Organic Self-organizing Bus-based Communication Systems

今天的电子系统由许多复杂的组件组成，这些组件通过通信网络和总线系统相互作用。在这个项目中，研究了一种基于总线的通信系统分析、设计和优化的有机方法。我们的方法的目标是克服当今纯离线设计的缺点，这些缺点基于最坏情况估计，不可扩展，并且在运行时环境或需求发生变化时很容易退化。相比之下，使用在线自组织的分散方法将能够监控通信系统的实际流量，并相应地调整发送速率、概率、优先级等。该项目旨在提供a)基于博弈论和效用函数的基于总线的通信体系结构自组织的理论基础，b)模型以及设计方法，包括实现冲突需求（如截止日期和带宽）的这些属性的学习技术，以及c)仿真试验台。最后，d)应开发硬件演示器，以便在现实环境中证明所研究方法的好处。

Today s electronic systems comprise a multitude of complex components interacting over communication networks and bus systems. In this project, an organic approach for the analysis, design and optimization of bus-based communication systems is investigated. The goal of our approach is to overcome drawbacks of today s pure offline designs that are based on worst-case estimations, are not expandable, and may easily degenerate when the environment or requirements change at run-time. In contrast, a decentralized approach using online self-organization would be able to monitor the actual traffic ofthe communication system and adapt either sending rates, probabilities, priorities, etc. accordingly. This project intends to provide a) theoretical foundations on self-organization for bus-based communication architectures based on game theory and utility functions, b) models as well as a design methodology including learning techniques to implement such properties for conflicting requirements, such as deadlines and bandwidth, and c) a simulation testbed. Finally, d) a hardware demonstrator shall be developed in order to prove the benefits of the investigated approaches in a realistic environment.
