Dynamic Behavior of SIR Epidemic Model with Immunity on Complex Networks

This paper studies the dynamic behavior of SIR epidemic model with immunity on complex networks.First,effects of immunization on the spread of epidemic on homogenous networks in which the node degrees obey an exponential distribution are considered.The effects of immunization and the quality of heterogeneous on the spread of epidemic in heterogeneous networks,in which the node degrees satisfy a power-law distribution rather than the exponential distribution,are then discussed.
