Optimization-based Secure Multi-hop Localization in Wireless Ad Hoc Networks

Sander Wozniak, Tobias Gerlach & Guenter Schaefer
The problem of localizing nodes without GPS based on a small fraction of anchor nodes which are aware of their positions is considered to be an important service for applications in wireless ad hoc networks. With an adversary trying to mislead nodes about their estimated locations, several approaches aiming to defeat attackers by means of robustness instead of cryptographic measures have been proposed in the past. Nevertheless, these robust techniques focus on single-hop based localization....
