Mobile computing for personal communication system (PCS) that offers mobile users anytime, anywhere, bi-directional reliable access to the Internet. Mobile IP as a network layer protocol provides solution to requirements of mobile computing. Due to terminal mobility and change of service area, efficient mobile IP support is an important issue in heterogeneous network in order to minimize packet loss and Hand off latency to the mobile users. In our project we have proposed a loosely coupled UMTS/WLAN integration architecture with mobile IP as a service continuity solution. We have used generic routing encapsulation as a tunneling protocol between these two dissimilar networks. After designing the architecture we created a simulation model using OPNET 14 as a simulation tool. Through simulation we have analyzed the performance of the proposed architecture.
