The ns-2 network simulator is one of the most widely used tools by researchers to investigate the characteristics of wireless sensor networks. Academic papers focus on results and rarely include details of how ns-2 simulations are implemented, and if published the modules tend to be scheme specific. The availability of generic and reusable modules for ns-2, which supports specific research areas while allowing great scope for customization, are limited. Researchers new to ns-2 are therefore often required to build simulations largely from first principles. This paper presents an extension to the current version of ns-2, which enables a normal user, who has basic knowledge of ns-2, to implement and simulate any custom localization system within a wireless network. The technical content of this paper would be beneficial to researchers who want to implement new or existing localization algorithms and anyone new to ns-2 who wish to know more about how a simulation project is built and structured.
