Choosing of Telecommunications Equipment Suppliers Based on the Choquet Integral and Fuzzy Measure Variance Minimization

Telecommunications equipment suppliers play an important role in the functioning of corporations with large-scale distributed computer networks such as system integrators, Internet service providers and others. An important condition of sustainable development for these companies is effective and reasonable decision making concerning the choice of suppliers. At the same time, the amount of information to be considered in many industries for making decisions has grown several times. In accordance with the above, decision making support systems for the reliable choice of suppliers started to be developed. At the same time, the approaches to designing such systems possess some disadvantages. In order to overcome these disadvantages this article suggests an approach to decision making support for choosing telecommunication equipment suppliers based on the Choquet Integral and minimization of fuzzy measure variance. It deals with the task of criteria normalization, fuzzy measure identification, gives examples of expert estimations for criteria and also the results of supplier assessments based on which the decision is made.

FedNIDS: A Federated Learning Framework for Packet-based Network Intrusion Detection System

Network intrusion detection systems (NIDS) play a critical role in discerning between benign and malicious network traffic. Deep neural networks (DNNs), anchored on large and diverse datasets, exhibit promise in enhancing the detection accuracy of NIDS by capturing intricate network traffic patterns. However, safeguarding distributed computer networks against emerging cyber threats is increasingly challenging. Despite the abundance of diverse network data, decentralization persists due to data privacy and security concerns. This confers an asymmetric advantage to adversaries, as distributed networks face the formidable task of securely and efficiently sharing non-independently and identically distributed data to counter cyber-attacks. To address this, we propose the Federated NIDS ( FedNIDS ), a novel two-stage framework that combines the power of federated learning and DNNs. It aims to enhance the detection accuracy of known attacks, robustness and resilience to novel attack patterns, and privacy preservation, using packet-level granular data. In the first stage, a global DNN model is collaboratively trained on distributed data, and the second stage adapts it to novel attack patterns. Our experiments on real-world intrusion datasets demonstrate the effectiveness of FedNIDS by achieving an average F1 score of 0.97 across distributed networks and quickly disseminating novel attack information within four rounds of communication.

Improved and Provably Secure ECC-Based Two-Factor Remote Authentication Scheme with Session Key Agreement

The remote authentication scheme is a cryptographic protocol incorporated by user–server applications to prevent unauthorized access and security attacks. Recently, a two-factor authentication scheme using hard problems in elliptic curve cryptography (ECC)—the elliptic curve discrete logarithm problem (ECDLP), elliptic curve computational Diffie–Hellman problem (ECCDHP), and elliptic curve factorization problem (ECFP)—was developed, but was unable to address several infeasibility issues while incurring high communication costs. Moreover, previous schemes were shown to be vulnerable to privileged insider attacks. Therefore, this research proposes an improved ECC-based authentication scheme with a session key agreement to rectify the infeasible computations and provide a mechanism for the password change/update phase. The formal security analysis proves that the scheme is provably secure under the random oracle model (ROM) and achieves mutual authentication using BAN logic. Based on the performance analysis, the proposed scheme resists the privileged insider attack and attains all of the security goals while keeping the computational costs lower than other schemes based on the three hard problems. Therefore, the findings suggest the potential applicability of the three hard problems in designing identification and authentication schemes in distributed computer networks.

Optimal Control of Distributed Computing Networks With Mixed-Cast Traffic Flows

Distributed computing networks, tasked with both packet transmission and processing, require the joint optimization of communication and computation resources. We develop a dynamic control policy that determines both routes and processing locations for packets upon their arrival at a distributed computing network. The proposed policy, referred to as Universal Computing Network Control (UCNC), guarantees that packets i) are processed by a specified chain of service functions, ii) follow cycle-free routes between consecutive functions, and iii) are delivered to their corresponding set of destinations via proper packet duplications. UCNC is shown to be throughput-optimal for any mix of unicast and multicast traffic, and is the first throughput-optimal policy for non-unicast traffic in distributed computing networks with both communication and computation constraints. Moreover, simulation results suggest that UCNC yields substantially lower average packet delay compared with existing control policies for unicast traffic.

WITHDRAWN: IMPROVED RESOURCE MANAGEMENT AND UTILIZATION BASED ON A FOG-CLOUD COMPUTING SYSTEM WITH IOT INCORPORATED WITH CLASSIFIER SYSTEMS

With the rapid rise of computing devices-linked networks, the Internet of Things (IoT) has increased proportionally and speedily. After that, the size of the data generated and significantly increased computational effort. A solution for a very large workload is cloud computing significantly slowed and continues to be a problem in a distributed computer network. Addressing the workload at the network edge can enchase time feedback, and delaying the data load management task imposes performance constraints from the power source to the edge of the network, which does not support only limited battery power. Therefore, the workload must be distributed equally to the clouds and across the network.

There are considered issues of building a Low-Earth-Orbit Satellite System designed to provide the Internet of Things services and adapted to the features of the services and systems of the Internet of Things. The considered system provides the creation of the necessary telecommunication infrastructure based on the Low-Earth-Orbit Broadband Access Satellite System and places Computational Facilities into the Low-Earth-Orbit for to ensure the processing of Internet of Things devices and systems information, and perform computations. The architecture of a “Distributed Satellite” was chosen to construct the telecommunications part of the Internets of Things Satellite System. The chosen architecture allows, on the one hand, to ensure the full functionality of complex telecommunication systems, and on the other hand, to use spacecraft of the form factor nano-satellite / cub-sat. The using of the cube-sat spacecraft for development of the satellite-based system allows to significantly reduce the cost of development of the system and the time of the system deploying. A promising direction in the development of the Internet of Things systems is the implementation of the concept of “Fog Computing” for processing Internet of Things information.

It was shown the direction of transmission of the operational part of a Localized Distributed Database. Proposals are made on the distribution of the excess computational load arising in certain regions of the satellite telecommunications system's service area, involving the resource of neighboring satellite computers in its orbital plane and neighboring orbital planes. An algorithm is proposed for moving the excess computational load to the polar and oceanic regions.

Autonomous monitoring in healthcare environment: Reward-based energy charging mechanism for IoMT wireless sensing nodes

Abstract The Internet of Medical Things (IoMT) is an essential paradigm for ubiquitous monitoring in healthcare environments. The IoMT system collects data (e.g. temperature, hazardous contamination, light intensity, room and patient status, etc.) from connected medical devices and sensor nodes to a central or distributed computer network. In order for these devices and sensor nodes to continue operating, they must be charged with sufficient energy at all times. In this paper, we propose an IoMT system that employs autonomous mobile chargers, which is equipped with wireless energy transfer technology, to support sensor nodes recharging requests. In this model, the mobile charger must distribute the energy among the sensor nodes so that their operation is not interrupted. This is challenging because the mobile charger carries limited amount of energy that may not be sufficient to satisfy all recharging requests. In this paper, we propose a reward-based energy charging decision mechanism that allows mobile chargers and sensor nodes to coordinate the charging process. The proposed reward-based mechanism utilizes the Analytical Hierarchy Process (AHP) for fair distribution of energy among the nodes. This paper presents the theoretical analysis of the model and the simulation experiments. Our results show that the proposed model can support a larger number of active nodes with less energy compared to conventional first come first served methods. Also the coverage utility of sensor nodes is much higher using our method compared to the on-demand recharging request schemes found in existing studies.

A Novel Authentication Mechanism to Prevent Unauthorized Service Access for Mobile Device in Distributed Network

The growth of distributed computer networks (DCN) is simple for the user to share information and computing capabilities with the host. User identification is an essential access control mechanism for the client-server networking architecture. The perception of single sign-on allows a legitimate user to access a different service provider on a DCN using a single session key. Recently, several user identification techniques being proposed for DCN. Unfortunately, the existing proposals cannot maintain user anonymity when the majority of probable attacks. In addition, the further time synchronization mechanism they use can result in widespread overhead costs. To overcome these shortcomings, we propose a novel authentication mechanism to prevent unauthorized service access for a mobile device in distributed networks. The mechanism implements methods to generate securely encrypted keys using RSA algorithm to validate the authentication of user login id and password. Later, it implements a secure session key generation using DH algorithm which allows accessing the different services without repeating the authentication mechanism. An experimental evaluation was performed to measure execution time overhead for the registration process, an authentication process, session key generation process and Service Request Performance. The comparison results with existing authentication mechanism show an improvisation in all the measures.

Internet of instruments: Connectivity of research instruments and artificial intelligence could drastically advance experimental science.

EMBO Reports (2018) 19: e47267[OpenUrl][1][FREE Full Text][2] Biologists were among the first who embraced computers and the Internet. In the early 1990s, they used these technologies not only for communication but also for online databases to store, search, and analyze gene and protein sequence data, for protein design, or for protein folding simulation on supercomputers and distributed computer networks. It eventually spawned the field of bioinformatics, which has made an enormous impact on research in the life sciences. Curiously though, biologists have been rather slow to adopt data connectivity in the laboratory itself: while computers are ubiquitous, many instruments and tools from PCR machines to gel imaging or microscopes are still operated manually. Now, the Internet of Things (IoT) is entering biomedical research facilities, hooking up equipment for remote monitoring and data collection, which both saves costs and creates more consistent conditions for experiments. It thus paves the way for artificial intelligence (AI) and machine learning (ML) for further analysis of experimental data and images. Some scientists speculate that once AI and ML become incorporated into research, the potential of IoT could go much further than cutting costs and streamlining laboratory workflows to fundamentally change the way research is done in the life sciences. While this remains to be seen, there is already huge potential for operating laboratories more effectively and maintaining greater control over experiments, which will itself lead to improved outcomes. Indeed, greater reproducibility has been cited as one crucial benefit of being able to guarantee more consistent conditions within research equipment and the laboratory environment. An obvious advantage of IoT is the ability to monitor, for example, refrigeration units to ensure the safety of precious, sometimes irreplaceable samples, which prompted Harvard University to invest in monitoring systems to minimize risk of the freezers failing.
