IP Mobility and Its Impact on Satellite Networking

With the advent of new generation of wireless networks (3G and beyond) and the convergence of network technologies and services around IP, mobility is about to be a common feature integrated in all future networks. In GEO satellite networking, the deployment of Mobile IP raises some important issues that need to be addressed. This paper aims to pinpoint the impact of mobility in a satellite system with other key network features - namely QoS, multicast, and the specific issue of TCP acceleration with PEPs. Some candidate solutions based on the Mobile IP v6 framework and extensions are proposed and analyzed.
