Dynamic Localization Schemes in Malicious Sensor Networks

Free registration required

Executive Summary

Wireless Sensor Networks (WSN) have recently shown many potential military and civilian applications, especially those used in hostile environments where malicious adversaries can be present. The accuracy of location information is critical for such applications. It is impractical to have a GPS device on each sensor in WSN due to costs. Most of the existing location discovery schemes can only be used in the trusted environment. Recent research has addressed security issues in sensor network localization, but to the best of the authors' knowledge, none have completely solved the secure localization problem. In this paper, they propose novel schemes for secure dynamic localization in sensor networks.
