Recent studies have focused on leveraging large-scale artificial intelligence (LAI) models to improve semantic representation and compression capabilities. However, the substantial computational demands of LAI models pose significant challenges for real-time communication scenarios. To address this, this paper proposes utilizing knowledge distillation (KD) techniques to extract and condense knowledge from LAI models, effectively reducing model complexity and computation latency. Nevertheless, the inherent complexity of LAI models leads to prolonged inference times during distillation, while their lack of channel awareness compromises the distillation performance. These limitations make standard KD methods unsuitable for task-oriented semantic communication scenarios. To address these issues, we propose a fast distillation method featuring a pre-stored compression mechanism that eliminates the need for repetitive inference, significantly improving efficiency. Furthermore, a channel adaptive module is incorporated to dynamically adjust the transmitted semantic information based on varying channel conditions, enhancing communication reliability and adaptability. In addition, an information bottleneck-based loss function is derived to guide the fast distillation process. Simulation results verify that the proposed scheme outperform baselines in term of task accuracy, model size, computation latency, and training data requirements. © 1967-2012 IEEE.

It is argued that the data-base of a nation-wide organization will exhibit geographic locality of reference. That is, most of the transactions homing on a given component of the data base originate from a particular geographic region. At the same time there is a need to operate the collection of components as a single data base to provide for occasional transactions which cross regional boundaries, and for managerial queries and retrieval operations that span the entire data base. There are several examples of this associated with business and industry: credit and inventory records for example. Modest CPU power will suffice to perform most transaction processing on the data base. We are therefore led to consider a network of identical mini computers (or midis). Each host will execute an identical copy of the operating system in the network. The machines differ only= their complement of hardware (number of discs, primary storage size, etc.) and in the data they hold. Hence we assume that we are able to specify host hardware, host software and communications subnetwork as a single integrated system. The major goal of this work has been to investigate how far these freedoms can be exploited to yield simple elegant structures. The paper summarizes the design of the communication nucleus (4) of the network and focusses primarily on the design of the software to support transaction processing against the data base (3). Processor distribution is extended to include the ideas of a terminal host, a disc host, a central host and a communications device. The application of the proposed architecture to a typical commercial data processing problem is outlined.

Energy efficiency is a unique challenge for designing routing protocols in wireless sensor network (WSN) to extend the lifetime of the entire network because sensor nodes are power constrained devices. To solve this problem, in this paper, we propose a data fusion and tree-based clustering routing algorithm (DFTBC). DFTBC designing consists of two main works. In the first work, tree-based clustering routing technique is used to connect the nodes in a cluster to form a minimum spanning tree, where each node communicates only with its nearest neighbor using distance and remaining energy of nodes to decide which node will be the cluster head (CH). In the second work, we fuse one or more packets to generate a packet with a smaller size based on the Dempster-Shafer and Slepian-Wolf theory. Our simulation results show that the network lifetime with using of our proposed protocol can be improved about 350% and 35% compared to low-energy adaptive clustering hierarchy (LEACH) and power-efficient gathering in sensor information system (PEGASIS), respectively. © Springer International Publishing Switzerland 2015.

In this paper, we propose Greedy with Path Optimization Routing (GPOR), a novel geographic routing protocol for wireless sensor networks. GPOR finds initial routing paths by following a greedy with recovery strategy, then uses a follow-up technique to optimize the paths. An attempt is also made to create routing entries applicable to destination areas rather than individual nodes. Main advantages of GPOR are path optimization and void avoidance capacities. We implement GPOR in ns-2 and present simulation results. ©2010 IEEE.

This study aims at exploring the cybersecurity threats in line with the awareness of Saudi Arabia nationals. This paper analyzes the recent threats reports conducted by IBM, McAfee and Kaspersky. Then this paper matches the analyzed threats reports with the awareness of the Saudi nationals by examining five surveys of related studies. The results of the analysis indicate the following: Saudi Arabia is considered one of the main targets in cybersecurity with a very costly data breach. Healthcare, Financial, technology, Multiple, Individual/private, and public sectors should be given a high priority and must implement extensive trainings and awareness programs. Also, malware, account hijacking, system errors are the most widely and costly threats and awareness should be targeting these threats. Also, the study concludes that most Saudis are aware of the security tools but there are a large number that do not use nor know about these tools. The study also has found that a large number of Saudis did not receive any awareness nor training programs and businesses are not paying much attention in this regard. The study also has found that a huge number of Saudis do not know how nor want to report cybercrimes. © 2021 IEEE.

Rain attenuation characteristics of up- and down-link radio waves of Ku-band satellite communications in both Japan and Indonesia are presented for the past three years of 2003-2005, using Japan fs domestic communication satellite Superbird C (14°4 E in orbit) that connects Research Institute for Sustainable Humanosphere of Kyoto University (RISH) to Equatorial Atmosphere Radar Observatory (EAR;0.2° S, 100.3° E). The yearly cumulative time percentages of the observed rain attenuation are in good agreement with the ITU-R (International Telecommunication Union. Radiocommunication Sector) predictions for both locations in Japan and Indonesia. At EAR in Indonesia, however, the time percentages of both up- and down-link attenuation become much smaller than the ITU-R predictions in the range of larger than 10 dB. This indicates the reduction of equivalent path length down to about 2 km, as also revealed by the X-band radar observations along the same propagating path. This equivalent path length seems rather short compared with those obtained in other tropical observation sites, being attributed to unique features of the EAR site that is located in a highland basin and has a comparatively low elevation angle of 39°even in the tropics.

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. © 2022 IEEE.
