Network layer handoff delay analysis for hierarchical mobile IP;

Network layer handoff delay analysis of mobility protocols;

According to the model,the handoff delay in the case of overlap is calculated and the effect of the overlap size on handoff performance is obtained.

It brings long handover delay and especially it is not available for some real-time traffic.

Based on the analyses of hierarchical mobile ipv6 mechanism,it is known that this scheme has been improved in micro handover,but has no change in macro handover in handover delay and packet loss rate.

With mobile IPv6,a mobile node can roam in different networks neither disconnecting the communication with correspondent nodes, nor changing its IP address, but the handover delay is obviously increased when a mobile node is far away from its home agent.

The thought and mothed of time-delay conversion are presented.

Two well-known approaches to reducing the MIP handoff latency are proposed,the fist is to reduce home network registration time through a hierarchical management structure,the second tries to minimize the lengthy address delay by address pre-configuration,thus realizing the fast-handoff mechanism.
