    Performance Analysis of Binding Update in Mobile IP during Handoff
    (Springer Berlin Heidelberg, 2004) Tandjaoui, Djamel; Badache, Nadjib; Bouabdallah, Abdelmadjid
    Mobile IP protocol was proposed to handle users mobility on Internet. However, Mobile IP suffers from many drawbacks especially handoff latency. In this paper, we investigate the loss of successive binding update requests and their impact on handoff latency. We show that handoff latency increases in case of successive binding update requests loss. We propose an enhancement of binding update in Mobile IP. It consists on reducing the timeout to half just after the loss of the first binding update. So, the mobile node sends two binding update requests within a timeout. By doing so, we increase the probability that one binding update request reach the home agent. We present an analytical model of handoff latency based on packets loss probability. The simulation shows that our solution reduces considerably the additional handoff latency induced by successive binding update requests loss.
