Epidemic spreading in wireless sensor networks (WSNs) has lately attracted the attention of many researchers as a hot problem in nonlinear systems. Using wireless connectivity, the sensor nodes that makeup WSNs are linked to one another in a decentralized and distributed structure. Decentralized architectures and resource limitations pose a security risk for WSNs. Malware attacks the WSN’s sensor nodes, paralyzing them while collecting data from the network. Attacks by malware can increase the energy use of WSN sensor nodes. It just began spreading from one infected node and uses nearby nodes to expand over the whole WSN. Therefore, the protection of WSNs against malware attacks is a need that cannot be avoided. In this research paper, we propose an epidemic model to discuss the impact of charging on sensor nodes, coverage, and connectivity, considering prior research. The suggested model …
