Abstract
In wireless sensor networks,sensors should have some mechanisms to learn their locations since sensed data without associated location information may be meaningless. While many sensor localization algorithms have been proposed,security issues in sensor localization are usually not adressed in their original design. Secure sensor localization is very challenging due to limited computation and energy resources in sensors. It is highly desirable that a localization scheme in robust and is able to detect malicious attacks without using complex cryptographic operations. In this paper , we present and analyze detection methods purley based on geometric constraints in sensor networks. Our detection methods can strengthen the localization algorithm to be resilient to malicious attacks by detecting and eliminating the negative impact of fake information.
