Attack-Resistant Location Estimation In Wireless Sensor Networks, Dongdang Liu, Peng Ning, An Liu, Cliff Wang, Wenliang Kevin Du

Electrical Engineering and Computer Science

Many sensor network applications require sensors’ locations to function correctly. Despite the recent advances, location discovery for sensor networks in hostile environments has been mostly overlooked. Most of the existing localization protocols for sensor networks are vulnerable in hostile environments. The security of location discovery can certainly be enhanced by authentication. However, the possible node compromises and the fact that location determination uses certain physical features (e.g., received signal strength) of radio signals make authentication not as effective as in traditional security applications. This paper presents two methods to tolerate malicious attacks against range-based location discovery in sensor networks ...
