Q-MEHROM: Mobility Support and Resource Reservations for Mobile Hosts in IP Access Networks

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. This paper presents Q-MEHROM, which is the close coupling between the micromobility protocol MEHROM and a resource reservation mechanism. In case of handoff, Q-MEHROM updates the routing information and allocates the resources for receiving mobile hosts simultaneously. Invalid routing information and reservations along the old path are explicitly deleted. Resource reservations along the part of the old path that overlaps with the new path are reused. Q-MEHROM uses information calculated by QOSPF. Simulation results show that the control load is limited, mainly QOSPF traffic and influenced by the handoff rate in the network. Q-MEHROM uses mesh links and extra uplinks, present to increase the link failure robustness, to reduce handoff packet loss and improve the performance for highly asymmetric network loads.
