A cellular IP testbed demonstrator

Cellular IP is a wireless Internet access technology that operates on mobile hosts, base stations and Internet gateways. Cellular IP combines the capability of cellular networks to provide high performance handoff and efficient location management of active and idle mobile users with the inherent flexibility, robustness and scalability found in IP networks. We provide an overview of the cellular IP routing, handoff and paging algorithms and their implementation in a pico-cellular testbed. The protocol has been under development at Columbia University for the past several years initially as a joint project between the Center for Telecommunications Research and Ericsson Research.
