Abstract

In Mobile IPv6 (MIPv6), the handover process reveals numerous problems manifested by timeconsuming network layer-based movement detection, non-optimized time sequencing of handover procedures and latency in configuring a new care of address with duplicate address detection (DAD). The delays associated with DAD and movement detection are unavoidable in MIPv6. To mitigate such effects we specify a more efficient fast Neighbor Discovery and DAD scheme. This approach requires each access point to execute movement detection by unicast transmission of the Stored Router Advertisement message and implementation of a modified Neighbor Cache to handle care of address configuration with fast DAD. Simulation results show that the proposed scheme can yield better performance than the Mobile IPv6, Fast Mobile IPv6 and Fast - Hierarchical Mobile IPv6.
