Abstract
In this article we survey the latest progress on sensor localization, focusing on distance measurement techniques and localization algorithms for a sensor to determine its own location. We illustrate why inaccurate distance measurements, arising from tight hardware design constraints, raise challenges in sensor localization and how proposed approaches strive to overcome these challenges. We conclude that sensor localization algorithms must be designed to accommodate different application requirements in terms of costs, energy consumption, and localization accuracy
