Performance evaluation of IDMP's QoS framework

Intra-Domain Mobility Management Protocol (IDMP) has been recently proposed as a protocol for managing IP mobility within a cellular access network. This papere valuates the performance of IDMP's Quality of Service (QoS) framework, which uses a modified form of the Differentiated Services architecture, with a centralized Bandwidth Broker performing admission control and resource provisioning for different traffic classes. While experimental results demonstrate that our IDMP-based QoS mechanism is able to support differential performance guarantees for mobile users with fairly low latency overheads, analytical derivationss how that this QoS support can be achieved with only a marginal increase in the signaling cost.
