Abstract :
Energy efficiency, scalability and robustness are key features of Ad-hoc and Wireless Sensor Networks and the use of decentralized algorithms is of practical importance in such scenarios. A method for node localization is proposed by solving a nonlinear least-squares problem in a distributed fashion. For that purpose we propose a Gauss-Newton algorithm with embedded consensus that requires only local communication and converges to the centralized version.
