This project presents an extension to ns-2, which enables a normal user, who has basic knowledge of ns-2, to simulate localization system within a wireless network. Moreover, this project would be beneficial to researchers who want to implement new or existing localisation algorithms and anyone new to ns-2 who wish to know more about how a simulation project is built and structured. , provide more details.
