A Study of Malware Propagation Dynamics in Wireless Sensor Network Using Spatially Correlated Security Model

Background: The paper discussed about the malware propagation dynamics in wireless sensor network. Malware attack is harmful for network stability as well as battery consumption of sensor nodes. Objective: The objective of proposed study is to develop a model that describes the dynamic propagation behavior of malware in wireless sensor network and suggest corrective measure through which breakout from the network. Methods: Use the concept of epidemic modeling and spatial correlation to describe the malware dynamics in wireless sensor network. Write the sets of differential equation to study its behavior. Results: Methodically find results have been verified with the help of simulation using MATLAB. The effect of spatial correlation on malware propagation in wireless sensor network has been analyzed. Conclusion: In this paper, an epidemic based model with spatial correlation is presented for the study of malware propagation characteristics in WSN. The equilibrium points of the system have been obtained. The expression of basic reproduction number and threshold value of correlation coefficient have been obtained. The basics reproduction (R 0 ) helps in the analysis of network stability. On the basis of their value we found that if R 0 is less than one the system will be stable and malware-free, and when R 0 is greater than one the system exists in endemic state and malware persists in the network. The spatial correlation helps to control the malware propagation in the network.
