Ph.D Thesis (Expected December 2008):

Systems Optimization in Mobility Management

 

Advisor: Professor Henning Schulzrinne, Columbia University, NY

 

This thesis proposes a systematic model to mobility management and proposes several optimization techniques that supports subnet, domain and inter-technology roaming for real-time interactive and streaming application in the wireless Internet. We analyze the common abstract properties resulting out of a mobility event, demonstrate and analyze proactive and predictive fast-handoff mechanisms that help reduce the binding delay at several layers and reduce the packet loss by means of dynamic buffering techniques.
