We focus on an open and extendable distributed robotics system, which in contrast to most existing proprietary robotics systems, supports cost-effective integration and assembly of components while providing dependable communication and coordination. To demonstrate feasibility we have developed the CERO Framework for ad hoc cooperation in robots communities employing a service-oriented architecture with the main building blocks: ad hoc networking for different wireless technologies (e.g., Bluetooth, WLAN, or 433 MHz radio communication), a protocol for interconnecting development board and actuators, and a CE.NET based software framework supporting complex movements, consensus protocols, cooperation, and positioning. It offers high-level interfaces for programming complex tasks in cooperative robotics. We also present an overview of intended applications.}, language = {en} } @article{StantchevMalek2011, author = {Stantchev, Vladimir and Malek, Miroslaw}, title = {Addressing Dependability throughout the SOA Life Cycle}, series = {IEEE Transactions on Services Computing}, volume = {4}, journal = {IEEE Transactions on Services Computing}, number = {2}, pages = {85 -- 95}, year = {2011}, abstract = {Dependability should be considered throughout the phases of the SOA life cycle. This article proposes the application of a service level management approach to address dependability and presents dependability-related activities for every stage (Model, Assemble, Deploy, and Manage) of the SOA life cycle. Furthermore, we describe the concepts and the formalisms that are behind these activities. Following these activities service providers and aggregators can offer optimized levels of dependability from their existing services and thus better meet user requirements.}, language = {en} } @incollection{IbachMalekTamm2006, author = {Ibach, Peter K. and Malek, Miroslaw and Tamm, Gerrit}, title = {Towards a Global Real-Time Enterprise}, series = {Emerging Spatial Information Systems and Applications}, booktitle = {Emerging Spatial Information Systems and Applications}, editor = {Hilton, Brian N.}, publisher = {Idea Group Publishing}, address = {Hershey}, publisher = {SRH Berlin University of Applied Sciences}, pages = {271 -- 309}, year = {2006}, abstract = {Frictionless interoperation of business processes even across enterprise boundaries, complete up-to-date view of the overall status, and full remote control over the business parameters for individuals in charge - this is the holy grail of a "global real-time enterprise". Yet a vision, a number of enabling technologies brought us closer to accomplishing the challenges: Sensing the position of mobile objects and processes status, distributing the status information with "zero latency", discovering it according to specific demands across organisation boundaries, providing and securing uniform service-oriented access to all kinds of entities ranging from smart items to business processes, and aggregating the overwhelming variety of elementary services to form high-value composite services. In this chapter, we overview the enabling technologies that drive the development and further discuss market factors, security and privacy concerns, and standardization processes that have to be considered. Then we propose our SEMALON approach - the SEMAntic LOcation Network - intended as a basic infrastructure for discovery and composition of location based services. Finally we describe our experiences from a case study implementation - the NOMADS Campus - which is a distributed spatial information system for our campus at Humboldt University Berlin.}, language = {en} }
