Abstract

One of the important factors for Mobile IP version 6 (MIPv6) is to ensure a seamless handover while a Mobile Node (MN) maintain active communication. A seamless handover can be realized by reducing or finishing the latency times during movement detection, a new address configuration and binding update procedures which have been defined in MIPv6 protocol clearly. However, MIPv6 handover process is a very complex due to Layer 2 (L2) and Layer 3 (L3) operations, and this drawback can cause significant performance degradation in macro mobility or real-time communications mainly. L3 handover is the most important factor to MIPv6 handover process because a major proportion of the total handover latency occurs in this stage. On the other hand, L2 handover results in the less latency than L3 handover. However, the researches on L2 handover also has an important place in literature because the events during L2 handover can trigger L3 handover in advance. By this way, seamless handover techniques have been realized. L2 approach is faster than L3 based solutions. Nevertheless, these methods are also limited to L2 handover latency. In this paper, we analyzed the L2 latency in MIPv6 handover using OMNeT++ simulator. These analyses will show the each components of the L2 handover latency separately.
