Abstract
In this paper, we propose a fractional SIRS model with homogenous networks. The disease-free equilibrium point E0 is locally and globally asymptotically stable for R0<1 (the disease always disappears), and endemic equilibrium point E1 is uniquely locally and globally asymptotically stable, but E0 is unstable for R0>1 (the disease is uniformly persistent). The main results are demonstrated by numerical simulation.
