Protecting the security and privacy of data has become extremely important in this period, especially with the increase in new technologies and the adoption of government and private agencies in converting all procedures from traditional paper to electronic data. Therefore, sending and receiving data requires continuous protection from any attacks that may be exposed to it that may lead to breaking confidentiality, integrity, and availability. Cryptography is one of the consent of network security basic concepts. It mainly depends on various algorithms for protection. The aim is to convert plain text to unreadable texts to protect them from penetration of confidentiality and integrity. In this paper, we cover the importance of encryption in network security and review some methodologies for encryption in network security and its role in protection.

IEEE 802.11ah is a promising wireless standard proposed to support the emerging machine-to-machine (M2M) communications. To solve the bottleneck problem of contention-based protocol, 802.11ah limits the number of channel access from the high number of connected M2M nodes by partitioning them into multiple groups with respective restricted access window (RAW). In this paper, we model the 802.11ah as an evolutionary game to analyse the network throughput and its dynamic decision-making process. In particular, the evolution dynamic of backoff misbehaviour by selfish nodes and its impact is studied through simulation of strategy revision process of the player after comparing the projected payoff of each strategy. The obtained results show that selfish strategy can cause network performance degradation by more than 10 percent although being the Evolutionary Stable Strategy (ESS) of the game. Moreover, it is observed that the selfish player has a massive advantage over the honest player in terms of throughput by more than three times. With the help of our game model, the population evolution is simulated, and the result demonstrates the increase of selfish player proportion over each strategy revision opportunity which poses a severe concern for resource availability of the honest player.

A first-hand, low-profile, two-port planar inverted-F antenna is proposed for current 4G/5G sub-3 GHz hand-portable multiple-input and multiple-output (MIMO) applications. The design features a profile of about 5 mm and dual-coplanar feeds, which are isolated using only a modified top plate, while the shared ground plane is not perturbed as in previous designs. An open-edge slot on the top of the PIFA provides a 3λ/4 current path. The proposed antenna covers approximately a 15% impedance bandwidth fraction in the range of 2.45-2.85 GHz. The simulated results, including scattering parameters, far-field radiation patterns, and the envelope correlation coefficient, all exhibit excellent features. © 2024 IEEE.

Software pipelining is a loop optimization technique that has been widely implemented in modern optimizing compilers. In order to fully utilize the instruction level parallelism of the recent VLIW DSP processors, DSP programs have to be optimized by software pipelining. However, because of the transformation of the original sequential code, a software-pipelined loop is often difficult to understand, test, and debug. It is also very difficult to reuse and port a software-pipelined loop to other processors especially when the original sequential code is unavailable. In this paper we propose a de-pipelining technique, which converts the optimized assembly code of a software-pipelined loop back to a semantically equivalent sequential counterpart. Preliminary experiments on 20 assembly programs verifies the validity of the proposed depipelining algorithm.

This paper develops a novel approach for multi-target tracking, called box-particle intensity filter (box-iFilter). The approach is able to cope with unknown clutter, false alarms and estimates the unknown number of targets. Furthermore, it is capable of dealing with three sources of uncertainty: stochastic, set-theoretic and data association uncertainty. The box-iFilter reduces the number of particles significantly, which improves the runtime considerably. The low particle number enables this approach to be used for distributed computing. A box-particle is a random sample that occupies a small and controllable rectangular region of non-zero volume. Manipulation of boxes utilizes the methods from the field of interval analysis. Our studies suggest that the box-iFilter reaches an accuracy similar to a sequential Monte Carlo (SMC) iFilter but with much less computational costs.

Malware identification is essential for safeguarding digital systems from cyber attacks, and machine learning techniques are proving to be efficient in this field. This systematic literature re-view thoroughly analyzes research undertaken from 2020 to 2024 on malware detection using machine learning techniques, with a specific emphasis on analysis and tools. This research follows systematic literature review procedures to identify notable developments and trends in machine learning-based malware detection. The examination focuses on research approaches, highlighting the use of supervised, unsupervised, and deep learning algorithms. The research also examines the use of fundamental tools and frameworks for machine-learning-based malware detection. The assessment includes open-source software tools used for data preparation, feature extraction, and model evaluation. The research also explores the practical consequences of using machine learning for detecting malware. The evolution, classification, trends, and possible hazards linked to malicious software, specifically on Android and network platforms, have been the subject of an abundance of research. Nonetheless, a significant research void persists concerning the effectiveness of utilizing machine learning techniques to analyze and detect malware on di-verse platforms. By presenting a methodical examination of diverse malware analysis and detection approaches, this article attempts to bridge this disparity. The article discusses obstacles and constraints faced in machine learning-based malware detection, including dataset imbalances and adversarial assaults. The text explores possible solutions and future research paths to address these difficulties, emphasizing the importance of creating strong and adaptable detection systems. This study is a great resource for academics and practitioners that aim to strengthen cybersecurity measures and effectively address changing cyber threats.

Software pipelining is an effective technique to reduce cycle count by exploiting instruction level parallelism in loops. It has been implemented in most VLIW DSP compilers. However, software pipelining expands the code size due to the introduction of prelude and postlude. To address this problem, many VLIW DSP compilers include certain code size reduction features. During compilation, a user is given limited options of exercising these code reduction features. As a result, the tradeoff options between cycle count and code size are also limited. Yet today's software development often requires an optimum balance between code size and cycle count, which in turn requires a much wider tradeoff space. This paper presents a new heuristic code-size-constraint loop optimization approach to extend the tradeoff space. Preliminary experimental results indicate that the new approach can significantly widen the tradeoff space, thus providing DSP users with more flexibility to meet their various design criteria. © 2004 EUSIPCO.

The source resolvability problem (or resolvability problem for short) is one of random number generation problems in information theory. In the literature, the optimum achievable rates in the resolvability problem have been characterized in different two ways. One is based on the information spectrum quantity and the other is based on the smooth Rényi entropy. Recently, Nomura has revealed the optimum achievable rate with respect to the f-divergence, which includes the variational distance, the Kullback-Leibler (KL) divergence and so on. On the other hand, the optimum achievable rates with respect to the variational distance has been characterized by using the smooth Rényi entropy. In this paper, we try to extend this result to the case of other distances. To do so, we consider the resolvability problem with respect to the subclass of f-divergences and determine the optimum achievable rate in terms of the smooth Rényi entropy. The subclass of f-divergences considered in this paper includes typical distance measures such as the total variational distance, the KL divergence, the Hellinger distance and so on.

The sixth-generation (6G) wireless communication networks are envisioned to deliver improved Quality of Services (QoS) such as data-rate, latency, localization, etc., compared to 5G services. This demand will mainly arise due to the massive Internet of Things (IoT) connections among billions of embedded devices. It is worth noting that these IoT devices are constrained in nature in terms of memory, computation and most importantly power. Low-power wireless computing necessitates a link-layer technology that considers the aforementioned IoT device requirements such as low-power, low data-rate, long-range and energy efficient reliable communications. Long Range Radio (LoRa) technology has recently become widely popular to facilitate low-power, long-range communication, while other similar technologies struggle to achieve long-range transmissions. The LoRA standard defines several PHY and MAC sub-layer specifications for Low-Power Wide Area networks (LPWAN) that can be used to build several IoT applications. With 6G communications, an IoT application is expected to consist of hundreds of devices connected at a time, and this will need a proper scheduling mechanism among these devices for optimal performance. The LoRa standard does not define any scheduling mechanism and leaves it to the research community to explore. In this paper, we propose a distributed scheduling mechanism under the supervision of a common LoRa gateway. The proposed mechanism focuses on a Lightweight DynamicScheduling (LIDS) scheme to minimize loss in data transmissions through collisions. The proposed mechanism optimizes the power consumption to achieve the desired level of QoS requirements such as throughput and latency.

Because IEEE802.15.4-based wireless sensor networks (WSNs) and IEEE802.11-based wireless local area networks (WLANs) use same ISM frequency bands, they interferes each other. Based on the past researches, the interference makes severe impacts on the performances of WSNs rather than that of WLANs. This paper proposes a method to improve IEEE802.15.4-based WSNs performances coexisting with WLANs by transmitting only beacon frames in interference-free-channels. The method increases the reliability of beacon frames as well as overall channel utilizations. The effectiveness of the proposed method is evaluated through the extensive simulations.
