Abstract
Vertical handovers (VHO) are expected to be a key feature in
Beyond 3G (B3G) networks. This paper presents a Pastry-based P2P
overlay network for supporting vertical handover in B3G networks.
The P2P overlay is used to quickly locate attachment points (APs)
for mobile entities and to rapidly retrieve the configuration and
coverage information of these APs. The advantage of the P2P-based
solution is its distributed nature, its scalability, and its
self-organizing capability.
