Using Random Walk to Protect Source-location Privacy in Wireless Sensor Networks
Zhao Ze-mao · Journal of Hangzhou Dianzi University · 2012
One of the looming challenges that threaten the successful deployment of wireless sensor networks is source-location privacy.In order to enhance source location privacy in sensor networks,this paper proposes a new scheme called NDRW.In NDRW,a non-repetitive strategy is introduced,and packets are forwarded to the sink node through non-repetitive directed random walk.Simulation results show that NDRW can increase the safety period and provide a strong source-location privacy protection.Finally,some problems needed to study further are pointed out.
