Abstract:

Handoff performance is one of the important metrics in mobility management where frequent handoff can occur in single session and that may degrade the performance of TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) in wireless data networks. Cellular IP is one of the dominating IP micro-mobility management protocols. It supports two types of handoff schemes, hard and Semi-soft handoff. In this paper, an enhancement to the existing hard handoff mechanism in Cellular IP is proposed and subsequently assessed by simulation. The approach proposed in this paper, called Forward-Based Handoff Mechanism (FBHM), constitutes a new handoff mechanism in Cellular IP to reduce packet loss and enhance the UDP and TCP performance. The simulation results show that the packet loss of UDP traffic is reduced to zero. It also shows that the performance of TCP is improved in comparison with hard handoff.
