| Abstract: | In this paper, we study the dynamical behaviour of an epidemic on
complex networks with population mobility. In our model, the number
of people on each node is unrestricted as the nodes of the network
are considered as cities, communities, and so on. Because people can
travel between different cities, we study the effect of a population's
mobility on the epidemic spreading. In view of the population's
mobility, we suppose that the susceptible individual can be infected
by an infected individual in the same city or other connected
cities. Simulations are presented to verify our analysis. |
