Micromobility protocols performance in differentiated services networks

This work analyses and compares the performance of the recently proposed micro-mobility protocols HAWAII and Hierarchical MIP when submitted to several levels of traffic load and scenarios that effectively degrade the low packet loss feature of these protocols. Furthermore, it is shown that the use of differentiated services within a given domain infrastructure results in a considerable increase of performance for mobile nodes. The preferential treatment offered to such mobile nodes protects micro-mobility protocols traffic from the fluctuations of background traffic with losses only occurring as a result of handoff events.
