。

Optimization of Energy-Efficient Cloud Radio Access Networks for 5G using Neural Networks 基于神经网络的5G高能效云无线接入网优化
Maha Fathy, Mohamed Salah Abood, Mustafa Maad Hamdi
Since proposed, Cloud Radio Access Network (Cloud-RAN) gives a committed architecture suitable for fulfilling 5G networks' applications. Cloud-RAN can solve challenges related to ever-evolving networks' mobile operators and an ever-growing number of end-users. Cloud-RAN architecture maintains both profitability and quality of service (QoS) . In this paper, power consumption is jointly formulated as power minimization beamforming and RRHs selection problem. Using the conventional convex or heuristic optimization approaches to find optimal solutions is highly complex; hence, we introduce an Artificial Neural Network (ANN) - based optimization model that aims to optimize the active Remote Radio Heads (RRHs) numbers in remote network sites and the consumed power. The proposed model considers various signal to interference plus noise ratios per client and power consumption models. Specifically, the model uses an adopted Bi-Section Group Sparse Beamforming (GSBF) optimization algorithm to reach near optimum solutions. Obtained validated results encourage machine learning techniques to reduce both the complexity and power consumption in such an emerging area.
自提出以来,云无线接入网(Cloud- ran)提供了适合实现5G网络应用的承诺架构。Cloud-RAN可以解决与不断发展的网络移动运营商和不断增长的终端用户数量相关的挑战。云- ran架构同时保持了盈利能力和服务质量(QoS)。本文将功率消耗联合表述为功率最小化波束成形和RRHs选择问题。使用传统的凸或启发式优化方法寻找最优解是非常复杂的;因此,我们引入了一种基于人工神经网络(ANN)的优化模型,旨在优化远程网络站点的有效远程无线电头(RRHs)数量和消耗的功率。该模型考虑了每个客户端不同的信噪比和功耗模型。该模型采用双截面群稀疏波束形成(GSBF)优化算法求解近似最优解。获得的验证结果鼓励机器学习技术在这样一个新兴领域降低复杂性和功耗。

A Cyber Physical System based Stochastic Process Language With NuSMV Model Checker 基于NuSMV模型检查器的随机过程语言的网络物理系统
Pouria Khanzadi, Shirin Kordnoori, Zahra Vasigh, H. Mostafaei, Ehsan Akhtarkavan
Nowadays, cyber physical systems are playing an important role in human life in which they provide features that make interactions between human and machine easier. To design and analysis such systems, the main problem is their complexity. In this paper, we propose a description language for cyber physical systems based on stochastic processes. The proposed language is called SPDL (Stochastic Description Process Language). For designing SPDL, two main parts are considered for Cyber Physical Systems (CSP): embedded systems and physical environment. Then these parts are defined as stochastic processes and CPS is defined as a tuple. Syntax and semantics of SPDL are stated based on the proposed definition. Also, the semantics are defined as by set theory. For implementation of SPDL, dependencies between words of a requirements are extracted as a tree data structure. Based on the dependencies, SPDL is used for describing the CPS. Also, a lexical analyzer and a parser based on a defined BNF grammar for SPDL is designed and implemented. Finally, SPDL of CPS is transformed to NuSMV which is a symbolic model checker. The Experimental results show that SPDL is capable of describing cyber physical systems by natural language.

Application of MQ-Sensors to Indoor Air Quality Monitoring in Lab based on IoT 基于物联网的mq传感器在实验室室内空气质量监测中的应用
Hussein J. Khadim, Faik K. Obaed, Ziad T. Abd Ali
Air pollution levels have been rising around the world in recent years. Long-term pollution exposure causes a variety of ailments, including lung disease, heart disease, and eye irritation. The term “indoor air quality” refers to the building’s residents' air quality. Physical variables, chemical or gaseous pollutants, and biological factors. Toxic gases are likely to be present in any laboratory where experiments or research are carried out. These contaminants can harm the health of the people that are working there, and the important work that is being done in this environment remains unaffected. A web-based system for indoor air quality monitoring in lab IAQML is presented in this study. The project was established to keep track of air quality metrics in the lab environment like carbon dioxide, carbon monoxide, alcohol, phenol, toluene, LPG, benzene, ammonia, and methane, if not properly maintained, this can have an impact on the inhabitants' comfort, health, and indoor working conditions. In general, the proposed method involves a selection of metal oxide MQ-sensors, and a Wi-Fi module connected to an Arduino microcontroller. The measured data from sensors is calculated in ppm units and then displayed on the Android device. Also, gas data is sent to the webpage through the ThingSpeak platform dashboard. The system has a notification function to alert students and workers in the laboratory when measurements of air quality are above or below specified thresholds. On the other hand, this allows for a well-controlled and maintained the quality standard for indoor air pollutants.
近年来,世界各地的空气污染水平一直在上升。长期暴露在污染中会导致各种疾病,包括肺病、心脏病和眼睛发炎。“室内空气质量”是指建筑物内居民的空气质量。物理变量,化学或气体污染物,以及生物因素。在进行实验或研究的任何实验室中都可能存在有毒气体。这些污染物会损害在那里工作的人的健康,而在这种环境中进行的重要工作不受影响。提出了一种基于网络的实验室室内空气质量监测系统。该项目的建立是为了跟踪实验室环境中的空气质量指标,如二氧化碳、一氧化碳、酒精、苯酚、甲苯、液化石油气、苯、氨和甲烷,如果维护不当,这可能会对居民的舒适、健康和室内工作条件产生影响。一般来说,所提出的方法包括选择金属氧化物mq传感器,以及连接到Arduino微控制器的Wi-Fi模块。传感器的测量数据以ppm为单位计算,然后显示在Android设备上。此外,气体数据通过ThingSpeak平台仪表板发送到网页。该系统具有通知功能,当空气质量测量值高于或低于指定阈值时,会向实验室的学生和工作人员发出警报。另一方面,这可以很好地控制和维持室内空气污染物的质量标准。

Arian Yousefiankalareh, Taraneh Kamyab, Farzad Shahabi, Ehsan Salajegheh, Hossein Mirzanejad, Mahsa Madadi Masouleh
In this paper, a system for face detection based on the generalized BOW method is proposed. We have utilized the space pyramid matching (SPM) method to overcome the neglected problem of space order of BOW. In the feature extraction stage, we have used SIFT method which is resistant against local variations. Sparse presentations usually are linearly separable; hence in the proposed system, we have utilized the sparse codding method in the feature learning stage. In the polling stage, we have used maximum polling operation to reach a unified vector from multiple descriptor vectors. Finally, a support vector machine classifier is used to classify face descriptor vectors. Simulation results show high accuracy of classification (ACC=0.9952) and its resistivity against previous methods.

The limitations of this method are widely known and clearly understood, it is time-consuming, prone to errors and there is always a chance of proxy attendance. Many techniques that are implemented in today’s time are vastly unreliable and are majorly inefficient, like biometrics and Radio Frequency Identification (RFID), more importantly when there is a pandemic that majorly spreads via touch. This clearly presents an opportunity in the field of facial feature detection and face recognition. We propose an effective and modish solution to mark attendance using the face recognition technique including Haar Cascade and Local Binary Pattern Histogram algorithms. The system will recognize the face of an individual or multiple students and compare them with the predefined face encoding to make a CSV file of attendees with their details. To create the database we will use image augmentation techniques. This system can also be used to tackle the problem of fake attendance and proxies.
在过去的几十年里,学生的出勤都是通过纸质的方式进行的。这种方法的局限性众所周知,也很清楚,它耗时,容易出错,而且总是有代理出席的机会。当今实施的许多技术非常不可靠,效率也很低,比如生物识别技术和无线射频识别(RFID),在主要通过触摸传播的大流行中,这一点尤为重要。这显然为人脸特征检测和人脸识别领域提供了机会。我们提出了一种有效和时尚的解决方案,使用人脸识别技术,包括哈尔级联和局部二值模式直方图算法来标记出勤。该系统将识别单个或多个学生的面部,并将其与预定义的面部编码进行比较,从而将与会者的详细信息生成CSV文件。为了创建数据库,我们将使用图像增强技术。这个系统也可以用来解决假出勤和代理的问题。

A New Wavelet Completed Local Ternary Count (WCLTC) for Image Classification 一种新的用于图像分类的小波完全局部三元计数方法

To overcome noise sensitivity and increase the discriminative quality of the Local Binary Pattern, a Completed Local Ternary Count (CLTC) was developed by combining the Local Ternary Pattern (LTP) with the Completed Local Binary Count (CLBC) (LBP). Furthermore, by integrating the proposed CLTC with the Redundant Discrete Wavelet Transform (RDWT) to construct a Wavelet Completed Local Ternary Count, the proposed CLTC’s discriminative property is improved (WCLTC). As a result, more accurate local texture feature capture inside the RDWT domain is possible. The proposed WCLTC is utilised to perform texture and medical image classification tasks. The WCLTC performance is evaluated using two benchmark texture datasets, CUReT and Outex, as well as three medical picture databases, 2D Hela, VIRUS Texture, and BR datasets. With several of these datasets, the experimental findings demonstrate a remarkable classification accuracy. In several cases, the WCLTC performance outperformed the prior descriptions. With the 2D Hela, CUReT, and Virus datasets, the WCLTC achieves the highest classification accuracy of 96.91%, 97.04 percent, and 72.89%, respectively.
为了克服噪声敏感性和提高局部二值模式的判别质量,将局部三值模式(LTP)与局部二值模式(CLBC) (LBP)相结合,提出了一种完全局部三值计数(CLTC)方法。此外,通过将所提出的CLTC与冗余离散小波变换(RDWT)相结合,构造小波完备局部三元计数,提高了所提出的CLTC的判别性(WCLTC)。因此,可以在RDWT域内更准确地捕获局部纹理特征。该方法用于纹理和医学图像的分类。使用CUReT和Outex两个基准纹理数据集以及三个医学图像数据库(2D Hela、VIRUS texture和BR数据集)对WCLTC性能进行了评估。在这些数据集中,实验结果显示了显著的分类准确性。在一些情况下,WCLTC的性能优于前面的描述。对于2D Hela、CUReT和Virus数据集,WCLTC的分类准确率最高,分别为96.91%、97.04%和72.89%。
