The investigation and the development of self-organizing systems are especially needed for operation and control in massively distributed systems such as Sensor and Actor Networks (SANETs). The main issues addressed by self-organization techniques are scalability, network lifetime, and real-time support. In the literature, biological principles are often(More)
We describe model-level unit tests for model-driven simulation based on UML models. We refer to the well-known unit testing method and apply this concept on a higher abstraction level, that is on UML simulation models. The concept of model-based simulation has become more and more popular throughout the last years. This trend is fostered by the availability(More)
We describe a programming scheme for massively distributed systems that are assumed to self-organize according to a given set of simple rules. The focus of this investigation is operation and control in sensor and actor networks (SANETs). The main issues addressed by self-organization techniques are scalability, network lifetime, and real-time support. In(More)
Mobile Ad Hoc Networks (MANETs) have evolved in the last years into standards in the communication world. By definition, they do not need any network infrastructure to facilitate communication between participating nodes. Therefore , MANETs are dealing with new challenges in the context of ad hoc routing. Simulation techniques are one of the fundamental(More)

By definition, they do not need any network infrastructure to facilitate communication between participating nodes. Therefore , they are dealing with new challenges in the context of ad hoc routing.

In this paper, we discuss the need for using standardized graphical modeling languages for developing and evaluating simulation models. In particular, we use UML 2 diagrams to construct simulation models to be executed in an event-driven simulation framework (currently, we are using OMNeT++). The translation of the UML 2 models is provided by(More)
Simulation is frequently used to evaluate the performance of networking algorithms and techniques in wireless communication networks. However, performance aspects such as the transmission delay, the channel utilization, or the through-put provide only limited information about the feasibility of the particular approach. This is especially the case when(More)
