Conclusion
We presented a new QoS-aware mobility management mechanism. The new mechanism supports both intra-domain and inter-domain mobility and it co-exists with Mobile-IP and NEMO.
Using NS2 simulations, we demonstrated that QMM is significantly superior to Mobile-IP in managing intra-domain node mobility and inter-domain node mobility when guaranteed QoS is required.
