QoS provisioning to mobile Internet users

Proceedings of the 3rd ACM Workshop on QoS and Security for Wireless and Mobile Networks

2007

To achieve smooth delivery of real-time traffic in heterogeneous mobile networks, QoS-aware MIPv6 handoff is desirable. Considering that different QoS models may be applied in the traffic path, our previously-proposed QoS Agentassisted MIPv6 handoff provides a flexible and efficient solution to this diversity. This paper presents performance evaluation results for two schemes of QoS-aware MIPv6 handoff: the simple integration of MIPv6 and QoS schemes and our QoS Agent-assisted scheme. Simulation results show that the QoS Agent-assisted scheme is able to minimize the QoS configuration latency during handoff, and it simultaneously supports multiple QoS schemes.

Performance evaluation of qos-agent assisted mipv6 handoff scheme

Proceedings of the 3rd ACM Workshop on QoS and Security for Wireless and Mobile Networks

“…Take the approach in [3] for instance, although several steps from MIPv6 and RSVP are interweaved, the processes of configuring QoS and mobility management during handover are still independent. The reservation can not be installed until the registration information generated by the MN has propagated across the network.…”

“…The mobility management and QoS management can be coupled in three levels: de-coupled, loosely-coupled, and closely coupled. However most of the work is extending one specific QoS model, e.g., [8], [1], [3] proposed various enhancements on RSVP, and [6] summarizes the RSVP extensions for real-time services in wireless mobile networks. Yoon, et al [9] proposed a QoS supporting mechanism in mobile/wireless IP networks using a DiffServ model.…”

A hierarchical agent assisted MIPv6 handover scheme with QoS support

Proceedings of the 3rd International Conference on Quality of Service in Heterogeneous Wired/Wireless Networks - QShine '06

2006

This paper proposes a hierarchical mobility management architecture providing adaptive QoS control to improve the performance during mobile handovers, especially break-before-make handovers. In the proposed scheme, the information for QoS configuration and location management is carried by the same set of messages. The interactions between the QoS Agents (QA) enable smooth handover, with better performance in terms of IP layer handover latency and QoS configuration latency when the MN is away from the home network.

“…[4] provided an evaluation of mobility and QoS interaction. The authors of [3], [6], [5], and [7] proposed approaches for specific QoS models.…”

Towards Minimizing Service Degradation during MIPv6 Handovers

Proceedings. 2006 31st IEEE Conference on Local Computer Networks

2006

Since the correspondent registration messages in MIPv6 go through all the nodes that are responsible for QoS configuration after handover, we propose to extend the Binding Update (BU) messages of standard MIPV6 to carry schemedependent QoS data. Correspondent registration is performed by these new Agent Update (AU) messages. The AU messages are intercepted by QoS Agents, which are located in the "critical" nodes that are responsible for QoS configuration. Thus by the time that the correspondent registration is complete, the QoS configuration has also been updated along the data path, which minimizes the service degradation due to handover. This approach also provides a unified solution for heterogeneous QoS schemes that may be applied along the data path.
