Simulating the Spread of a Virus in a Computer Network
In this paper we propose a simulation problem that can be used as an exercise in a simulation class using an excel add-on simulation package. Suppose that N objects computers, people, animals, plants are interacting in pairs. Every time unit for example, a second for a computer, a day or a week for people, each object randomly selects another object and contacts it. Suppose that one object is infected with a virus. How long will it take until all objects are infected? How many objects are infected after 5 time units? This process is a simplified model for the spread of AIDS among humans, computer viruses among computers, or any communicable disease among humans, animals, or plants.
