Abstract: Technique of L2-trigger allows greater support for real-time services on a Mobile IPv4 network by minimizing the period of time when a Mobile Node is unable to send or receive IP packets due to the delay in the Mobile IP Registration process. But when to trigger L2-triggers is not clearly. In this paper, we’ll give a trigger method based on forecast of channel quality and qualify its validity by simulating.

Key words: L2-Trigger, trigger method, prediction of channel quality

摘要: 为了使移动IP可满足实时应用,有文献提出采用二层触发器的方法提前触发三层切换,但是却未能提出明确可行的触发方法,本文通过对移动节点切换过程中信道质量的变换的研究,提出了基于信道质量预测的触发方案,并且通过计算机仿真进行了验证。
