Device-to-device (D2D) communication underlaying cellular networks can improve the performance of cellular systems and it provides an effective way to meet growing mobile traffic and capacity demand. When user equipments are located in close proximity, they can communicate through direct links. In this case, D2D links can increase both energy and spectrum efficiency by reusing uplink (UL) cellular resources while satisfying the users' quality-of-service requirements. However, integrating D2D links into the cellular infrastructure causes an interference since D2D communication can increase co-channel interference and degrade cellular users' transmission link quality. In this paper, the interference mitigation techniques including power control, multiple antenna and resource allocation based on graph coloring are proposed for D2D communications underlaying cellular systems to increase the data rate of both the cellular users and D2D pairs. Compared to the prior works, in the proposed algorithm, D2D and cellular users have same priority for resource allocation. Finally, the proposed algorithm improves the overall system capacity significantly.
基于蜂窝网络的设备对设备(D2D)通信可以提高蜂窝系统的性能,为满足日益增长的移动流量和容量需求提供了有效途径。当用户设备位于近距离时,它们可以通过直接链接进行通信。在这种情况下,D2D链路可以在满足用户业务质量要求的同时,通过重用上行链路(UL)蜂窝资源,提高能量和频谱效率。然而,将D2D链路集成到蜂窝基础设施中会产生干扰,因为D2D通信会增加同信道干扰并降低蜂窝用户的传输链路质量。本文针对蜂窝系统底层的D2D通信,提出了功率控制、多天线和基于图着色的资源分配等抗干扰技术,以提高蜂窝用户和D2D对的数据速率。与之前的工作相比,在本文算法中,D2D和蜂窝用户具有相同的资源分配优先级。最后,该算法显著提高了系统的整体容量。

The fast response to a disaster is a key factor in rescuing victims who are trapped in the affected areas. The high amount of casualties as well as life and medical resource allocation cause the complexity of disaster rescuing. This paper concentrates on developing a multi-objective (MO) optimization model and adopts an algorithm named Probabilistic Solution Discovery Algorithm (PSDA) to generate a set of Pareto solutions on account of (i) the affected location, (ii) the number of victims in the affected location, (iii) the amount of resource, including food, water, and medicine, (iv) the location of the resource, (v) the deployment of UAVs. PSDA is used to solve the MO model, each of the Pareto solutions is an emergency rescuing strategy. A study case is provided to validate the perspectives. The results of resource allocation generated with the five aforementioned factors have confirmed the effectiveness of the proposed solution.
对灾难的快速反应是营救被困灾区灾民的关键因素。大量的人员伤亡以及生命和医疗资源的分配造成了灾难救援的复杂性。本文致力于开发一种多目标(MO)优化模型,并采用一种名为 "概率解发现算法"(PSDA)的算法来生成一组帕累托解,其考虑因素包括:(i) 受灾地点;(ii) 受灾地点的灾民数量;(iii) 包括食物、水和药品在内的资源数量;(iv) 资源的位置;(v) 无人机的部署。使用 PSDA 对 MO 模型进行求解,每个帕累托方案都是一种紧急救援策略。提供了一个研究案例来验证这些观点。上述五个因素产生的资源分配结果证实了所提方案的有效性。

Network slicing techniques are paramount for the operation of commercial networks, as the 5G networks community widely accepts them. These techniques allow the creation of multiple virtual networks on top of a physical network to isolate the traffic and guarantee the applications' requirements. These will allow the deployment of more tailored use cases, such as disaggregated services and specific highly consuming multimedia services. Therefore, several network slicing techniques are proposed in this paper to obtain traffic isolation in a 5G infrastructure. Specifically, edge and cloud architectures and alternatives to traditional network stack protocols are considered in the proposed solutions when slicing their virtual networks. Moreover, this paper describes which use cases are the most suitable for each proposed network slicing technique.

Onboard smartphone sensors provide ample data modalities which can be used to determine the way a phone is being used. However, in order for use case detection systems to be unobtrusive to users, the classification algorithms and the number of sensors should be kept simple and at a minimum. In this paper light, accelerometer and orientation sensor measurements are recorded for 4 different phone use cases and results from 3 different classifiers (K-means, Naive-Bayes, Neural Network) are compared to identify the sensor modality and classification algorithm that provides the highest accuracy for use case detection. The onboard accelerometer is found to be the sensor modality with highest accuracy across all the classifiers, and the neural network is identified as being the best performing classifier. A discussion of the results linking back to theoretical aspects of the classifiers is also given.

Artificial Neural Network (ANN)-Aided Signal Demodulation in a SiPM-Based VLC System 基于sipm的VLC系统中的人工神经网络辅助信号解调
Pub Date : 2022-11-30 DOI: 10.1109/ITNAC55475.2022.9998328

This paper describes a new type of data-driven signal demodulation technique using an artificial neural network (ANN) in a silicon photomultiplier (SiPM) based visible light communication (VLC) system. SiPMs can potentially be used to create the most sensitive optical receiver in VLC since it contains a large array of microcells and each microcell is capable of detecting individual photons. However, after each photon is detected, the associated microcell needs a period to recover. This means that the photon counting rate is not linearly related to the intensity of the light received by the SiPM and this effect causes a unique form of signal distortion when the transmission data rate becomes high. In this paper, an ANN aided data detection method is studied when the received signal is influenced by the SiPM nonlinearity. Both a single neuron based linear classifier and an ANN based non-linear classifier are introduced and explained in detail. The bit error rate (BER) results suggest that the ANN based receiver can significantly reduce the negative impacts caused by the SiPM nonlinearity for a wide range of irradiance levels.
本文介绍了一种基于硅光电倍增管(SiPM)的可见光通信(VLC)系统中基于人工神经网络(ANN)的数据驱动信号解调技术。sipm可以潜在地用于创建VLC中最灵敏的光学接收器,因为它包含大量的微单元阵列,每个微单元都能够检测单个光子。然而,在检测到每个光子后,相关的微单元需要一段时间来恢复。这意味着光子计数率与SiPM接收到的光的强度不是线性相关的,当传输数据速率变得很高时,这种效应会导致一种独特的信号失真形式。本文研究了接收信号受SiPM非线性影响时的人工神经网络辅助数据检测方法。介绍了基于单神经元的线性分类器和基于人工神经网络的非线性分类器。误码率(BER)结果表明,在较宽的辐照水平范围内,基于人工神经网络的接收机可以显著降低由SiPM非线性引起的负面影响。

the technologies for low powered wide area networks (LPWAN) are readily available and utilized for performance advantages in a range of industries. The challenge for research is to identify capable radio signals that propagate over the required geographic regions and physical obstacles. Also, to design and standardize protocols with sufficient load and performance capability. The Internet of Things (IoT) is motivating the search for capable network solutions as industries, such as agriculture, seek working control solutions for their supply chain and production requirements. Critical for network performances are security features that protect communications and assure the intended message. In this research we evaluated the security features of one common LPWAN protocol for performance against alternative cryptographic security mechanisms. Performance differences are found between the default algorithm and others suggesting model design trade-offs and areas for further research. The contribution of this paper is awareness of the potential scope for improvements to IoT LPWAN communications security, and the cost trade-offs between different wireless network cryptographic solutions.

A system of protocols is defined which enables suitably equipped systems or devices to record validated “facts” in a network of servers in such a way that only facts which are genuinely true can be validated by the network. The servers or devices using this network make use of remote attestation to provide this secure and integrated network, which is called, hence-forth, Certnet (Certification Network). Certnet of this paper can be envisaged, for example, as providing rigorous fact-checking for a news service. Currently any individual trying to capture media evidence (photo or video) has no way to certify their evidence. Certnet will provide this missing certification of evidence, for suitable equipment.

In addition to cache poisoning attacks, the privacy leakage has become a critical issue in DNS nowadays. Especially, the communication between the DNS full-service resolver and the authoritative DNS servers may go through multiple ISP networks. Thus, if the communication path contains areas with different privacy policies, the security and privacy in DNS domain name resolution cannot be guaranteed. To mitigate cache poisoning attacks and protect the privacy of the Internet users, we propose a novel architecture that encrypts all DNS communications with DoH. In the proposed architecture, in addition to the communication between the end clients and the DNS full-service resolvers, that between the DNS full-service resolvers and the authoritative DNS servers is also covered by DoH. As a result, not only the risk of cache poisoning attacks can be dramatically mitigated on DNS full-service resolver but also the risk of eavesdropping on DNS traffic can be reduced. Moreover, the proposed architecture is the first approach to pure DoH-based domain name resolution including DNS authoritative DNS servers.
除了缓存投毒攻击之外,隐私泄露也成为当前DNS的一个重要问题。特别是DNS全业务解析器与权威DNS服务器之间的通信可能要经过多个ISP网络。因此,如果通信路径中包含不同隐私策略的区域,则无法保证DNS域名解析的安全性和保密性。为了减轻缓存中毒攻击和保护互联网用户的隐私,我们提出了一种新的架构,该架构使用DoH加密所有DNS通信。在该架构中,除了终端客户端与DNS全服务解析器之间的通信外,DNS全服务解析器与权威DNS服务器之间的通信也被DoH覆盖。因此,在DNS全服务解析器上,不仅可以显著降低缓存投毒攻击的风险,还可以降低DNS流量被窃听的风险。此外,本文提出的架构是第一个基于doh的纯域名解析方法,包括DNS权威DNS服务器。

Adaptive Client Model Update with Reinforcement Learning in Synchronous Federated Learning 同步联邦学习中基于强化学习的自适应客户端模型更新

Federated learning is widely applied in green wireless communication, mobile technologies and daily life. It allows multiple parties to jointly train a model on their combined data without revealing any of their local data to a centralized server. However, in practical applications, federated learning requires frequent communication between clients and servers, which brings a considerable burden. In this work, we propose a Federated Learning Deep Q-Learning (FL-DQL) method to reduce the communication frequency between clients and servers in federated learning. FL-DQL selects the local-self-update times of a client adaptively and finds the best trade-off between local update and global parameter aggregation. The performance of FL-DQL is evaluated via extensive experiments with real datasets on a networked prototype system.

联邦学习在绿色无线通信、移动技术和日常生活中有着广泛的应用。它允许多方在其组合数据上联合训练模型,而无需向中央服务器透露任何本地数据。然而,在实际应用中,联邦学习需要客户端和服务器之间频繁的通信,这带来了相当大的负担。在这项工作中,我们提出了一种联邦学习深度q -学习(FL-DQL)方法来减少联邦学习中客户端和服务器之间的通信频率。FL-DQL自适应地选择客户机的本地自更新时间,并在本地更新和全局参数聚合之间找到最佳折衷。通过在网络原型系统上使用真实数据集进行大量实验,对FL-DQL的性能进行了评估。实验结果表明,FL-DQL有效地降低了节点间的通信开销,符合绿色倡议。

It allows multiple parties to jointly train a model on their combined data without revealing any of their local data to a centralized server. However, in practical applications, federated learning requires frequent communication between clients and servers, which brings a considerable burden. In this work, we propose a Federated Learning Deep Q-Learning (FL-DQL) method to reduce the communication frequency between clients and servers in federated learning. FL-DQL selects the local-self-update times of a client adaptively and finds the best trade-off between local update and global parameter aggregation. The performance of FL-DQL is evaluated via extensive experiments with real datasets on a networked prototype system. Results show that FL-DQL effectively reduces the communication overhead among the nodes in our experiments which conforms to the green initiative.","PeriodicalId":205731,"journal":{"name":"2022 32nd International Telecommunication Networks and Applications Conference (ITNAC)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125208151","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}

Poverty has posed many threats to the children's education. Children in low-income families tend to have uneducated and/or very busy parents, and their reading after school is less being instructed and supported by their parents even they want to support but without the capacity and/or sufficient time to read and understand the huge volume of stories and novels. In this paper, we aim to tackle the above challenges and develop a rapid reading comprehension system to assist those parents rapidly understanding the story content by proposing a novel system that is capable of generating and visualising story plots from the massive literature narratives. Meanwhile, the visualised story plots are represented as a sequenced knowledge graph, helping those uneducated or busy parents grasp the story's linguistic meanings and flow. Furthermore, a well-known fiction book, i.e., “Alice in Wonderland” is utilised as case studies to validate the proposed system. The primary experimental results reveal that story plot extraction can effectively provide explicit information for presenting storylines chapter by chapter at the early stage of this research initiative.
贫困给孩子们的教育带来了许多威胁。低收入家庭的孩子往往没有受过教育和/或非常忙碌的父母,他们放学后的阅读很少得到父母的指导和支持,即使他们想要支持,但没有能力和/或足够的时间阅读和理解大量的故事和小说。在本文中,我们旨在解决上述挑战,并开发一个快速阅读理解系统,通过提出一个新颖的系统,能够从大量的文学叙事中生成和可视化故事情节,帮助这些父母快速理解故事内容。同时,将可视化的故事情节以有序的知识图谱的形式呈现,帮助未受教育或忙碌的父母掌握故事的语言意义和流程。此外,我们还以著名的小说《爱丽丝梦游仙境》为例,对所提出的系统进行了验证。初步实验结果表明,在本研究的早期阶段,故事情节提取可以有效地为逐章呈现故事情节提供明确的信息。
