The widespread application of Machine Learning techniques in patient care is currently hampered by limited dataset availability for algorithm training and validation due to the lack of standardised electronic medical records and strict legal and ethical requirements to protect patient privacy. To avoid compromising patient privacy while supporting scientific analysis on massive datasets to improve patient care, it is necessary to analyse and implement Machine Learning solutions that fulfil data security and consumption demands. In this survey paper, we meticulously explain the existing works of federated learning from many perspectives to give a thorough overview and promote future research in this area. Then, we determine the current challenges, attack vectors and potential prospects for federated learning research. We analysed the similarities, differences and advantages between federated learning and other machine learning techniques. We also discussed about system and statistical heterogeneity and related efficient algorithms.","PeriodicalId":45621,"journal":{"name":"Journal of Computer Networks and Communications","volume":"20 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77199392","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}

Many researchers have attempted to quantify the impacts of such CV applications and vehicle-to-everything (V2X) communication, or the instant and accurate communication among vehicles, devices, pedestrians, infrastructure, network, cloud, and grid. Cellular V2X (C-V2X) has gained interest as an efficient method for this data sharing. In releases 14 and 15, C-V2X uses 4G LTE technology, and in release 16, it uses the latest 5G new radio (NR) technology. Among its benefits, C-V2X can function even with no network infrastructure coverage; in addition, C-V2X surpasses older technologies in terms of communication range, latency, and data rates. Highly efficient information interchange in a CV environment can provide timely data to enhance the transportation system's capacity, and it can support applications that improve vehicle safety and minimize negative impacts on the environment. Achieving the full benefits of CVs requires rigorous investigation into the effectiveness, strengths, and weaknesses of different CV applications. It also calls for deeper understanding of the communication protocols, results with different CV market penetration rates (MPRs), CV- and human-driven vehicle interactions, integration of multiple applications, and errors and latencies associated with data communication. This paper includes a review of existing literature on the safety, mobility, and environmental impacts of CV applications; gaps in current CV research; and recommended directions for future research. The results of this paper will help shape future research for CV applications to realize their full potential.","PeriodicalId":45621,"journal":{"name":"Journal of Computer Networks and Communications","volume":"265 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80098116","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 problem is formulated as an NP-hard single non-zero programming (SNZP) optimization problem with three different throughput-based objective functions, including the maximal aggregate (MA) throughput, the max-min fair (MMF) throughput and the proportionally fair (PF) throughput. To solve the NP-hard SNZP problem, based on the optimal branch-and-bound (BnB) searching approach, two novel efficient algorithms, the optimal BnB and the suboptimal depth-first BnB (DF-BnB) algorithms, are proposed, which can be used as convenient performance benchmarks in the study of the problem considered. The complexity of the proposed algorithms is analyzed theoretically. Numerical results are presented to investigate and compare the performance and complexity of the proposed algorithms under the three different design criteria, which can help in choosing an appropriate cost function objective in practical system design.","PeriodicalId":45621,"journal":{"name":"Journal of Computer Networks and Communications","volume":"12 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2023-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74827696","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}

It focuses on the scenario where Inter-Satellite-Links (ISL) are used for massive LEO satellite constellation. Such LEO satellite network is the key to the Non-terrestrial Network (NTN) integration with 5G and beyond. The paper describes two categories of solutions. One is based on IPv6 and another is based on a new protocol, New IP. The two categories of solutions are a) using new types of addresses for LEO satellites and b) new concepts for routing with these addresses. The semantic addressing scheme leverages the characteristics of satellites with known orbit elements; and simplifies the satellite identification by using limited indexes. The routing method combines semantic addressing with source routing and generates a new semantic routing scheme. Compared with traditional methods, the new proposals dramatically reduce the workload in satellite, such as table size, Ternary Content-addressable memory (TCAM) lookups, and packet header size. Thus it is more suitable to networks in space where the harsh environment limits the hardware performance, power consumption, link bandwidth and system complexity.","PeriodicalId":45621,"journal":{"name":"Journal of Computer Networks and Communications","volume":"30 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78685871","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}

Massive Multiple-Input-MultipleOutput (MIMO) is the major key technique for the future Fifth Generation (5G) of mobile wireless communication network due to its characteristics, elements and advantages. Massive MIMO will be comprised of five major elements; antennas, electronic components, network architectures, protocols and signal processing. We realize that precoding technique is a processing technique that utilizes Channel State Information Technique (CSIT) by operating on the signals before transmitting them. This technique varies base on the type of CSIT and performance criterion. Precoding technique is the last digital processing block at the transmitting side. In this paper, linear and non-linear Precoding technique was reviewed and we proposed two techniques under each that is Minimum Mean Square Error (MMSE), Block Diagonalization (BD), Tomlinson-Harashima (TH) and Dirty paper coding (DPC). Four Precoding techniques: MMSE, BD, DPC and TH were used in the studies to power consumption, energy efficiency and area throughput for single-cell and multi-cell scenarios.
