A Fast Handover System Evaluation in an All-IPv6 Mobility Management - Wireless Broadband Access based Hotspot Network Environment

摘要

The ongoing convergence of wireless networking and IP networking more and more requires solutions for transporting realtime application data to IP enabled mobile devices and mobile networks. Even though the basic Mobile IPv6 protocol suite performs sufficient in macro environments with non realtime traffic, seamless mobility requires some more enhanced protocol procedures in between the mobile node and the involved network entities.Limiting the effect of handovers has the potential to considerably improve handover performance in terms of latency, packet loss, signaling overhead, and scalability. This contribution is going to present an extensive simulation study on the performance of the Fast Handovers for Mobile IPv6 approach. The demonstrated simulation scenario comprises 9 access router and up to 70 Mobile Nodes that communicate in accordance with the popular IEEE 802.11 wireless LAN standard.
