An anomaly detection framework integrated in a real-time operating system can ease the identification of such suspicious novel behavior and, thereby, offers the potential to enhance the reliability of the considered self-x system. However, anomaly detection is based on knowledge about normal behavior. When dealing with self-reconfiguring applications, normal behavior changes. Hence, knowledge base requires adaptation or even re-construction at runtime. The stringent restrictions of real-time systems considering runtime and memory consumption make this task to a really challenging problem. We present our idea for online construction of application behavior knowledge that does not rely on training phase. The applications' behavior is defined by the application's system call invocations. For the knowledge base, we exploit suffix trees as they offer potentials to represent application behavior patterns and associated information in a compact manner. The online algorithm provided by suffix trees is a basis to construct the knowledge base with low computational effort. Anomaly detection and classification is integrated into the online construction method. New behavioral patterns do not unconditionally update the behavior knowledge base. They are evaluated in a context-related manner inspired by Danger Theory, a special discipline of artificial immune systems.

In cellular networks, however, the unreliable wireless channel leads to two major problems. Poor channel states degrade video quality and interrupt the playback when a user cannot sufficiently fill its local playout buffer: buffer underruns occur. In contrast, good channel conditions cause common greedy buffering schemes to buffer too much data. Such over-buffering wastes expensive wireless channel capacity. Assuming that we can anticipate future data rates, we plan the quality and download time of video segments ahead. This anticipatory download scheduling avoids buffer underruns by downloading a large number of segments before a drop in available data rate occurs, without wasting wireless capacity by excessive buffering.We developed a practical anticipatory scheduling algorithm for segmented video streaming protocols (e.g., HLS or MPEG DASH). Simulation results and testbed measurements show that our solution essentially eliminates playback interruptions without significantly decreasing video quality."}],"status":"public","file":[{"access_level":"closed","file_name":"252-DBDVK15.pdf","file_id":"1488","file_size":587685,"date_created":"2018-03-21T09:44:45Z","creator":"florida","date_updated":"2018-03-21T09:44:45Z","relation":"main_file","success":1,"content_type":"application/pdf"}],"publication":"Proceedings of the 2nd International Conference on Networked Systems (NetSys)","type":"conference","ddc":["040"],"file_date_updated":"2018-03-21T09:44:45Z","_id":"252","department":[{"_id":"75"}],"user_id":"15572"},{"publication":"Proceedings of the Sixth International Conference on Mathematical Aspects of Computer and Information Sciences (MACIS)","abstract":[{"text":"Group signatures, introduced by Chaum and van Heyst [15], are an important primitive in cryptography.

Our objective is to develop and to investigate closely linked symbiotic relationships between robots and natural plants and to explore the potentials of a plant-robot society able to produce architectural artifacts and living spaces. These robot-plant bio-hybrids create synergies that allow for new functions of plants and robots. They also create novel design opportunities for an architecture that fuses the design and construction phase. The bio-hybrid is an example of mixed societies between 'hard' artificial and 'wet' natural life, which enables an interaction between natural and artificial ecologies. They form an embodied, self-organizing, and distributed cognitive system which is supposed to grow and develop over long periods of time resulting in the creation of meaningful architectural structures. A key idea is to assign equal roles to robots and plants in order to create a highly integrated, symbiotic system.

These approaches require the definition of a behavioral distance, which often includes task-specific features and hence a priori knowledge. Alternative methods, which do not explicitly force selective pressure towards diversity (SPTD) but still generate it, are known from the field of artificial life, such as in artificial ecologies (AEs). In this study, we investigate how SPTD is generated without task-specific behavioral features or other forms of a priori knowledge and detect how methods of generating SPTD can be transferred from the domain of AE to ER. A promising finding is that in both types of systems, in systems from ER that generate behavioral diversity and also in the investigated speciation model, selective pressure is generated towards unpopulated regions of search space. In a simple case study we investigate the practical implications of these findings and point to options for transferring the idea of self-organizing SPTD in AEs to the domain of ER.","lang":"eng"}],"status":"public","_id":"19962","user_id":"15415","department":[{"_id":"63"},{"_id":"238"}],"language":[{"iso":"eng"}]},{"abstract":[{"lang":"eng","text":"Aggregation is a crucial task in swarm robotics to ensure cooperation.

Potentially, the complexity of evolving a successful controller for a given task can be reduced by integrating a priori knowledge into the fitness function which complicates the comparability of studies in evolutionary robotics. Still, there are only few publications that study the actual effects of different fitness functions on the robot's performance. In this paper, we follow the fitness function classification of Nelson et al. (2009) and investigate a selection of four classes of fitness functions that require different degrees of a priori knowledge. The robot controllers are evolved in simulation using NEAT and we investigate different tasks including obstacle avoidance and (periodic) goal homing. The best evolved controllers were then post-evaluated by examining their potential for adaptation, determining their convergence rates, and using cross-comparisons based on the different fitness function classes. The results confirm that the integration of more a priori knowledge can simplify a task and show that more attention should be paid to fitness function classes when comparing different studies.","lang":"eng"}],"status":"public","publication":"Proceedings of the Genetic and Evolutionary Computation Conference (GECCO 2015)","type":"conference"},{"_id":"19988","user_id":"15415","department":[{"_id":"63"},{"_id":"238"}],"language":[{"iso":"eng"}],"type":"conference","publication":"13th European Conference on Artificial Life (ECAL 2015)","status":"public","publisher":"MIT Press","date_updated":"2022-01-06T06:54:17Z","author":[{"first_name":"Heiko","last_name":"Hamann","full_name":"Hamann, Heiko"},{"first_name":"Thomas","last_name":"Schmickl","full_name":"Schmickl, Thomas"},{"first_name":"Payam","last_name":"Zahadat","full_name":"Zahadat, Payam"}],"date_created":"2020-10-13T08:50:38Z","title":"Evolving Collective Behaviors With Diverse But Predictable Sensor States","doi":"10.7551/978-0-262-33027-5-ch036","year":"2015","citation":{"apa":"Hamann, H., Schmickl, T., &#38; Zahadat, P.

It proposes the paradigm of On-The-Fly Computing, which tackles emerging worldwide service markets. In these markets, service providers trade software, platform, and infrastructure as a service. Service requesters state requirements on services. To satisfy these requirements, the new role of brokers, who are (human) actors building service compositions on the fly, is introduced. Brokers have to specify service compositions formally and comprehensively using a domain-specific language (DSL), and to use service matching for the discovery of the constituent services available in the market. The broker's choice of the DSL and matching approaches influences her success of building compositions as distinctive properties of different service markets play a significant role. In this paper, we propose a new approach of engineering a situation-specific DSL by customizing a comprehensive, modular DSL and its matching for given service market properties. This enables the broker to create market-specific composition specifications and to perform market-specific service matching. As a result, the broker builds service compositions satisfying the requester's requirements more accurately. We evaluated the presented concepts using case studies in service markets for tourism and university management.","lang":"eng"}],"file":[{"date_updated":"2018-03-21T09:26:04Z","date_created":"2018-03-21T09:26:04Z","creator":"florida","file_size":234260,"file_name":"280-07196546.pdf","access_level":"closed","file_id":"1470","content_type":"application/pdf","success":1,"relation":"main_file"}],"status":"public","type":"conference","publication":"Proceedings of the IEEE 11th World Congress on Services (SERVICES), Visionary Track: Service Composition for the Future Internet","title":"Market-Specific Service Compositions: Specification and Matching","doi":"10.1109/SERVICES.2015.58","date_updated":"2022-01-06T06:57:49Z","author":[{"first_name":"Svetlana","last_name":"Arifulina","full_name":"Arifulina, Svetlana"},{"first_name":"Marie Christin","last_name":"Platenius","full_name":"Platenius, Marie Christin"},{"full_name":"Mohr, Felix","last_name":"Mohr","first_name":"Felix"},{"id":"107","full_name":"Engels, Gregor","last_name":"Engels","first_name":"Gregor"},{"full_name":"Schäfer, Wilhelm","last_name":"Schäfer","first_name":"Wilhelm"}],"date_created":"2017-10-17T12:41:46Z","year":"2015","citation":{"ieee":"S.
