An increased mobility and the resulting rising traffic demands lead to serious congestion problems in many cities. Although there is not a single solution that will solve traffic congestion and the related environmental and economical problems, traffic light coordination is an important factor in achieving efficient networks. This paper presents a new(More)
In recent years, Smart Camera Networks are a field of intensive research, because of the versatile application areas of such systems. This work contributes to realize such applications by focusing on the problem of optimizing the coverage in a pan tilt zoom (PTZ) camera network during runtime. We propose to approach this problem with Reinforcement Learning(More)
Cloud Computing allows the on-demand usage of computing resources in a pay-as-you-use manner. One major problem for Cloud providers is the trade-off between the huge amount of energy consumption resulting from the non optimal utilisation of their servers, and meeting the service level agreements. Virtualisation allows for a better utilisation of existing(More)
In recent years, autonomic and organic computing have become areas of active research in the informatics community. Both initiatives aim at handling the growing complexity in technical systems by focusing on adaptation and self-optimisation capabilities. A promising application for organic concepts is the control of road traffic signals in urban areas. This(More)
Networked systems are becoming increasingly complex in development and operation. Due to this complexity, it is mostly impossible to follow a simple sequential designdeploy-use cycle. Instead, development and operation will become more evolutionary in nature. Additionally, one can observe that individual complex systems are coupled with each other, even(More)
Due to steadily increasing mobility and the resulting rising traffic demands, serious congestion problems can be observed in many cities. One promising approach to alleviate the congestion effects is the coordination of the network's traffic signals in response to the traffic flow. The recently introduced Decentralised Progressive Signal Systems approach is(More)
Current trends in information and communication technology show that systems are increasingly influencing each other – which is seldom completely anticipated at design-time. As a result, mastering system integration with traditional methods becomes infeasible due to the resulting complexity. In this paper we argue that self-improving system integration is(More)
