The heterogeneous interface for the mobile node is the key feature for the next generation mobile world. It provides the flexibility for the mobile devices for moving devices to the next available best network for high data rate connection. So, it is firstly important to develop in ns2 for the research and educational purposes. It is very important to develop it in ns2 so that the authors can do experiment on the heterogeneous interface. The heterogeneous interface provides the mobility to the networks that is the people can connect to any best available network like WIFI/WIMAX/UMTS for fast data connection. In this paper, they will discuss about the various methods of implementation for heterogeneous interface of mobile node in ns2.
