Location-based Security Authentication Mechanism for Ad hoc Network

Abstract—With the growing prevalence of wireless networks, location information plays a critical role in many applications. Especially, in unattended and hostile environment, whether the location of a node lies on a security area became very important. In this paper, we first analyze the security and vulnerability of existing distance estimation techniques. Then utilizing some distance estimation methods, we show a Round-Trip Distance Estimation Algorithm by Verifier Recording Time. Due to its property resisting distance reduction attacks, we provide a location-based security authentication mechanism in ad hoc network. In addition, we show the advantages of our method resisting some common attacks. Keywords- Ad hoc networks; location; secure access; distance estimation I
