Secure Verification of Location for Wireless Sensor Network

Provided by: IJCSIET Topic: Enterprise Software Format: PDF
The knowledge of sensors' locations is crucial information for many applications in Wireless Sensor Networks (WSNs). When sensor nodes are deployed in hostile environments, the localization schemes are vulnerable to various attacks, e.g., wormhole attack, pollution attack, ranges enlargement/reduction attack, etc. Therefore, sensors' locations are not trustworthy and need to be verified before they can be used by location-based applications. Here, the authors propose a lightweight location verification system that performs both "On-spot" and "In-region" location verifications.
