    Adaptive RSVP Path Fast Handoff Scheme in Wireless/Mobile Networks

    • 摘要: 在移动IP和RSVP相互集成的方案中,为减少RSVP路径切换延迟,降低端-端路径代价,公共路由器的选择是一个关键.提出了一个适应的公共路由器选择算法(adaptive common router selection algorithm,ACRS),在满足应用连接QoS(quality of service)需求的前提下,利用控制参数λ在RSVP路径切换延迟和端-端路径代价之间取得平衡.通过与其他相关RSVP路径切换方案的性能比较,结果表明ACRS可以支持适应的、快速的RSVP路径切换.

       

      Abstract: Among the schemes of mobile IP and RSVP integration, common router's computation is the key to reduce RSVP path handoff delay and end-to-end cost. In this paper RSVP path handoff schemes in IP networks are studied, an adaptive common router selection algorithm(ACRS) is represented, which satisfies application's quality of service (QoS) requirement, and balance between RSVP path handoff delay and end-to-end cost is kept via control parameter λ. In ACRS, optimum common router (OCR) is selected by two steps. Firstly, the node in previous path, which is nearest to new arrived node, is selected as common router, if the nodes are more than one; the nearest node to correspondence host is selected as CR. The RSVP path through CR between new arrived node and correspondence host must satisfy application's QoS requirement. Secondly, the RSVP path through CR between new arrived node and correspondence host is inspected, if there exists an zigzag path, then CR is re-selected, otherwise the selected CR is OCR. Through the performance comparison with other RSVP path handoff schemes, the results of experiment show that ACRS can support fast and adaptive RSVP path handoff.
