Indirect Path Setup: A New Approach for Handoff in HAWAII

Abstract

In the next generation wireless access technologies which are defined to be a pure IP based wireless networks; there are two types of IP mobility management: IP macro-mobility management (intra- domain), and IP micro-mobility management (inter- domain). HAWAII protocol is one of the prominent protocols for IP micro-mobility management. It supports two approaches of path setup handoff schemes: Forwarding Path Setup schemes and Non- Forwarding Path Setup schemes. In this paper, we proposed a new approach for fast path setup handoff in HAWAII. The proposed approach is implemented and evaluated using network simulator ns-2. Then, the performance of the proposed approach is compared against the two HAWAII path setup handoff schemes. The simulation results show that the number of packet loss is reduced to zero and the handoff delay and service disruption are reduced to minimum. The UDP and TCP performance are significantly improved in comparison with other HA WAII path setup schemes. The proposed approach can efficiently support realtime and non-real time applications.
