Performance evaluation of a framework to support path changes in IP-based access networks

ABSTRACT

The increasing use of wireless networks and the popularity of multimedia applications, leads to the need of Quality of Service support in a mobile IP-based environment. In [1], we investigated the reasons for path changes in the access network and we presented a framework to support these path changes regardless their cause and to avoid router inconsistencies. In this paper, the performance of this framework is thoroughly evaluated. To this end, we added the functionality of the framework to our Q-MEHROM handoff scheme [2]. However, the ideas and results presented in this paper are not restricted to this micromobility protocol. The performance with and without the defined functionalities is compared and tested under different network topologies, in terms of received service, packet loss and end-to-end delay.
