Secure Localization and Location Verification of Wireless Sensor Network

Sensor nodes´ locations perform a vital role in many sensor network applications. Localization of sensor node in Wireless Sensor Networks adds security issues such as node re-authentication and tracing the movement. A number of techniques have been proposed recently to solve the locations issues of regular sensors but inadequate to support hostile and dynamic environments since their designs are only for the static environments. In this paper, we propose the well-organized node authentication and key exchange protocol that trim downs the overhead in node re-authentication and also facilitates untraceability of localized nodes. The proposed protocol will be the efficient solution to increase the lifetime of sensor network.
