This project aims for a measurement-based approach towards composable models for CPNs. We plan to set up a measurement testbed, that supports the evaluation of a CPN benchmark application using reproducible measurements of different wireless technologies and protocol stacks. Our approach is to use a two-wheeled inverted pendulum (TWIP), of which a Segway is a well-known instantiation, as benchmark example. This software emulation can be evaluated in combination with a variety of wireless protocol stack alternatives in an automated measurement series.We analyze the protocol stack in detail, using composable models that we parameterize using the measurement results. Network calculus provides a framework that allows for combining performance models. Stochastic Network Calculus allows to give stochastic performance bounds on delays. Temporal network calculus allows to model the impact of error-prone wireless links and contention-based multi-access networks on latency. We investigate the influence of the software stack execution on the network service quality by different processing platforms. For effective collaboration with other projects of the Priority Program "Cyber-Physical Networking", we will make the measurement data generated in the testbed publicly available.

该项目的目的是对CPNs的组合模型的测量为基础的方法。我们计划建立一个测量测试平台，支持使用不同的无线技术和协议栈的可重复测量的CPN基准应用程序的评估。我们的方法是使用一个两轮倒立摆（Tendon），其中赛格威是一个众所周知的实例，作为基准的例子。该软件仿真可以结合各种无线协议栈的替代品进行评估，在一个自动化的测量series.We详细分析了协议栈，使用组合模型，我们使用测量结果parameterized。网络演算提供了一个框架，允许组合性能模型。随机网络演算允许给随机性能界的延迟。时间网络演算允许对易出错的无线链路和基于竞争的多路访问网络对延迟的影响进行建模。我们研究了不同处理平台下软件栈执行对网络服务质量的影响。为了与优先计划“网络物理网络”的其他项目进行有效合作，我们将公开测试平台中生成的测量数据。
