We present a study of the novel mathematical model, CISER, in this work. The proposed model is a more general variant of the SIR epidemic model for representing information spread. The work provides an analysis of the mathematical model, in particular, the inclusion of carrier and exposed states in providing a more generalized representation toward SIR. The model also provides an accurate description of the disease amoebiasis and relates the disease characteristics to message propagation. We derive various properties of importance and depict the model representation of various states of spread (message propagation) through numerical results. Based on this model, we then provide an epidemic controlled flooding mechanism for information spread in a mobile ad hoc network (MANET). This is accomplished through a reactive IPv4-based routing protocol built on top of the MAC 802.11b layer. We further present our simulated results and perform a comparative analysis against other epidemic routing protocols such as SIR and SEIR. We discover our model performing better in terms of most performance metrics.
