A novel local-centric mobility system

Abstract

Efficient, fast and seamless mobility are key requirements for the ubiquitous access of mobile nodes in 4G networks. This paper presents a network architecture extension for IPv6 mobility scenarios able to provide fast and seamless handovers between intra and inter-domain networks. Our proposal follows a local-centric mobility architecture capable of reducing the handover times and packet losses, and also minimize the global mobility signaling in 4G scenarios. This paper shows some protocol details and describes how this method can significantly increase the network performance in IP mobility scenarios. Finally, test results obtained from a prototype test-bed are presented, showing negligible packet loss and handover timings. © 2008 Springer Berlin Heidelberg.
