Our approach is called HMIPv6-BI. It proposes a modification to the Hierarchical Mobile IPv6 protocol. The goal of HMIPv6-BI is to minimize the Bandwidth usage in the Radio Link between Access Router(AR) and the Mobile Node (MN). Currently, in HMIPv6 a tunnel is established between the Mobility Anchor Point (MAP) and the MN. On the other hand, the principle used by HMIPv6-BI is to move the Tunnel End Point until the AR. In consequence, this aspect decreases the number of bytes traveling over the wireless interface due to the absence of the tunnel headers required in the original approach. Furthermore, HMIPv6-BI allows the usage of Multicast Tunnel (this approach is named TMCast+HMIPv6-BI) in order to reduce theHandover Latency. Finally, modeling and simulation results indicate that HMIPv6-BI provides better performance as compared to the standard approach*. *This work was supported by the ERDF and the Spanish Government through the TIC2006-04504 project.
