Over the past few years, Internet of Things (IoT) has become one of the foremost critical innovations of the 21st century. The broad set of applications for IoT gadgets includes consumer, commercial, industrial, and infrastructure spaces. It can also be used for environmental purposes, such as monitoring forest areas and preventing forest fires, which is critical for flora and animal conservation. For this purpose, the proper energy management is crucial, so that it is possible to continuously monitor the forest areas. In this paper, a method for extending the lifetime of devices that surveil such locations is presented. The created system employs technology based on the LoRaWAN protocol, which is a highly promising technology for wide access networks and sensor applications. A learning-automata-based energy efficient model is proposed to increase the device lifetime and therefore, the lifetime of the entire network. The suggested energy-efficient approach is tested using simulation results, which show that it increases device longevity.

Metaverse assisted Telesurgery in Healthcare 5.0: An interplay of Blockchain and Explainable AI 医疗5.0中的虚拟辅助远程手术:区块链和可解释人工智能的相互作用
Pronaya Bhattacharya, M. Obaidat, Darshan Savaliya, Sakshi Sanghavi, S. Tanwar, B. Sadoun
Smart healthcare has transitioned towards health-care 5.0, which allows ambient tracking of patients, emotive telemedicine, telesurgery, wellness monitoring, virtual clinics, and personalized care. Thus, the metaverse is a potential tool to leverage digital connectivity via improved healthcare experience in virtual environments. However, despite its potential benefits, patient’s sensitive information is captured, and digital avatars are created that interact with healthcare stakeholders for connected virtual care. As metaverse components are decentralized, blockchain (BC) is a potential solution to induce transparency and immutability in stored transactions on metaverse. For clinical decision support in BC-assisted metaverse enabled, Healthcare 5.0, accurate and interpretable diagnosis is critical. Thus, explainable AI (xAI) forms another critical component that provides trust in the healthcare informatics front. A dual solution of trusted informatics is possible via the interplay of BC and xAI in metaverse-enabled Healthcare 5.0. The article investigates the interplay through a proposed telesurgical scheme between patients, virtual hospitals, and doctors. Next, we discuss the potential challenges and present an experimental use-case of the benefits of our proposed architecture over traditional telesurgery systems.
智能医疗保健已经过渡到医疗保健5.0,它允许对患者进行环境跟踪、情感远程医疗、远程外科手术、健康监测、虚拟诊所和个性化护理。因此,虚拟世界是一种潜在的工具,可以通过改善虚拟环境中的医疗保健体验来利用数字连接。然而,尽管它有潜在的好处,但患者的敏感信息被捕获,并创建与医疗保健利益相关者互动的数字化身,以实现连接的虚拟护理。由于元数据组件是分散的,区块链(BC)是一种潜在的解决方案,可以在元数据上的存储事务中引入透明度和不可变性。对于bc辅助的启用了元数据的Healthcare 5.0中的临床决策支持,准确且可解释的诊断至关重要。因此,可解释的人工智能(xAI)构成了在医疗保健信息学领域提供信任的另一个关键组件。通过BC和xAI在支持元数据的Healthcare 5.0中的相互作用,可以实现可信信息的双重解决方案。本文通过提出的远程手术方案,探讨了患者、虚拟医院和医生之间的相互作用。接下来,我们讨论了潜在的挑战,并提出了一个实验用例,说明我们提出的架构相对于传统远程手术系统的好处。

S. Dwivedi, Ruhul Amin, Satyanarayana Vollala
Greener and more energy-efficient transportation options have pushed electric vehicles to the forefront of the global transportation market. Since then, academia and the transportation industry have tried to develop sustainable protocols that ensure dependable, scalable, and secure communication. With this vision, various security researchers have suggested authentication techniques to protect the messages exchanged between entities of the charging system. In its continuation, Kim et al. have proposed a charging system for electric vehicles based on the blockchain. With a close analysis of this protocol, our team has found that their scheme suffers from message substitution attacks, session key disclosure attacks, man-in-the-middle attacks, etc. This article proposes a secure and robust blockchain-based electric vehicle charging system using the ECC cryptosystem and lightweight one-way hash functions. Furthermore, the security of the proposed protocol is being analyzed, and the results confirm that the suggested protocol can withstand significant attacks.

Insight of Anomaly Detection with NWDAF in 5G 5G环境下NWDAF异常检测的洞察
Yachao Yuan, Christian Gehrmann, Jakob Sternby, Luis Barriga
Data analytics is regarded as an important function of 5G networks. The Network Data Analytics Function (NWDAF) is standardized in 3GPP to enhance 5G network performance by analyzing data from network functions and user equipment. Abnormal behavior detection, which is part of the NWDAF framework, has the potential to be a powerful tool to improve 5G network security. Despite this, only limited research has been conducted in the area so far. This paper explains abnormal behavior detection in NWDAF specified in 3GPP. Furthermore, we extensively review the related work and summarize open problems and provide possible future research directions.

SCAL-E: An Auto Scaling Agent for Optimum Big Data Load Balancing in Kubernetes Environments scale - e: Kubernetes环境中实现最佳大数据负载平衡的自动缩放代理
Efstratios Karypiadis, Anastasios Nikolakopoulos, Achilleas Marinakis, Vrettos Moulos, T. Varvarigou
During the past years, the issue of effectively balancing incoming big data streams has been under serious research. It still allows for new solutions, even if load balancing is already being addressed by multiple frameworks. This paper proposes a smart agent, named “SCAL-E“ that achieves balancing of big data loads and lives within the Kubernetes Environment. SCAL-E takes advantage of MongoDB’s scaling, replicating & sharding capabilities and decides when to increase or decrease its repository’s sub-components, based on the incoming load. This way, SCAL-E assures of proper resource allocation and gives efficiency to the jobs of big data storing & forwarding.
在过去的几年里,有效平衡传入的大数据流的问题一直在认真研究。它仍然允许新的解决方案,即使多个框架已经解决了负载平衡问题。本文提出了一个名为“scale - e”的智能代理,它可以在Kubernetes环境中实现大数据负载和生存的平衡。scale - e利用MongoDB的扩展、复制和分片功能,并根据传入的负载决定何时增加或减少其存储库的子组件。这样,scale - e保证了资源的合理分配,并提高了大数据存储和转发工作的效率。

A Deep Learning Based Sound Event Location and Detection Algorithm Using Convolutional Recurrent Neural Network 基于深度学习的卷积递归神经网络声音事件定位与检测算法
Hongxia Zhu, Jun Yan
With the application of sound event detection in more and more fields, an accurate sound event location and detection system has attracted wide attention. In this paper, we propose a sound event location and detection algorithm based on convolutional recurrent neural network (CRNN). In the offline phase, complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) algorithm is used to remove the noise of unknown distribution of the collected data set. Then, we extract filter banks (FBANK) features and cross correlation (GCC) features of each channel and fuse them. Finally, the features are input to CRNN which combined with soft attention mechanism to train the model. The CRNN is a multi-task learning framework. For sound category and sound location, it is realized by classification task and regression task respectively. Experimental results show that the algorithm is effective and can provide accurate category estimation and location estimation.
随着声事件检测在越来越多领域的应用,准确的声事件定位与检测系统引起了人们的广泛关注。本文提出了一种基于卷积递归神经网络(CRNN)的声音事件定位与检测算法。在离线阶段,采用自适应噪声完全集成经验模态分解(CEEMDAN)算法去除采集数据集未知分布的噪声。然后,提取各信道的滤波器组(FBANK)特征和互相关(GCC)特征并进行融合。最后将特征输入到CRNN中,结合软注意机制对模型进行训练。CRNN是一个多任务学习框架。对于声音类别和声音定位,分别通过分类任务和回归任务实现。实验结果表明,该算法是有效的,可以提供准确的类别估计和位置估计。

Evaluating the Optimal Number of Clusters to Identify Similar Gene Expression Patterns During Erythropoiesis 评估红细胞生成过程中识别相似基因表达模式的最佳簇数
H. Saadeh, Maha K. Saadeh, W. Almobaideen, Marwan Al-Tawil
Haematopoietic stem cells (HSC) are differentiated into red blood cells (erythrocytes) through a process called Erythropoiesis. During this process, the genes undergo global gene expression changes to reflect the present developmental stage. Unsupervised clustering aims at highlighting the co-expressed genes that share similar expression profiles. Some clustering algorithms, like the well-known and most commonly used K-means, need the number of clusters as input in order to group the data based on similarity measurements. Determining a sufficient number of clusters is not a straightforward task and might be tricky. Furthermore, the quality of the obtained clusters depends on how many clusters were used. In this study, three cluster validation metrics; Silhouette Score, Calinski Harabaz Index, and DaviesBouldin Score were used to evaluate the clusters obtained from the different clustering algorithms applied. For the data of Erythropoiesis, two clusters were identified as sufficient.
造血干细胞(HSC)通过红细胞生成的过程分化为红细胞(红细胞)。在这个过程中,基因经历了全局的基因表达变化,以反映当前的发育阶段。无监督聚类旨在突出具有相似表达谱的共表达基因。一些聚类算法,比如众所周知且最常用的K-means,需要簇的数量作为输入,以便根据相似性度量对数据进行分组。确定足够数量的集群并不是一项简单的任务,而且可能很棘手。此外,获得的聚类的质量取决于使用了多少聚类。在本研究中,三个集群验证指标;采用Silhouette Score、Calinski Harabaz Index和DaviesBouldin Score对不同聚类算法得到的聚类进行评价。对于红细胞生成的数据,两个集群被确定为足够的。

SaFaR: Solana Blockchain-based Optimal Route Selection Scheme for Cab Aggregators 基于Solana区块链的出租车聚合器最优路径选择方案
Pronaya Bhattacharya, A. Verma, M. Obaidat, S. Tanwar, B. Sadoun
In modern smart communities,decentralized ridesharing (RS) via cab aggregator (CA) services allow users to share trips at reduced expenses, and also help in mitigating congestion. The cab user (CU), and cab driver (CD) share sensitive information (credentials, account linkages, and location information) via open channels over CAs distributed server. During trips, in some cases, CDs do not follow an optimal path from source to destination, which leads to increased payments. Thus, inconsistencies occur due to a lack of transparency between CU, CDs, and CAs. Motivated from the same, we propose a scheme, SaFaR, that integrates consortium Solana blockchain (SBC) to assure transparency and transactional scalability between entities. CU and CD information is maintained in offline interplanetary file systems (IPFS) ledgers during the registration process, and the meta-information is stored in SBC. An optimal dynamic route algorithm is proposed based on retrospective priority queue in Dijkstra algorithm (RPQDA) is proposed on GPS-trace points obtained from path setup, that is modelled as a graph. The optimal route is stored on IPFS, so route alterations are not possible. Simulation analysis results have shown that an improvement of 99% storage cost is obtained due to IPFS, and an average improvement of 14.89% is obtained in travelling cost over dynamic and static-route setups.
在现代智能社区中,通过出租车聚合器(CA)服务的分散式拼车(RS)允许用户以更低的成本共享行程,也有助于缓解拥堵。驾驶室用户(CU)和驾驶室司机(CD)通过ca分布式服务器上的开放通道共享敏感信息(凭据、帐户链接和位置信息)。在旅行期间,在某些情况下,cd没有遵循从来源到目的地的最佳路径,这导致支付增加。因此,由于CU、cd和ca之间缺乏透明性,会出现不一致。出于同样的动机,我们提出了一个方案SaFaR,它集成了联盟索拉纳区块链(SBC),以确保实体之间的透明度和交易可扩展性。在注册过程中,CU和CD信息保存在离线星际文件系统(IPFS)分类账中,元信息存储在SBC中。提出了一种基于Dijkstra算法(RPQDA)中回溯优先队列的最优动态路由算法,该算法将gps跟踪点从路径设置中获得,并以图的形式建模。最优路由存储在IPFS中,因此不可能更改路由。仿真分析结果表明,IPFS可使存储成本提高99%,在动态和静态路由设置下,平均旅行成本提高14.89%。

Swift evolution of novel computing and communication technologies in beyond 5G networks (B5G) opens up the possibilities for advanced techniques to tackle various issues, which can not be solved by the existing frameworks. As the number of devices continuously increases, blockchain can provide a secure platform for communication among all the users in the network. Moreover, along with the security, blockchain requires low computation and also provides fast network response. Furthermore, artificial intelligence enhances the ability of devices to learn and construct knowledge about dynamic wireless environments. Recently, many researchers have shown interest in integration of both the platforms to solve the complex problems of B5G networks. This work reviews the application of both the technologies in various networks related problems recently completed by the authors. Moreover, it also discusses various possible research issues that can be handled by the integration of both platforms.
