Abstract

As wireless networks are evolving to IP based network, issues to support micro mobility becomes more and more important. One of the prominent solutions to support mobility management is Cellular IP proposed by Columbia University. TCP performance with hard handoff and semi-soft handoff was evaluated by authors of Cellular IP. However, it’s not well known that how TCP performs with Cellular IP and soft handoff. In this paper, we evaluate performance of TCP with various handoff schemes and find that TCP performs well with soft handoff, in general. However, it is observed that combining soft handoff and in-sequence transport of TCP may cause throughput to decrease substantially. We propose method to improve TCP performance with soft handoff by delayed ACK and prediction of RTO. Simulation results show effectiveness of our scheme.
