The advent of second and third generation cellular systems forces cellular operators to face considerable increase in the signaling traffic over their mobile networks. Service providers are therefore required to h ave a ppropriate planning tools in o rder to maintain adequate service quality levels. This paper presents a proposal of a simulation architecture for analysis of signaling in GSM and...

Large-scale cyber-physical infrastructures, such as the Smart Power Grid, are envisioned as some of the core elements of the future Internet of Things. These critical infrastructures move more and more beyond centralized management and control by system operators and administrators. Overloading and failures in the Smart Power Grid threaten the matching of demand-supply especially when new emerg...

Our conceptualization of enterprise systems as symbolic systems gives rise to the study of enterprise system implementation in terms of semiotic and linguistic categories. While drawing on the...

An agent-based organizational model for a smart energy system is introduced relying on a dynamic coalition formation mechanism for virtual power plants. Central to this mechanism we propose a solution concept that stems from the existent stability notions in coalitional games. The process is intended as an open-ended organizational adaptation, concerned with achieving stable configurations that...

Organization concepts and models are increasingly being adopted for the design and specification of multi-agent systems. Agent organizations can be seen as mechanisms of social order, created to achieve common goals for more or less autonomous agents. In order to develop a theory on the relation between organizational structures, organizational actions and actions of agents performing roles in ...
