Mathematical Modelling, Analysis Involving Behaviour of Infectious Nodes in a Computer Network

This article proposes a model based on biological epidemic model in order to comprehend the behaviours of infectious codes in a computer network. Further, we establish the local and global stability of the model at their equilibrium points and find the threshold parameter R0 which gives the idea about epidemic character, i.e. all the infected nodes die out, if R0< 1 and therefore the malicious codes get extinct, whereas R0> 1 implies that the infected nodes have the potential to transmit harmful codes in a network. For the purpose of accessing the spread of malicious codes in computer network MATLAB tools are used for solving and simulating the model.
