Development of wireless and mobile networks is towards all-IP networks, where Mobile IP is seen as de-facto global standard for handling macro-mobility. One may assume that near soon in all-IP scenario all wireless networks will be using Mobile IP. However, this increases the importance of proper implementation of Mobile IP in NS-2 as the most-used simulation environment in the scientific community. Mobile IP protocol is a possible solution that makes Internet available to mobile devices. Mobile IP is located at network layer in OSI model, and is designed as upgrade to existing network layer used in regular IP communication.
