We de�ne a simple model for studying a special type of disease that one of the two infected people will die after coming into contact with eachother. Naturally, if two people are separated by a large distance, the chances that they come into contact is smaller than if they are closer, and the probability of a disease being transferred from one to the other is also smaller. It means we have a network with preferential merging. We will see that this network is a scale-free with exponent equal to 1.5.
