“…This concept is first time introduced in the market as a standard by NIST. This standard is not applicable in every scenario and situation, so it has been extended by many researchers [5,9,10,12,14]. The RBAC model is very useful in large scale authorization, widely used in many organizations.…”

Abstract-Collaborative environments need access control to data and resources to increase working cooperation efficiently yet effectively. Several approaches are proposed and multiple access control models are recommended in this domain. In this paper, four Role-Based Access Control (RBAC) based collaborative models are selected for analysis and comparison. The standard RBAC model, Team-based Access Control (TMAC) model, Privacy-aware Role-Based Access Control (P-RBAC) model and Dynamic Sharing and Privacy-aware RBAC (DySP-RBAC) model are used for experiments. A prototype is developed for each of these models and pros and cons of these models are discussed. Performance and sharing parameters are used to compare these collaborative models. The standard RBAC model is found better by having a quick response time for queries as compared to other RBAC models. The DySP-RBAC model outperforms other models by providing enhanced sharing capabilities.

“…Moreover, roles allow the uncoupling of the features of the individuals from those of their roles. Finally, roles are used to define common interaction patterns, and embed information and capabilities needed to communication and coordination [11]. E.g., the roles of auctioneer and bidder are defined in an auction, each with their possible moves.…”

Abstract. Social roles structure social institutions like organizations in MultiAgent Systems (MAS). In this paper we describe how to introduce the notion of social role in programming languages. To avoid the commitment to a particular agent model, architecture or language, we decided to extend Java, the most prominent object oriented programming language, by adding social roles. The obtained language allows an easier implementation of MAS's w.r.t. the Java language. We also show that many important properties of social roles, studied in the MAS field, can be applied to objects. Two are the essential features of social roles according to an analysis reported in the paper: social roles are defined by other entities (called institutions), and when an agent plays a role it is endowed with powers by the institution that defines it. We interpret these two features into the object oriented paradigm as the fact that social roles are objects, which are defined in and exist only inside other objects (corresponding to institutions), and that, through a role, external objects playing the role can access to the object (institution) the role belongs to.

“…Modern coordination mechanisms mainly rely on non-central control schema, including distributed blackboard [CL00], contracting for coordination [S80 and FI02], social laws [ST95 and FT00], and role-based approaches [CF04]. As an extension of the traditional blackboard, Tuple-Spaces [CL00] contain a set of tuples, which hold information relevant for the application.…”

-One approach to modeling multi-agent systems (MAS) is to employ a method that defines components which describe the local behavior of individual agents, as well as a special component, called a coordinator. The coordinator component coordinates the resource-sharing behavior among the agents. The agent models define a set of local plans, and the combination of local plans and a coordinator defines a system's global plan. Although earlier work has provided the base functionality needed to synthesize inter-agent resource sharing behavior for a global, conflict-free MAS environment, the lack of coordination flexibility limits the modeling capability at both the local plan level and the global plan level. In this paper, we describe a flexible design method that supports a range of coordinator components. The method defines four levels of coordination and an associated four-step coordinator generation process, which allows for the design of coordinators with increasing capabilities for handling complexity associated with resource coordination. Colored Petri Net-based simulation is used to analyze various properties that derive from different coordinators and synthesis of a reduced coordinator component is discussed for cases that involve homogeneous agents.
