Abstract:Today’s communication networks are evolving towards an all-IP architecture. IP-level mobility protocols will have to support seamless handovers from one access technology to another. Existing IP-level mobility protocols have difficulties meeting these stringent handover delay requirements. Also, they do not give sufficient control to the network to optimize the handover process and they do not deal well with slow connection setups of some wireless technologies. This thesis presents a networked controlled IP-level mobility protocol called Simultaneous Binding Proxy Mobile IPv6 (SPMIPv6), based on the existing Proxy Mobile IPv6 protocol. The protocol deals with large layer 2 setup times by taking a proactive approach towards the handover. It is allows some parts of the handover process to be carried out before the actual handover. In the networks itself, packets for the MN are already sent to the MN’s new point of attachment before the actual handover. This way, the handover latency can be limited to one RTT between the mobile node and the new access router and the packet loss due to handover can be decreased and eliminated by appropriately buffering packets at the new access router. The SPMIPv6 protocol was implemented in testbed, which showed that both UDP and TCP do not suffer from any performance degradation during the actual handover. Two important characteristics of SPMIPv6 are its robustness to incorrect handover predictions and its built-in features to accommodate large network attachment latencies.
