Abstract

A “Crossover Router” (CR) based QoS provisioning mechanism under an enhanced “Fast Handovers for Mobile IPv6” (FMIPv6) architecture has been proposed to provide better performance for multimedia applications in Mobile IPv6 (MIPv6) networks. In the proposal we extend the FBU and HI messages to notify the QoS requirement of “Mobile Node” (MN). Advance reservations along the possible future-forwarding paths are performed only between CR and MN to reduce reservation hops and signaling delays. In this paper we present the detailed performance evaluation results of this scheme compared with “Mobile RSVP” (MRSVP) protocol, using the network simulator (NS-2). In the simulations RSVP signaling cost, total bandwidth requirements, RSVP signaling and data packet delay in different scenarios of both schemes were considered. Results show that the proposed scheme for QoS guarantee has lower RSVP signaling cost and delay, as well as less bandwidth requirements in comparison with MRSVP. Furthermore, fluctuation and peak values of data packet delays in different scenarios are much lower.
