A Context-Aware Multi-Agent Systems Architecture for Adaptation of Autonomic Systems [chapter]

Kaiyu Wan, Vasu Alagar
2012 IFIP Advances in Information and Communication Technology  
In this paper we provide an insight into these issues and propose a multi-agent system that interact faithfully among themselves in order to self adapt with safety and security.  ...  In order to fulfill this requirement autonomic systems must have awareness abilities, context gathering mechanisms, context-dependent adaptation policies, and the ability to react with respect to each  ...  Both types of rules are usually applicable in many different contexts. Context information is both heterogeneous and multi-dimensional.  ...

Introductory Chapter: Multi-Agent Systems [chapter]

Jorge Rocha, Inês Boavida-Portugal, Eduardo Gomes
2017 Multi-agent Systems  
Most authors agree that although there are multiple definitions of the term 'agent', several attributes can be pointed out such as heterogeneity, autonomy, capacity to process and  ...  For dynamic and not fully accessible environments, the agents must be able to react to changes in the environment and reason if the original objectives are still valid, due to the changes in the environment  ...  It can also be called a multi-agent system (MAS) or agent-based system (ABS). In a computer science (e.g.  ...

Context adaptative systems based on horizontal architecture for ubiquitous computing

Nicolas Ferry, Stéphane Lavirotte, Jean-Yves Tigli, Gaëtan Rey, Michel Riveill
2009 Proceedings of the 6th International Conference on Mobile Technology, Application & Systems - Mobility '09  
Then, using this approach we will be able to build contextadaptative systems that interact directly with their environment. Finally we will evaluate our approach in term of reactivity.  ...  However, after having shown some limitations of AAs in the field of context-awareness we will introduce a way to improve them using a multi-cycle weaving approach.  ...  AAs allow us to adapt a component based system to its environment where adaptation is a dynamic reactive composition. But there were some lacks in the field of context-awareness.  ...

New Approach Timer for the Control of the Distributed Systems with the MultiAgents Systems

Saqalli Meryem, Medromi Hicham
2011 International Journal of Computer Applications  
The real-time systems concern IT applications having a role of follow-up or control of process in an environment which evolves dynamically.  ...  The objective of this Timer approach is to verify the capacity of every agent to perceive its environment and to elaborate an answer in the required time.  ...  Actually, numerous examples of use of the multi-agents systems in a context time -reality advance more the distributed aspect than the aspects of decentralization and autonomy.  ...

Low Power Operating System for Heterogeneous Wireless Communication System [chapter]

Suet-Fei Li, Roy Sutton, Jan Rabaey
2003 Compilers and Operating Systems for Low Power  
Operating systems in embedded wireless communication increasingly must satisfy a tight set of constraints, such as power and real time performance, on heterogeneous software and hardware architectures.  ...  More efficient solutions are obtained with OS's that are developed to exploit the reactive event-driven nature of the domain and have built-in aggressive power management.  ...  In the following sections, we will elaborate on the roles of the "system level OS" in the context of PicoRadio III, a next generation heterogeneous wireless communication system and discuss the necessary  ...

Multi-agent Designs for Ambient Systems

Kendall E. Nygard, Dianxiang Xu, Jonathan Pikalek, Martin Lundell
2008 Proceedings of the First International Conference on Ambient Media and Systems  
Because ambient systems have unpredictable requirements and are context-aware, software designs must support dynamic and sustainable change.  ...  Features of an aspect-oriented, multi-agent, architectural description language are presented as a mechanism for reasoning about cross-cutting concerns.  ...  Such an environment involves the participation of heterogeneous devices, forming an open, dynamic system, where the available resources, context and activities change continuously.  ...
