RCACM: Role-based context-awareness coordination model for mobile agent applications

In this paper, we present an RCACM coordination model for mobile computing applications based on mobile agents. The key idea in RCACM is the role-based context-awareness hierarchical coordination model. In this model, local programmable reactive tuple space is introduced to address the context-aware coordination problems and hierarchical distributed tuples can make agents dynamically acquire information about resource location and availability according to their permissions; role mechanism is adopted for access control to prevent unauthorized access.
