However, load balancing in edge computation offloading is still a challenging problem. Meanwhile, with the continuous pursuit of low execution latency in 5G multi-scenario, the functional requirements of edge computation offloading are further exacerbated. Given the above challenges, we raise a unique edge computation offloading method in 5G multi-scenario, and consider user satisfaction. The method consists of three functional parts: offloading strategy generation, offloading strategy update, and offloading strategy optimization. First, the offloading strategy is generated by means of a deep neural network (DNN), then update the offloading strategy by updating the DNN parameters. Finally, we optimize the offloading strategy based on changes in user satisfaction. In summary, compared to existing optimization methods, our proposal can achieve performance close to the optimum. Massive simulation results indicate the latency of the execution of our method on the CPU is under 0.1 seconds while improving the average computation rate by about 10%.","PeriodicalId":100766,"journal":{"name":"Journal of Communications and Information Networks","volume":"8 3","pages":"271-282"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49953048","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}

On the one hand, RIS technology mitigates dead zones in communication systems. Additionally, it increases the data rate and communication range, enhances the communication channel by making it intelligent, and improves the system's capacity. Finally, the RIS technology improves the spectrum and energy efficiencies of the considered systems. On the other hand, transmitting diversity mitigates deep fade and helps to achieve beamforming to regulate the beam sent in a specific direction. Finally, multiple light sources help to send different versions of the same information at other time slots. Furthermore, compared to flat reflectors, concave mirrors provide economic advantages enabled by their natural shape, which helps converge the impinging light beams into the same focal point. In this paper, we harness the full potential of ORIS and MISO technologies in an FSO system by exploiting the hollow of concave reflectors to focus the reflected beams on a single user. We derive an approximated closed-form expression, provide results of the proposed ORIS-aided FSO systems' ergodic channel capacity, and discuss the suitable type of concave reflector. These results show that all types of concave mirrors provide similar results except when the thickness of the reflector is large enough to impact the reflected light.","PeriodicalId":100766,"journal":{"name":"Journal of Communications and Information Networks","volume":"8 3","pages":"295-302"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49953050","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}

As a practical instance of HMIMO, reconfigurable refractive surfaces (RRSs) equipped with numerous metamaterial elements are utilized as antennas by refracting incident signals from signal sources. In this paper, we investigate a multi-user communication system with an RRS deployed as the base station (BS)'s transmit antenna. To mitigate the high overhead of accurate channel state information (CSI) acquisition, the codebook design and beam training are employed to perform beamforming. Given the large scale of RRS, users are likely to be randomly distributed in both the near and far fields around the BS, which is unknown in advance. By considering radiation characteristics in both fields, a near-far field codebook is designed to be applicable to all users, regardless of their locations. To reduce overhead, a multi-user beam training is proposed to serve all users simultaneously by enhancing each codeword capable of covering multiple areas. Considering a general case that includes users in both fields, simulation results indicate that, without prior knowledge of user distribution, the proposed scheme outperforms state-of-the-art ones in terms of sum rate and overhead.","PeriodicalId":100766,"journal":{"name":"Journal of Communications and Information Networks","volume":"8 2","pages":"99-110"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49946750","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}

In this case, the size of the response is many times greater than the size of the request, in which the source of the request is substituted for the address of the victim. This paper presents an original method for countering DNS amplification DDoS attacks. The novelty of our approach lies in the analysis of outgoing traffic from the victim's server. DNS servers used for amplification attacks are easily detected in Internet control message protocol (ICMP) packet headers (type 3, code 3) in outgoing traffic. ICMP packets of this type are generated when accessing closed user datagram protocol (UDP) ports of the victim, which are randomly assigned by the Saddam attack tool. To prevent such attacks, we used a Linux utility and a software-defined network (SDN) module that we previously developed to protect against port scanning. The Linux utility showed the highest efficiency of 99.8%, i.e., only two attack packets out of a thousand reached the victim server.","PeriodicalId":100766,"journal":{"name":"Journal of Communications and Information Networks","volume":"8 2","pages":"111-121"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49985096","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}

Therefore, it is necessary to design an appropriate RIS reflection vector to solve the eavesdropping problem. This problem is formulated as an optimization problem whose goal is to maximize the secure energy efficiency which is defined as the ratio of the secure rate to the total energy consumption of the system via jointly optimizing the RIS reflection reflector as well as the number of RIS elements, which results in a non-convex optimization problem that is intractable to solve by traditional methods. To tackle this issue, a new algorithm by leveraging the advance of the established deep learning (DL) technique is proposed so as to find the optimal RIS reflection vector and determine the optimal number of RIS reflection elements. Simulation results show that the proposed method reaches 96% of the optimal secure energy efficiency of the genie-aided algorithm.","PeriodicalId":100766,"journal":{"name":"Journal of Communications and Information Networks","volume":"8 2","pages":"122-132"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49946746","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}

The APs can prefetch and store the files requested by users, to serve users directly in the access links. Thus low-latency transmissions are enabled as the transmission in the backhaul links is saved. However, due to the limited cache capacity, not all requested files can be stored in the APs, some of the non-cached APs then should be utilized as long as their transmission delays in the access and backhaul links can be well addressed. Two delay optimal beamformer design (DOBD) problems are formulated to minimize the overall delay incurred in the backhaul and access link transmissions via a joint optimization of the beamformer at the BS and APs. We consider the DOBD problem under non-fragment and fragment caching policies, both involving nonconvex link rate constraints. The semi-definite relaxation (SDR) and sequential convex approximation (SCA) schemes are adopted to approximate the nonconvex problems into convex ones, which are then iteratively solved. Numerical results demonstrate the convergence and improved transmission delay performance of the proposed scheme under various network settings.","PeriodicalId":100766,"journal":{"name":"Journal of Communications and Information Networks","volume":"8 2","pages":"141-154"},"PeriodicalIF":0.0,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49946747","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}

The role of machine learning (ML) and artificial intelligence (AI) driven innovations within the RAN domain is strengthening and attracting lots of attention to tackle many of the challenging problems. In this paper we surveyed RAN network base stations (BSs) clustering and its applications in the literature. The paper also demonstrates how to leverage community detection algorithms to understand underlying community structures within RAN. Tracking areas (TAs) novel framework was developed by adapting existing community detection algorithm to solve the problem of statically partitioning a set of BSs into TA according to mobility patterns. Finally, live network dataset in dense urban part of Cairo is used to assess how the developed framework is used to partition this part of the network more efficiently compared to other clustering techniques.

However, it is challenging to obtain the perfect channel state information (CSI) at the base station (BS) due to the lack of radio frequency (RF) chains at the IRS, which becomes even harder when eavesdroppers (Eves) exist. In this paper, we study the power issues in the IRS-aided SWIPT system under the imperfect CSI of BS-IRS-Eves links. We aim to minimize the transmitting power at the BS by jointly designing transmit beamforming and reflective beamforming with subject to the rate outage probability constraints of the Eves, the energy harvesting constraints of the energy receivers (ERs), and the minimum rate constraints of the information receivers (IRs). We use Bernstein-type inequality to solve the rate outage probability constraints. Afterward, the formulated non-convex problem can be efficiently tackled by employing alternating optimization (AO) combined with semidefinite relaxation (SDR) and penalty convex-concave procedure (CCP).
