When it comes from an experimental measurement, the timing of these events has a limited precision. This precision is usually well-known and documented for each instruments and procedures used for collecting experimental datas. Therefore, these instruments and procedures produce measurement results expressed using values each associated with an uncertainty quantification, given by uncertainty intervals. Tools have been developed in Continuous Systems modeling for deriving the uncertainty intervals of the final results corresponding to the propagation of the uncertainty intervals being evaluated. These tools cannot be used in DES as they are defined, and no alternative tools that would apply to DES have been developed yet. In this paper, we propose simulation algorithms, based on the Discrete Event System Specification (DEVS) formalism, that can be used to simulate and obtain every possible output and state trajectories of simulations that receive input values with uncertainty quantification. Then, we present a subclass of DEVS models, called Finite Forkable DEVS (FF-DEVS), that can be simulated by the proposed algorithms. This subclass ensures that the simulation is forking only a finite number of processes for each simulation step. Finally, we discuss the simulation of a traffic light model and show the trajectories obtained when it is subject to input uncertainty.","PeriodicalId":132237,"journal":{"name":"International ICST Conference on Simulation Tools and Techniques","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122713346","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}

In this paper, we propose a generic approach to modeling the performance of data center networks. The approach offers multiple performance models but requires to use only a single modeling language. We propose a two-step modeling methodology, in which a high-level descriptive model of the network is built in the first step, and in the second step model-to-model transformations are used to automatically transform the descriptive model to different network simulation models. We automatically generate three performance models defined at different levels of abstraction to analyze network throughput. By offering multiple simulation models in parallel, we provide flexibility in trading-off between the modeling accuracy and the simulation overhead. We analyze the simulation models by comparing the prediction accuracy with respect to the simulation duration. We observe, that in the investigated scenarios the solution duration of coarser simulation models is up to 300 times shorter, whereas the average prediction accuracy decreases only by 4 percent.","PeriodicalId":132237,"journal":{"name":"International ICST Conference on Simulation Tools and Techniques","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126980478","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}

While visual languages have many advantages, they may not be appropriate to render all details of a Discrete EVent system Specification (DEVS) model. Textual may be more appropriate, both to completely describe all details of a DEVS model (i.e., the content of transition and output functions), and to make the specification independent of the implementation platform (i.e., simulation implementation language). \u0000 \u0000In this paper, we propose two textual notations that are used as part of an integrated modelling and simulation environment for the Parallel DEVS formalism. Both notations allow the specification of DEVS functions by means of neutral action code. DEVSPro uses Python-like textual syntax and supports the full power of Parallel DEVS. From this neutral specification, simulator-specific code is synthesized. DEVSLang supports blended textual/visual modelling. It is more restricted in expressiveness to match the limited expressiveness of visual notations. For example, the sequential states in an Atomic model must be explicitly enumerated. \u0000 \u0000Visual DEVSLang models are transformed to their textual form in order to carry out syntactic and semantic checks. Possible detected errors are fed back to the visual modelling environment allowing the modeller to make changes directly in the source model. DEVSLang models are further translated automatically to DEVSPro models to allow for possible combination with DEVSPro models and subsequent analysis and simulation.","PeriodicalId":132237,"journal":{"name":"International ICST Conference on Simulation Tools and Techniques","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115624715","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}

In the domain of networked control systems, the medium of communication is increasingly involving wireless communication along-side conventional wired communication. Issues ranging from energy efficiency and reliability to low-bandwidth have to be addressed to enable the transition to increased use of wireless communication. In earlier work, we have proposed the Dual-Mode Adaptive MAC (DMAMAC) protocol relying on a combination of Time Division Multiple Access (TDMA) and Carrier Sense Multiple Access (CSMA). The DMAMAC protocol is able to dynamically adapt to the two main states found in process control: the steady state and the transient state. Key requirements to the DMAMAC protocol are energy efficiency, low probability of state-switch failures, and a low state-switch delay. \u0000 \u0000The contribution of this paper is a comprehensive simulation-based evaluation of the original DMAMAC protocol along with the evaluation of a new pure TDMA-based variant of the DMAMAC protocol. Our results show that for processes where the steady state dominates, both variants of the DMAMAC protocol can reduce energy consumption by up to 45% in comparison to the closely related single-mode GinMAC protocol. Among the two variants of DMAMAC, the pure TDMA-based variant has the better energy efficiency and higher reliability. The simulation results also show that the hybrid TDMA-CSMA variant of the DMAMAC protocol has a probability of less than 0.3% for a state-switch failure in a given MAC superframe. The simulation study has impacted the design of the DMAMAC protocol by providing insights that have led to design changes in the originally proposed DMAMAC protocol in order to further reduce the state-switch delay between the steady and the transient state.","PeriodicalId":132237,"journal":{"name":"International ICST Conference on Simulation Tools and Techniques","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116735006","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}

Due to the heterogeneous environment consisting of both, mobile and fixed devices, a multitude of effects on different scales need to be considered. Microscopic effects, such as an individual user's interaction with the device, as well as macroscopic effects, such as scalability with the number of users have an impact on the system's performance. The combined evaluation of micro- and macroscopic effects requires both, simulations and prototypical deployments. Furthermore, insights obtained through prototypes during user studies can lead to refined protocols and algorithms, thereby contributing to the overall design process. To enable parallel assessment of micro- and macroscopic effects, we propose the Simonstrator platform, consisting of a lightweight framework for the development and instrumentation of distributed systems as well as runtime environments for (i) the interaction with common simulators, (ii) the deployment on testbeds, and (iii) Android devices. The platform is specifically targeted towards distributed systems for heterogeneous scenarios, considering mobile and fixed networks. We show sample simulations and prototypical deployments of two exemplary use cases: a live video streaming system and a middleware for augmented reality games, highlighting different evaluation goals and environments supported by the proposed Simonstrator platform.","PeriodicalId":132237,"journal":{"name":"International ICST Conference on Simulation Tools and Techniques","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114989081","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}
