1. Problem in Current Internet - Supporting Seamless Connection in Heterogeneous Networks Future Internet term project KHU Computer Engineering Networking Lab Rim Haw 2008. 09. 29

2. Figure 1. The devices support wireless Internet nThe rapid improvement of devices such as a cellular phone or mp3 player. nDesires of using internet in the outdoor. nToday many devices is added a Wireless Internet function. In the future, it is basic function to use wireless internet in any devices. Introduction

3. What is the Problem ? nWhat is the problem in current internet? – low power, speed, connection, QoS, etc. - Seamless Connection : Now it’s necessary to connect access points for using internet. Then People who want to use the Internet find another access points. One device is adapted one network. Because Current internet is based by TCP/IP which did not consider wireless environments - Mechanisms is needed to connect between different networks like SHIM6 X X Figure 2. Problem in current internet Figure 3. Architecture of SHIM6

4. Conclusion nIn the future, anywhere and at any time people using their devices can confirm their e-mail, enjoy movie streaming and communicate others’ devices using wireless internet. nCurrent Internet is inconvenient to keep connection seamless and is necessary to support connections among heterogeneous networks, then I try to solve seamless mobility problem in this class
