Runtime Adaptation of Multiagent Systems for Ubiquitous Environments

There is a growing need to develop adaptive mobile agent systems to meet the increasing complexity and dynamic environments of distributed applications. This paper proposes and argues that using compositional adaptation of individual and teamed software agents allows multiagent systems to radically change their behaviors and structure at runtime. We describe and analyze an application scenario which motivates a compositionally adaptive agent based approach. The challenges and different solutions are described. The paper then proposes the VERSAG approach which is used to combine the benefits of the various approaches in a novel manner. This paper also presents experimental evaluations which compare these adaptive mobile agents with standard non-adaptive mobile agents.
