A Formal Petri Net Based Model for Antivirus Update Agent System

In this paper, a formal model for antivirus update agent system is presentedbased on mobile agent technology and predicate/transition Petri nets. The mobileagent system contains two mobile agents called DCA and UNA. It sends out agentsto update antivirus on client computers in a network. Each agent takes on aspecified responsibility. First, DCA roams through the network and check the lastdate of updating of antivirus on client computers. Then, by passing the list ofunupdated client computers to UNA, next migration is started. The mobile agentsystem is modeled with logical agent mobility method (LAM) using Petri nets. Eachagent is modeled with a predicate/transition Petri net. In this model, the antivirusupdating system consists of a set of components to identify different locations and aset of connectors to specify the interactions among the components. Connectors andcomponents are modeled with PrT Nets.
