Double Guarantee for Security Localization in Wireless Sensor Network

Wireless Sensor Network security localization technologies are usually designed just for one type of attack or single step transmission for the message packets, which would be less robust in complex network environment. In this paper, we propose a novel WSN security localization algorithm: Double Guarantee Security Sensor Localization, which can enhance the reliability and security of message packets via message source authentication and suspicious data filtration, and improve the localization accuracy through applying the self-adaptively established signal attenuation model to the dynamic network environment. In the experiments, we stimulate and verify the accuracy of DGSSL algorithm under different attack conditions and achieve better performance than the compared algorithms.
