Agent Behavior

In a previous work (Amara-Hachmi & El Fallah-Seghrouchni, 2004), we proposed a component-based generic adaptive mobile agent (GAMA) architecture that exhibits a minimal mobile agent behavior. In this article, we will focus on GAMAs’ awareness of their execution context. Thus, we propose a formal model of context to be used in a semantic approach for checking agents’ compatibility with new execution contexts. The remainder of this article starts with definitions of context and context-awareness for GAMA mobile agents. We then introduce our context model and detail the proposed approach, before concluding the article.

Different Sources

In the past decade, ontology has been actively researched in various domains. The different ontological tasks range from simple language modeling in the linguistic domain, to semantic integration in the semantic web, and recently to application-specific tasks such as financial fraud management. We follow the trend and attempt to tackle some of the ontological problems in security management. The most complicated problem out of all is the semantic interoperability problem that is evident in the existence of various types of security elements such as IDS, firewall and virus scanner. Another problem is related to the semantic modeling tasks required for autonomous and intelligent reasoning. Semantic modeling of security events is essential for automatic and intelligent event correlation tasks that analyze semantically the different sources of security information to more accurately present the holistic network security status. We present in this paper a novel and formal ontology mapping approach and security ontology for the supporting and possibly resolution of these problems.
