We study the potential threat for virus spread in wireless sensor networks (WSNs). Using epidemic theory, we proposed a new model, called susceptible-infective-recovered with maintenance (SIR-M), to characterize the dynamics of the virus spread process from a single node to the entire network. By introducing a maintenance mechanism in the sleep mode of WSNs, the SIR-M model can improve the network's...
The paper introduces a model of wireless sensor network (WSN) nodes with SystemC-AMS, a C++ based language for system-level description, then presents model refinements and simulation improvements of the system. Firstly the paper details the components of a WSN node : a sensor, an ADC, a microcontroller and a RF transceiver with some introduced impairements. Secondly, it presents the implementation...
