Approximate Distributed Discrete Event Simulation using Semi-Conservative Look-Ahead Estimation 基于半保守预估的近似分布离散事件模拟
Desheng Fu, Marcus O'Connor, Matthias Becker, H. Szczerbicka
A novel way of distributed discrete event simulation, called approximate distributed discrete event simulation, is presented in this paper. Compared with the classic simulation, the models for approximate simulation give some kind of free margin to the simulator during the execution. This can be used in some cases to reduce the overhead of the simulation, especially the execution time. Since the margin can be adjusted arbitrarily in the range, a trade-off between the simulation precision and the execution time can be achieved this way. It’s well known that the execution time of distributed discrete event simulation can’t be reduced significantly compared with a sequential simulation when the logical processes are tightly coupled and the lookahead is very short. In this study, a framework of approximate distributed discrete event simulation with some novel algorithms is developed, which is aimed to provide a longer look-ahead and further the trade-off between the simulation precision and the execution time using the free margin provided by the model.
本文提出了一种新的分布式离散事件模拟方法——近似分布离散事件模拟。与经典仿真相比,近似仿真模型在仿真过程中给仿真器提供了一定的自由余地。这可以在某些情况下用于减少模拟的开销,特别是执行时间。由于余量可以在这个范围内任意调整,因此可以通过这种方式在模拟精度和执行时间之间进行权衡。众所周知,在逻辑过程紧密耦合且前瞻时间很短的情况下,分布式离散事件仿真的执行时间与序列仿真相比不能显著缩短。本文提出了一种基于新算法的近似分布离散事件仿真框架,该框架旨在利用模型提供的自由余量提供更长的前瞻性,并进一步权衡仿真精度和执行时间之间的关系。

Media and non-media WebRTC communication between a terrestrial station and a drone: the case of a flying IoT system to monitor parking 地面站和无人机之间的媒体和非媒体WebRTC通信:以飞行物联网系统监控停车为例
A. Chodorek, R. Chodorek, K. Wajda
In this paper we propose a flying IoT system designed to monitor parking lot. The system is composed of a flying mobile station and a terrestrial station. The mobile station consists of visual monitoring camera associated with air quality monitoring sensors, mounted on a Turnigy SK450 quad copter controlled with Pixhawk autopilot hardware. Data gathered from the monitoring system are transmitted to an IoT broker running on a Raspberry Pi 3+ microcontroller, also mounted on a drone, that aggregates data into a common flow and retransmits them to the terrestrial station. The transmission system was build according to WebRTC architecture. In order to assure separation of the production network (for transmission of application data) and the management network (for management and control purposes), two different transmission channels are used: one for the WebRTC transmission and the other for controlling the drone. The paper includes a description of the system and the results of field trials carried out on the parking lot of the AGH University of technology.
本文提出了一种用于监控停车场的飞行物联网系统。该系统由一个飞行移动站和一个地面站组成。移动站包括与空气质量监测传感器相关的视觉监控摄像头,安装在Turnigy SK450四轴直升机上,由Pixhawk自动驾驶仪硬件控制。从监测系统收集的数据被传输到运行在树莓派3+微控制器上的物联网代理,该微控制器也安装在无人机上,该代理将数据聚合成一个公共流,并将其重新传输到地面站。传输系统采用WebRTC架构构建。为了保证生产网络(用于传输应用数据)和管理网络(用于管理和控制)的分离,使用了两个不同的传输通道:一个用于WebRTC传输,另一个用于控制无人机。本文介绍了该系统的基本情况和在AGH理工大学停车场进行的现场试验结果。

Human Mobility Simulator for Smart Applications 智能应用的人类移动模拟器
A. D. Paola, A. Giammanco, G. Re, M. Morana
Several issues related to Smart City development require the knowledge of accurate human mobility models, such as in the case of urban development planning or evacuation strategy definition. Nevertheless, the exploitation of real data about users’ mobility results in severe threats to their privacy, since it allows to infer highly sensitive information. On the contrary, the adoption of simulation tools to handle mobility models allows to neglect privacy during the design of location-based services. In this work, we propose a simulation tool capable of generating synthetic datasets of human mobility traces; then, we exploit them to evaluate the effectiveness of algorithms which aim to detect Points of Interest visited by users of a Smart Campus. Our simulator exploits an activity-based mobility model, thus it is based on the assumption that mobility of campus users is motivated by the activities they plan to perform. It is capable of simulating the weekly repetitiveness of human behavior and to model different mobility profiles for each day of the week through a fifth-order Markov model.
与智慧城市发展相关的几个问题需要准确的人类移动模型知识,例如城市发展规划或疏散策略定义。然而,利用用户移动的真实数据会对他们的隐私造成严重威胁,因为它允许推断高度敏感的信息。相反,采用仿真工具来处理移动模型可以在基于位置的服务设计过程中忽略隐私。在这项工作中,我们提出了一种能够生成人类移动轨迹合成数据集的模拟工具;然后,我们利用它们来评估算法的有效性,这些算法旨在检测智能校园用户访问的兴趣点。我们的模拟器利用了一个基于活动的移动性模型,因此它是基于校园用户的移动性是由他们计划执行的活动驱动的假设。它能够模拟人类行为的每周重复性,并通过五阶马尔可夫模型为一周中的每一天建模不同的移动概况。

Distributed Simulation of Crowds with Groups in CrowdSim CrowdSim中群体的分布式模拟
M. Abadeer, S. Gorlatch
Simulating large crowds of individuals is socially important, e.g., for developing and studying evacuation or rescuing in dangerous situations. Such simulations remain complex due to the scalability challenge: simulating thousands of virtual characters is computationally expensive, especially when taking into account psychological factors and group-specific behavior that play a crucial role, e.g., in panic situations and highly crowded environments. In this paper, we make two new contributions: 1) we extend the HiDAC agent-based modeling approach with the aspects of group formation and movement, and 2) we implement our approach within the CrowdSim system, including the possibility to distribute the simulation process across several compute servers for better performance. We report experimental results on scaling the distributed simulation of a real-world evacuation scenario in a building using several compute servers.
模拟大量个体在社会上具有重要意义,例如,对于制定和研究危险情况下的疏散或救援。由于可扩展性的挑战,这样的模拟仍然很复杂:模拟数千个虚拟角色在计算上是昂贵的,特别是当考虑到心理因素和群体特定行为起着至关重要的作用时,例如,在恐慌的情况下和高度拥挤的环境中。在本文中,我们做出了两个新的贡献:1)我们扩展了基于HiDAC代理的建模方法,包括群体形成和运动方面;2)我们在CrowdSim系统中实现了我们的方法,包括在多个计算服务器上分布仿真过程以获得更好的性能的可能性。我们报告了使用多个计算服务器扩展建筑物中真实疏散场景的分布式模拟的实验结果。

Evaluation of the Energy Consumption Model Performance for Electric Vehicles in SUMO 相扑比赛中电动汽车能耗模型性能评价
Insaf Sagaama, Amine Kchiche, Wassim Trojet, F. Kamoun
In recent years, the diffusion of electric vehicles(EVs) is of great importance in the road transport and automotive sectors. Reducing electricity consumption and increasing battery autonomy are actually motivating vehicle manufacturers to focus their attention on the EV concept. The evaluation of EV performance through realistic scenarios in traffic simulations is still a key issue. In fact, the road traffic Simulator Simulation of Urban Mobility (SUMO) integrates an energy model for calculating the EV energy consumption. However, this model underestimates the energy consumption values in the real world. In this paper, we intend to investigate the energy consumption models existing in the literature. Then, we assess the performance of the existing energy model in SUMO through a set of simulation scenarios. Finally, we present the main requirements for a realistic, accurate and scalable energy model to estimate the instantaneous energy consumption for EVs.
近年来,电动汽车(ev)的普及在道路运输和汽车行业具有重要意义。减少电力消耗和提高电池自主性实际上是促使汽车制造商将注意力集中在电动汽车概念上。在交通仿真中,通过真实场景对电动汽车的性能进行评估仍然是一个关键问题。实际上,道路交通模拟器仿真城市交通(SUMO)集成了一个能量模型来计算电动汽车的能耗。然而,这个模型低估了现实世界的能源消耗值。在本文中,我们打算对文献中存在的能源消耗模型进行研究。然后,我们通过一组仿真场景来评估现有能量模型在相扑中的性能。最后,我们提出了一个真实、准确和可扩展的能量模型来估计电动汽车的瞬时能量消耗的主要要求。

Multi-rate DAG Scheduling Considering Communication Contention for NoC-based Embedded Many-core Processor 考虑通信竞争的嵌入式多核处理器多速率DAG调度
Shingo Igarashi, Yuto Kitagawa, Tasuku Ishigooka, Tatsuya Horiguchi, Takuya Azumi
Computing platforms for embedded systems are increasingly being transformed into multi/many-core platforms because embedded systems have become extensive, complex, and automated. In the case of an autonomous driving system, various applications are simultaneously running, and low power consumption and large-scale calculation are required. Many-core processors with a multiple instruction, multiple data (MIMD) architecture can meet these requirements. This paper proposes a scheduling algorithm for an automotive driving system expressed in a directed acyclic graph (DAG) and we use Kalray MPPA-256 as the target many-core processor. On the basis of the architecture of Kalray MPPA-256, task processing that requires large-scale calculation and intercore communication is performed while avoiding communication contention by using a proposed grouping computational resource. In addition, we propose a scheduling method for a multi-rate DAG which is a DAG with multiple periods. This method generates a DAG task in a hyperperiod and schedules the DAG with dependency on tasks that have been released closely. The formulas for prioritization and processor selection are proposed for various generated tasks in a hyperperiod. Evaluation results show that the proposed algorithm is superior to existing DAG scheduling algorithms with regard to schedulability and deadline miss ratio.
由于嵌入式系统已变得广泛、复杂和自动化,嵌入式系统的计算平台正日益向多核/多核平台转变。在自动驾驶系统中,各种应用程序同时运行,需要低功耗和大规模计算。采用多指令多数据(MIMD)架构的多核处理器可以满足这些要求。本文提出了一种用有向无环图(DAG)表示的汽车驾驶系统调度算法,并以Kalray MPPA-256为目标多核处理器。在Kalray MPPA-256架构的基础上,利用分组计算资源避免了通信争用,完成了需要大规模计算和核间通信的任务处理。此外,我们还提出了一种多速率DAG的调度方法,即具有多个周期的DAG。此方法在超周期中生成DAG任务,并将DAG与已紧密释放的任务的依赖关系进行调度。提出了超周期内各种生成任务的优先级和处理器选择公式。评价结果表明,该算法在可调度性和最后期限缺失率方面优于现有的DAG调度算法。

The Infinity Computer for Optimization and Not Only 无限计算机的优化和不只是
Y. Sergeyev
In this lecture, a recent computational methodology is described. It has been introduced with the intention to allow one to work with infinities and infinitesimals numerically in a unique computational framework. It is based on the principle ‘The part is less than the whole’ applied to all quantities (finite, infinite, and infinitesimal) and to all sets and processes (finite and infinite). The methodology uses as a computational device the Infinity Computer (patented in USA and EU) working numerically with infinite and infinitesimal numbers that can be written in a positional system with an infinite radix. On a number of examples (numerical differentiation, divergent series, ordinary differential equations, fractals, set theory, etc.) it is shown that the new approach can be useful from both theoretical and computational points of view. The main attention is dedicated to applications in optimization (local, global, and multi-objective). The accuracy of the obtained results is continuously compared with results obtained by traditional tools used to work with mathematical objects involving infinity. The Infinity Calculator working with infinities and infinitesimals numerically is shown during the lecture. For more information see http://www.theinfinitycomputer.com and this survey: Sergeyev Ya.D.

在这个讲座中,描述了一种最新的计算方法。它被引入的目的是允许人们在一个独特的计算框架中处理无穷大和无穷小的数值。它基于“部分小于整体”的原则,适用于所有的量(有限的、无限的和无穷小的),适用于所有的集合和过程(有限的和无限的)。该方法使用无限计算机(在美国和欧盟获得专利)作为计算设备,对无限和无限小的数字进行数值处理,这些数字可以用无限基数的位置系统来书写。通过数值微分、发散级数、常微分方程、分形、集合论等实例,证明了该方法在理论和计算上的实用性。主要关注在优化(局部、全局和多目标)方面的应用。所得到的结果的准确性不断地与用于处理涉及无穷大的数学对象的传统工具所得到的结果进行比较。无限计算器将在讲座中展示如何处理无穷和无穷小的数值。欲了解更多信息,请访问http://www.theinfinitycomputer.com和此调查:Sergeyev yad。数值无穷大与无穷小:两个Hilbert问题的方法论、应用及其影响,数学科学EMS调查,2017,4(2),219-320。欲了解更多信息,请访问http://www.theinfinitycomputer.com和此调查:Sergeyev yad。数值无穷大与无穷小:两个Hilbert问题的方法论、应用及其影响,数学科学EMS调查,2017,4(2),219-320。

From Sensors to the Cloud: a Real-Time Use-case on Vertical Integration 从传感器到云:垂直集成的实时用例
Giuseppe Portaluri, Marialaura Tamburello, S. Giordano
We present a vertical integration of a real-time Industrial Internet of Things environment with Cloud computing functionalities. We designed our testbed to implement self-adaptive wings for motorbikes using pressure values sensed in specific locations of the motorbike as input data collected exploiting open-hardware devices called OpenMotes which communicate through a low-power, delay-constrained wireless network based on the 6LoWPAN protocol stack. Our real-time on-board unit elaborates the data, and it computes the new angle of attack of two wings. The total response time of the system is in the order of 100 ms and meets the real-time requirements that constrains our scenario. Finally, we integrate our system with Cloud functionalities that we use for storing the acquired data on a time-series database.
我们提出了一个实时工业物联网环境与云计算功能的垂直整合。我们设计了一个测试平台来实现摩托车的自适应机翼,使用在摩托车特定位置感知的压力值作为输入数据,利用称为OpenMotes的开放硬件设备,通过基于6LoWPAN协议栈的低功耗、延迟限制的无线网络进行通信。我们的实时机载单元详细阐述了这些数据,并计算了机翼的新攻角。系统的总响应时间在100毫秒左右,满足了我们场景的实时性要求。最后,我们将我们的系统与云功能集成,我们使用云功能将获取的数据存储在时间序列数据库中。

We designed our testbed to implement self-adaptive wings for motorbikes using pressure values sensed in specific locations of the motorbike as input data collected exploiting open-hardware devices called OpenMotes which communicate through a low-power, delay-constrained wireless network based on the 6LoWPAN protocol stack. Our real-time on-board unit elaborates the data, and it computes the new angle of attack of two wings.
