ABSTRACT
Vertical Handoff (VHO) is a major concern for different heterogeneous networks. VHO can be user requested or based on some criteria already designed by the researcher of that particular algorithm. It's about switching from one network to another while maintaining the session. Numerous algorithms have been given in this respect. In this paper a new implementable procedure has been introduced. It's a mechanism, in which multiple users having access to different networks can execute the VHO, in such a manner that when the handoff takes place it do not interrupt any ongoing call or data session. A server and clients have been created. A call was established and it was maintained by Session Initiation Protocol during switching from one network to another. By employing a technique called IP Assignment VHO was carried out successfully. The proposed scenario has made implementation of VHO practically possible.
