Context Awareness in mobile software agent network

The paper deals with context awareness in information, communication and computing systems and context introduction in mobile software agent network. Mobile agent network is a formal system that includes a multi-agent system residing in a network of interconnected nodes, which hosts agents, allowing their operation, communication and migration. Software agents can help in managing complex relationships between information and communication service users and service providers. The role of intelligent and mobile agents representing service users and service providers in the network and supporting context awareness is considered. Context is defined as any information that can be used to characterize the situation of an entity respecting its physical, social, communication and computing environment. A unified treatment of context information contained in the user profile, presence service and those relevant for general context-aware systems is proposed in order to preserve the functionality and performance evaluation capabilities of the mobile agent network. The approach elaborated in the paper is based on conceptual context representation, system services and agent operations required for supporting context-awareness in the mobile agent network. Case study on agent-based ad-hoc social network service is included.
