The Survivability Analysis Method of Wireless Sensor Network Based on SPN

摘要

This paper presents the survivability analysis modeling method of Wireless Sensor Network (WSN) based on Stochastic Petri Net (SPN). First, the survivability definition of WSN is put forward, and the data transfer model of WSN is constructed. Second, this paper describes the SPN modeling method of some security events. Lastly, simulation experiment proves the correctness and effectiveness of the modeling of WSN survivability analysis based on SPN. This model can provide theoretical basis and guide for designing a survivable WSN.
