Complex technical systems like robots or cars are composed of many embedded subsystems to control partial dynamical effects of the whole system. In order to ease engineering and to cope with changing environmental or system properties, these subsystems need to be self-adapting. But for this to be feasible, they cannot observe the theoretically required state space of the whole system. Instead, the...Show More
An efficiency improvement advisor agent acts as a consultation service for a self-organizing multi-agent system that improves operational efficiency. It identifies recurrent tasks in past problems that allow the creation of so-called exception rules for individual agents to limit future inefficient behavior. There exists the danger that introduced rules could possibly infringe on the flexibility a...Show More
Spatial publish subscribe (SPS) is a basic primitive underlying many real-time, interactive applications such as online games or discrete-time simulations. Supporting SPS on a large-scale, however, requires sufficient resources and proper load distribution among the simulation units. For load distribution, existing mechanisms either use a static partitioning, such that over-provisioning or overloa...Show More
It is generally foreseen that the number of wirelessly connected networking devices will increase in the next decades, leading to a rise in the number of applications involving large-scale networks. A major building block for enabling self-* system properties in ad-hoc scenarios is the run-time discovery of neighboring devices and somewhat equivalently, the estimation of the local node density. Th...Show More
The area of self-stabilization in large scale networks has been received increasing attention among researchers, since self-stabilization provides a foundation for self-properties, including self-healing, self-organizing and self-adaptive. This paper makes contributions in two areas. First, we describe a new extended approach of self-stabilization, called self-stabilization with service guarantee....Show More
For problems that cannot be modeled and solved efficiently using a centralized approach, distributed algorithms are a necessity. Self-organizing systems are systems constructed from a network of autonomous communicating agents whereby from simple individual behaviors emerges a global system behavior that is complex, efficient, adaptable, and robust. For the right behavior to emerge, the components...Show More
Pervasive applications incorporate physical components that are exposed to everyday use and a large number of conditions and external factors that can lead to faults and failures. It is also possible that application requirements change during deployment and the network needs to adapt to a new context. Consequently, pervasive systems must be capable to autonomically adapt to changing conditions wi...Show More
Organic Computing Systems feature self-organizing techniques to manage the rising complexity of distributed systems. This paper introduces an implementation of self-configuration, self-healing and self-optimization by means of an Organic Manager. The Organic Manager is based on an automated planner and integrated in a middleware. The Organic Manager unites formerly distributed self-x features to u...Show More
While there has been considerable work on self-adaptive systems, applying these techniques to networked, embedded systems poses several new problems due to the requirements of embedded real-time systems. Among others, we have to consider memory and hardware limitations, as well as task schedulability and timing dependencies. The goal of this paper is to find a correct placement of software compone...Show More
In recent years it has become more and more evident that openness and adaptivity are key characteristics of next generation distributed systems. The reason for that is not least the advent of computing trends like Ubiquitous Computing, Ambient Intelligence, and Cyber Physical Systems, where systems are usually open for dynamic integration and able to react adaptively to changing situations. Despit...Show More
An essential requirement for the operation of self-adaptive systems is information about their internal health state, i.e., the extent to which the constituent software and hardware components are still operating reliably. Accurate health information enables systems to recover automatically from (intermittent) failures in their components through selective restarting, or self-reconfiguration. This...Show More
The behaviour of self-* systems is complex to model from an algorithmic point of view. Designing and specifying self-* systems implies a great amount of work that can be sensibly reduced if models can be reused and composed in a modular way. This article discusses a chemically-inspired architecture and formalisms that facilitate the creation of modular, reusable models based on behavioural pattern...Show More
The goal of this work is to gain a better understanding of the role that inter-agent variation plays in self-organizing systems. We develop both continuous and discrete models of a multi-agent coordination procedure based on response thresholds and use these models to analyze the average behavior of a system as well as examine the dynamics of single instances of the problem. Results indicate that ...Show More
Since a couple of years, multi-agent systems have been used for a wide range of applications such as problem solving, modelling and simulation, Reactive agent based systems are characterized by their capability to solve complex problems, while maintaining functional and conceptual simplicity of each element. These approaches exhibit effectiveness whatever the considering fields (life simulation, r...Show More
