Complex Mobile Multiagent Systems

Mobile agents as network computing technology has been applied to solve various parallel and distributed computing problems, including parallel processing, information search and network management. Protection of the mobile agents in the network and against the hosts is a difficult task. In this paper, we analyze the increased security solutions provided by a novel class of mobile agents called ICMA agents developed during our previous researches. An ICMA multiagent system is a complex system, composed from relatively simple agents who at the level of the system has a complex behavior. ICMA mobile agents have some advantages in the protection versus other mobile agents described in the literature. The self-protection mechanisms consist in distributing the problem solving knowledge, reducing the useless distributed problem solving knowledge in time and intelligent controlling of the distributed operating components. In this paper there are introduced the notions internal and external complexity of an agent-based complex system.
