The achievement of common objectives in multi-agent systems is only possible through interaction and coordination; in order to implement both aspects in a effective manner, rules to direct the behavior of a group of agents are necessary, however, existing rules are usually static, inflexible, and inappropriate for large systems, where dynamic interaction takes place. We propose modeling agent behavior...
Given the dynamic interaction presented in multiagent systems, the occurrence of exceptions in interaction protocols is frequent, and therefore a critical issue. However, current approaches for designing interaction protocols lack semantics to direct the exchange of messages, when exceptions are raised. Here, we propose modeling exception handlers by means of obligations, which are social norms that...
We deal with composition of semantic web services to which access is controlled by agents. We propose a conversation-based web service composition method. We conceive web services as actions with preconditions and effects, expressed in terms of social norms, particularly obligations. We argue that the inclusion of obligation-based agents' conversations aide to lead the composition of services. In...
This paper presents a cluster-based self-organizing algorithm for creating automatically ad-hoc networks including diverse wireless devices such as PDA, cell phones, laptops, wireless sensors, etc. In the proposed strategy each mobile device is represented by a multi-role agent, which generates a backbone among the devices within the environment based only on local interactions. During the operation...
Collaboration among independent systems to achieve a common objective, which a system alone could not accomplish by itself, requires dynamic composition of the participant systems, in addition to mechanisms for leading the interaction of the resultant system of systems. Here is proposed to model system of systems using a multi-agent system approach, where agents represent stakeholders of the systems...
This paper presents a method for establishing and maintaining structured formations of mobile agents in a 3D environment using self-organization strategies. In the proposed approach the position of the agents in the formation is not defined a priori and the agents are joined progressively into the structure when they arrive. Agent placement and formation balance are achieved through local interactions...
