Abstract
Abstract In order to cope with the heterogeneity, autonomy and diversity of interests among the different agents in open multi-agent systems, several governance mechanisms have been defined. Governance mechanism enforce the behavior of agents by establishing a set of norms that describe actions that agents are prohibited, permitted or obligated to do. In this paper we present a governance mechanism that enforces not only dialogical actions but also non-dialogical ones. Although several governance mechanisms have been proposed, none of them satisfactorily deals with non-dialogical actions. Our proposed mechanism is based on testimonies provided by agents about the behavior of other agents. The governance mechanism provides decisions pointing out if norms have been violated or if false testimonies have been supplied. The decisions are based not only on testimonies and depositions provided by the agents but also on the agents’ reputations supplied by a reputation system that is part of the mechanism.
Highlights
Open multi-agent systems are societies in which autonomous, heterogeneous and independently designed entities can work towards similar or different ends [13]
In this paper we propose a governance mechanism based on testimonies provided by witnesses about facts or events that they know are related to norm violations
Such an approach may provide support for the automation of the negotiation between the agents looking for reducing the prices and the delivery time. Such applications are particular governed by several rules that are used to regulate the behavior of the heterogeneous and independently designed entities that reinforce the open characteristic of the systems. Since such rules are adequately modeled as norms in governance multi-agent systems, this paper focuses on presenting a governance system for regulate norms that are related to the interactions between the agents and to actions that can modify the application environment
Summary
Open multi-agent systems are societies in which autonomous, heterogeneous and independently designed entities can work towards similar or different ends [13]. In this paper we propose a governance mechanism based on testimonies provided by witnesses about facts or events that they know are related to norm violations. In [5] the authors propose an access control mechanism to handle the access to resources Such governance is restricted and only applied to resources that are inserted in tuple centre environments; and (iii) Other approaches such as [20] claim that the governance system enforces only the observable behavior of agents in terms of public messages and visible actions.
