Nowadays, embedded systems have a huge amount of computational power and consequently, high complexity. It is quite usual to find different applications being executed in embedded systems. Embedded system design demands for method and tools that allow the simulation and verification in an efficient and practical way. This paper proposes the development and evaluation of a solution for embedded modeling and simulation of heterogeneous Models of Computation (MoCs) in a distributed way by the integration of Ptolemy II and the High Level Architecture (HLA), a middleware for distributed discrete event simulation, in order to create an environment with high-performance execution of large-scale heterogeneous models. Experimental results demonstrate, that the use of a non distributed simulation for some situations can be infeasible, as well as the use of distributed simulation with few machines, like one, two or three computers. It was demonstrated that a speedup of factor 4 was acquired when a model with 4,000 thousands actors were distributed in 8 different machines.

Digital twin (DT) provides a solution for supporting the interconnection between the physical world and the virtual world. When implementing DT integration, it is challenging to implement interface definition, information and service integration across DTs. This paper proposes a semantic modeling approach with a High-Level Architecture (HLA) to support the DT integration. The semantic modeling approach based on Graph-Object-Property-Point-Role-Relationship (GOPPRR) meta-meta models is used to realize the integrated formalisms of heterogeneous DTs. HLA is used to support interface definition and service integration between virtual entities of DT. Finally, a case of an unmanned aerial vehicle (UAV) landing on ship is used to verify the flexibility of this approach. From the results, we find the GOPPRR ontology and HLA specification enables to provide a unified formalism of the DTs of UAV and the ship, and to implement data exchange during the distributed simulation execution.

MATLAB has been widely used for providing a variety of functions and tools in engineering computing, numerical analysis, modeling and visualization. In particular, through 3D animation, MATLAB has advantages for M&S (Modeling & simulation). High Level Architecture (HLA) is a general standard for interoperability and reusability in M&S. 3D animation has been used in the distributed simulations for the simulation analysis. In the distributed simulations, objects or entities continuously occur changes. Each change requires modifying its 3D animation objects or entities. It would be a problem in larger simulation environment. This paper proposes the method of an automatic-generate-3D-animation builder in MATLAB. The 3D-animation builder supports advantages of the HLA based distributed simulations. In this paper, we introduce design of a 3D-animation builder. We also present the example of an HLA-based simulation with the 3D-animation builder that could fully support the advantages of HLA simulation.

The accurate modeling of critical infrastructure systems (CISs) and their interdependencies is essential to assessing and predicting the behavior of interdependent CISs under various operation scenarios. Existing modeling approaches have limited ability to incorporate CIS domain knowledge and capture the systemic heterogeneity among the CISs, and thus cannot simulate the behavior of interdependent CISs with much detail and accuracy. In this study, a high level architecture (HLA)-based framework for modeling interdependent CISs is proposed that provides a methodology for co-simulating heterogeneous fine-grained CIS domain-specific models, reproducing with high fidelity the complex coupled systems. The results from a case study of two interdependent power and water systems revealed that the HLA-based CISs model could capture and simulate various systemic heterogeneity dimensions and their impact on the systems behavior, thus proving the efficacy of the proposed framework. © 2021 Proceedings of the International Symposium on Automation and Robotics in Construction.

The primary aim of this work is to demonstrate the feasibility of applying the High Level Architecture (HLA) framework to the distributed execution of physical urban building energy simulations that are too large to be supported within the resource constraints of a single computing node. To this end, we modify the building energy simulation tool CitySim+ to make it HLA-compliant, and use this to conduct distributed computational experiments over a small network of computing nodes. For our experiments, we consider some real-world urban models containing up to about 120,000 building surfaces. In addition to demonstrating the feasibility of our approach, the experiments further provide some performance measures to help us evaluate the appropriateness of applying the HLA in the urban simulation context. From the results of the experiments, we briefly discuss the trade-offs between the computation time and the communication and synchronization overheads involved in our distributed building energy simulation.

Development of an attack-resilient smart grid depends heavily on the availability of a representative environment, such as a Cyber Physical Security (CPS) testbed, to accelerate the transition of state-of-the-art research work to industry deployment by experimental testing and validation. There is an ongoing initiative to develop an interconnected federated testbed to build advanced computing systems and integrated data sharing networks. In this paper, we present a distributed simulation for power system using federated testbed in the context of Wide Area Monitoring System (WAMS) cyber-physical security. In particular, we have applied the transmission line modeling (TLM) technique to split a first order two-bus system into two subsystems: source and load subsystems, which are running in geographically dispersed simulators, while exchanging system variables over the internet. We have leveraged the resources available at Iowa State University's Power Cyber Laboratory (ISU PCL) and the US Army Research Laboratory (US ARL) to perform the distributed simulation, emulate substation and control center networks, and further implement a data integrity attack and physical disturbances targeting WAMS application. Our experimental results reveal the computed wide-area network latency; and model validation errors. Further, we also discuss the high-level conceptual architecture, inspired by NASPInet, necessary for developing the CPS testbed federation.

Developing an agent-based platform to monitor intelligent buildings

In recent times, significant advancements have been evidenced in efforts to enhance connectivity and security within intelligent buildings (IBs). An IB is a contemporary structure that leverages state-of-the-art computer technologies to autonomously control the environmental conditions within a building to enhance occupants' comfort, safety, work efficiency, and wellbeing while also ensuring optimal energy consumption. In the access aspect of a telecommunication network for IBs, the Main Distribution Frame (MDF) is in the central office. Intermediate Distribution Frames (IDFs) act as the isolation points for additional troubleshooting and further distribute the lines. The MDF is essentially a circuit switch that is typically operated through manual intervention because requests to establish or remove connections are sporadic and occasional. This can be tackled by utilizing Agent Based Systems (ABS) and Internet of Things (IoT) monitoring systems to develop a more holistic perspective of the process by which IDFs and MDF rooms are maintained. Furthermore, it will generate a process overview if we eradicate the process of physically checking a room that is currently used for IoT monitoring. In this research, a case study is presented to determine the feasibility of developing an IoT monitoring system. Currently, the monitoring applied in the case study is long, and over 40% of the equipment has maintenance failures. distributed simulation of ABS is used to simulate the use of IoT for this project. Its data forecast can be very useful in determining the appropriate actions to improve the process of IDF and MDF and operational cost.

PDES-MAS: distributed simulation of Multi-agent Systems

Procedia Computer Science 2013年 18卷 671-681页

作者： Vinoth Suryanarayanan Georgios Theodoropoulos Michael Lees School of Computer Science University of Birmingham UK Institute of Advanced Research Computing Durham University UK School of Computer Engineering Nanyang Technological University Singapore

Multi-agent systems (MAS) are increasingly being acknowledged as a modelling paradigm for capturing the dynamics of complex systems in a wide range of domains, from system biology to adaptive socio-technical system of systems. The execution of such MAS simulations on parallel machines is a challenging problem due to their dynamic, non-deterministic, data-centric behaviour and nature. These problems are exacerbated as the scale of such MAS models increases. PDES-MAS is a distributed simulation kernel developed specifically to support MAS models addressing the problems of partitioning, load balancing and interest management in an integrated, transparent and adaptive manner. This paper presents an overview of PDES-MAS and for the first time it provides a quantitative evaluation of the system.

Toward scalable cloud data center simulation using high-level architecture

Existing simulators are designed to simulate a few thousand nodes due to the tight integration of modules. Thus, with limited simulator scalability, researchers/developers are unable to simulate protocols and algorithms in detail, although cloud simulators provide geographically distributed data centers environment but lack the support for execution on distributed systems. In this paper, we propose a distributed simulation framework referred to as CloudSimScale. The framework is designed on top of highly adapted CloudSim with communication among different modules managed using IEEE Std 1516 (high-level architecture). The underlying modules can now run on the same or different physical systems and still manage to discover and communicate with one another. Thus, the proposed framework provides scalability across distributed systems and interoperability across modules and simulators.
