Combined Approach for Handover Support in MIPv6

In the future generation networks mobile IP is one of the dominating protocols that provide seamless mobility support in the internet. Although Internet Engineering Task Force has standardized various mobility management protocols like MIPv6, FMIPv6, HMIPv6, FHMIPv6 but still there is space for enhancing their performance. MIPv6 suffers from drawback like handover latency & high signaling cost. On the other hand, FMIPv6 aims to reduce handover latency but increases the extra signaling between new Access Router and previous Access Router thereby increasing the cost of the network. To tackle the issue of signaling cost, HMIPv6 introduces a mobility anchor point which aims at reducing the signaling cost but thereby compromising the other factor of handover latency. In this paper, an effective combination of both FMIPv6 & HMIPv6 i.e. FHMIPv6 has been proposed for optimization of signaling cost as well as handover latency. Also an intelligent mobility support scheme is introduced for selection of best MAP according to changing user’s mobility .This scheme also makes a selection between MIPv6 & HMIPv6. By MATLAB simulation it is shown that FHMIPv6 gives overall best results in terms of cost function among the existing host based mobility protocols.
