Performance Comparison of Low Latency Mobile IP schemes 1

This paper investigates the performance of two low latency handoff protocols proposed by the IETF, namely pre- and Post-Registration. These protocols use Layer 2 triggers to reduce the built-in delay components of Mobile IP. We propose a simple analytical model that allows to assess the packet loss and the delay characteristics of these protocols. Their scalability properties are investigated by means of an OPNET simulation model and their implementation using IEEE802.11 as link layer is also discussed. 1
