Scaling Limits for Stochastic Network Models Application to Wireless Communications 随机网络模型在无线通信中的应用
H. Baili
The capacity of a wireless communication system is constrained by a set of scarce resources. These transmission resources must be allocated so as to maximize the capacity at the physical layer. Here stochastic control and optimization offer a powerful mathematical framework to address the issue of resource sharing; they allow to account for random behavior and dynamics at higher network layers. This work is a continuation of the research on the problem of joint power allocation and time slot scheduling in a wireless communication system. The system has time varying traffic and is handled by a single base station transmitting over time varying channels. The mobile users share each time slot and the power available at this time slot, and the performance of the allocation algorithm can be characterized by the average delay experienced by the data transmitted in the network. The proposal of an antecedent article was a heavy traffic analysis for the physical system on hand, i.e., appropriate re-scaling which lead to a diffusion approximation of the system in the sense of weak convergence. In the present article a closed form solution to the resource sharing problem is provided; the solution relies on the ergodicity of the approximate diffusion.
无线通信系统的容量受到一组稀缺资源的限制。必须对这些传输资源进行分配,以使物理层的容量最大化。在这里,随机控制和优化为解决资源共享问题提供了一个强大的数学框架;它们允许在更高的网络层解释随机行为和动态。本文是对无线通信系统中联合功率分配和时隙调度问题研究的延续。该系统具有时变业务,并由在时变信道上传输的单个基站处理。移动用户共享每个时隙和该时隙的可用功率,分配算法的性能可以通过网络中传输数据所经历的平均延迟来表征。前一篇文章的建议是对现有物理系统进行重流量分析,即适当的重新缩放,从而导致系统在弱收敛意义上的扩散近似。本文给出了资源共享问题的一种封闭形式的解决方案;解依赖于近似扩散的遍历性。

Mobility Episode Discovery in the Mobile Networks Based on Enhanced Switching Kalman Filter 基于增强交换卡尔曼滤波的移动网络移动事件发现
Toivo Vajakas, Tanel Kiis, Amnir Hadachi, E. Vainikko
The usage of mobile phones has become an important activity in our lives. The passive mobile positioning of mobiles provides large-scale data about human mobility. Hence, in this paper, we are presenting a technique based on continuous time switching Kalman filter to efficiently detect stop and move episodes. The technique has practical and theoretical advantages as the model is more closely related to measure human mobility characteristics and less sensitive to variations in radio network operations. The technique was tested on real radio network data and the results indicated significant improvement with respect to the model performance and the literature.

Performance Analysis of the Offloading Scheme in a Fog Computing System 雾计算系统卸载方案的性能分析
E. Sopin, A. Daraseliya, L. Correia
Fog computing is a good solution for response time-critical applications, which need a lot of processing time. Fog allows mobile devices to offload some tasks and, consequently, to increase battery life-time. By the way, unlike classical cloud solutions, fog computing provides very low latency thanks to its distributed computing infrastructure. In the paper, we assume that tasks are not uniform and they significantly differ in amount of required work. We propose the offloading criterion based on amount of required work for a task, so that “heavy” tasks are offloaded to the fog and “light” tasks are processed locally on mobile devices. The proposed offloading scheme is analyzed in terms of queuing systems, formulas for the main performance measures are obtained.
对于需要大量处理时间的响应时间关键型应用程序,雾计算是一个很好的解决方案。Fog允许移动设备卸载一些任务,从而延长电池寿命。顺便说一下,与传统的云解决方案不同,雾计算提供了非常低的延迟,这要归功于它的分布式计算基础设施。在本文中,我们假设任务不是统一的,它们在所需的工作量上有很大的不同。我们提出了基于任务所需工作量的卸载标准,以便“重”任务卸载到雾中,“轻”任务在移动设备上本地处理。从排队系统的角度对所提出的卸载方案进行了分析,得到了主要性能指标的计算公式。

IP Traffic Generator Using Container Virtualization Technology 基于容器虚拟化技术的IP流量生成器
R. Fujdiak, V. Uher, P. Mlynek, Petr Blazek, J. Slacik, Vladimir Sedlacek, J. Misurec, Marina Volkova, P. Chmelar
This paper describes a network traffic generator which is based on a container virtualization technology, namely Docker. The aim of the generator is the simulation of TCP/IP layer 7 (L7) traffic and attacks. The main advantages of the proposed solution are its flexibility and extensibility. The integration of a new service is as demanding as installing a service on a classical server. It is also possible to run the generator in a cloud using Docker Swarm mode. Three different web servers and one classic HTTP attack - slowloris are used for demonstration purposes. The output of the generator is a captured traffic in the pcap file format.

N. Apanasenko, E. Bakin, G. Evseev
This research is devoted to an analysis of a data transmission systems with Frequency Hopping-Spread Spectrum working in a presence of a mixture Cauchy-Gaussian noise. We consider coherent and non-coherent reception of such signals and four decision-making algorithms: correlation receiver, correlation receiver with a preliminary threshold, algorithm based on a binary quantization and algorithm based on a median statistic. As a result of the comparative analysis we figure out areas of applicability for the considered receivers and their dependency on distortion parameters.

A New Ranking Method of Alternatives for Group Decision Making in Social Networks 一种新的社会网络群体决策方案排序方法
Nadezhda Chukhno, K. Samouylov, Olga Chukhno, Anna Gaidamaka, E. Herrera-Viedma
Group decision-making (GDM) is a process that consists of choosing the best alternative or a set of alternatives from all possible, taking into account the opinions of the group of people. This technology is well researched and applied not for the first decade, however, traditional algorithms did not intend to work with a large amount of data. It means, that during assessment of alternatives each expert chooses a limited set of data that interested him. In addition, each of experts may have his own rating scale. The problem becomes critical when the number of alternatives and experts evaluating them is large, as it is happening in social network contexts. The article offers a review and a formal description of a new GDM approach in social networks. With the use of set-theoretical operations, method of alternatives ranking in the group assessment of social networks is formalized. A theorem on the conversion from the rating scale of linguistic term set (LTS) into basic LTS (BLTS) rating scale is proved. Using the UML language, a formal model was developed and a key algorithm for conversion of numerical ranks from the LTS scale into the BLTS scale was proposed. A method for extrapolating the values of ranks when the network is scaled is developed, for example, when the number of experts is modified. A case for numerical demonstration of the algorithm is presented.
群体决策(GDM)是一个过程,包括从所有可能的方案中选择最佳方案或一组方案,同时考虑到群体的意见。该技术的研究和应用并不在最初的十年,但是传统的算法并不打算处理大量的数据。这意味着,在评估备选方案时,每个专家选择一组他感兴趣的有限数据。此外,每个专家可能都有自己的评分标准。当备选方案的数量和评估它们的专家数量很大时,这个问题就变得至关重要了,就像在社交网络环境中发生的那样。本文对社交网络中的一种新的GDM方法进行了回顾和正式描述。利用集合理论运算,形式化了社会网络群体评价中的备选排序方法。证明了语言项集评定尺度向基本评定尺度转换的一个定理。利用UML语言建立了一个形式化模型,并提出了从LTS量表到BLTS量表的数值等级转换的关键算法。当网络被缩放时,例如,当专家的数量被修改时,开发了一种外推等级值的方法。最后给出了该算法的一个算例。

Performance Measures Analysis of Admission Control Scheme Model for Wireless Network, Described by a Queuing System Operating in Random Environment 随机环境下排队系统描述的无线网络准入控制方案模型的性能度量分析
Yves Adou, E. Markova, I. Gudkova
According to the latest data from the leading participants in the telecommunications market, such as Cisco Systems, the volume of traffic generated in modern wireless networks is increasing exponentially. The rapid growth of traffic, which appears in the context of providing a wide range of high-quality multimedia services to mobile network users leads to a lack of available radio spectrum. This is becoming a major problem in the development of modern wireless technologies. Mobile network operators offer various methods for solving this problem, such as the frameworks LAA and LSA, which allow more efficient use of available resources in the frequency band. In addition, as part of the implementation of various technologies to provide users services with the required level of QoS, mechanisms for managing radio resources, such as reducing the downlink power and interrupting users services can be applied. Models implementing such mechanisms can be described in the form of a queuing system with unreliable servers. This paper analyzes the performance metrics of a possible scheme for accessing the radio resources of a wireless network implemented through a mechanism for reducing the downlink power and interrupting user service. The mechanism itself is described in the form of a queuing system with unreliable servers, that are affected by a random environment.
根据思科系统(Cisco Systems)等电信市场主要参与者的最新数据,现代无线网络产生的流量正呈指数级增长。在向移动网络用户提供广泛的高质量多媒体业务的背景下,通信量的快速增长导致了可用无线电频谱的缺乏。这正在成为现代无线技术发展中的一个主要问题。移动网络运营商提供了各种方法来解决这个问题,例如LAA和LSA框架,它们可以更有效地利用频段内的可用资源。此外,作为向用户提供所需QoS水平的各种技术的实施的一部分,可以应用诸如降低下行链路功率和中断用户服务等管理无线电资源的机制。实现这种机制的模型可以用具有不可靠服务器的排队系统的形式来描述。本文分析了一种通过降低下行链路功率和中断用户服务的机制实现的访问无线网络无线电资源的可能方案的性能指标。该机制本身被描述为具有不可靠服务器的排队系统,受随机环境的影响。

Mathematical Decision Support Model for the Decommissioning of Nuclear Power Facilities 核电设施退役的数学决策支持模型
V. V. Bochkarev, A. Kryanev, D. S. Smirnov
The paper proposes a structure of a mathematical model for supporting decision-making on the decommissioning of nuclear power facilities. The proposed structure includes a scheme of analysing the various options for decommissioning nuclear power facilities based on a multi-criteria approach. In particular, along with the usual nuclear decommissioning variants (the green-field site restoration and the disposal of radioactive waste on site), the suggested model allows their optimal combination. The model takes into account the uncertainties in the initial data, including data determined expertly, whose uncertainty is described by fuzzy sets. The mathematical decision support model evaluates a large number of indicators of the nuclear facility to be decommissioned, reducing them to several aggregated criteria. Of those the most significant are the composite indicator of potential hazard and the aggregate financial indicator, taking into account the levels of their uncertainty. The proposed scheme allows finding of the optimal variant for decommissioning a nuclear facility that corresponds to the optimal correlation of criteria characterizing the maintenance of values of nuclear and radiation safety indicators and economic indicators of the decommissioned object of nuclear energy use.
提出了一种支持核电设施退役决策的数学模型结构。拟议的结构包括一项基于多标准方法分析核动力设施退役的各种选择方案的计划。特别是,与通常的核退役变体(绿地场地恢复和现场放射性废物处理)一起,建议的模型允许它们的最佳组合。该模型考虑了初始数据的不确定性,包括专家确定的数据,其不确定性用模糊集来描述。该数学决策支持模型对退役核设施的大量指标进行评估,将其简化为若干汇总标准。其中最重要的是潜在危险的综合指标和综合财务指标,同时考虑到它们的不确定性程度。拟议的方案允许找到核设施退役的最佳变量,该变量对应于表征核和辐射安全指标与退役核能使用对象的经济指标维持值的标准的最佳相关性。

The proposed structure includes a scheme of analysing the various options for decommissioning nuclear power facilities based on a multi-criteria approach. In particular, along with the usual nuclear decommissioning variants (the green-field site restoration and the disposal of radioactive waste on site), the suggested model allows their optimal combination. The model takes into account the uncertainties in the initial data, including data determined expertly, whose uncertainty is described by fuzzy sets. The mathematical decision support model evaluates a large number of indicators of the nuclear facility to be decommissioned, reducing them to several aggregated criteria. Of those the most significant are the composite indicator of potential hazard and the aggregate financial indicator, taking into account the levels of their uncertainty. The proposed scheme allows finding of the optimal variant for decommissioning a nuclear facility that corresponds to the optimal correlation of criteria characterizing the maintenance of values of nuclear and radiation safety indicators and economic indicators of the decommissioned object of nuclear energy use.","PeriodicalId":211042,"journal":{"name":"2018 10th International Congress on Ultra Modern Telecommunications and Control Systems and Workshops (ICUMT)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133270084","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}
