A trusted measurement scheme for wireless sensor networks

Abstract

The information technology has made wireless sensor widely used. But however, the security problem of wireless sensor network becomes more and more serious. Due to limited resource, the security mechanism of traditional network can't be applied to wireless sensor network. This paper proposes a trusted measurement scheme to ensure wireless sensor network running well and securely. This scheme is based on static measurement and combines active measurement with passive measurement. The real-time measurement is the running security assurance for wireless sensor network. It can still run normally under the network security attack. The simulation proves that this scheme can ensure the wireless sensor network running well and has little effect on the network life cycle.
