Abstract |
This paper proposes the new authorizing binding mechanism to reduce the binding latency between the mobile node and the correspondent node during Mobile IPv6 handover procedure. The tradeoff between security and QoS during Mobile IPv6 handover procedure is discussed. In the proposed mechanism, the authorizing binding is performed before actual handover for candidate networks where the mobile node can be attached newly, which can reduce the binding latency and thus enhance throughput degradation caused by the bidirectional tunneling. For the new authorizing binding mechanism, the return routability procedure and binding update/ack procedure are defined newly with parameters specified by information on candidate networks. In addition, cryptographic functions of authentication and encryption are also defined newly. Via experiments, it will be shown that the proposed mechanism outperforms the existing ones in terms of the L3 handover latency. |
