Abstract
IP based IEEE 802.11 wireless networks are ideally suited for providing high data rate connectivity to pedestrian mobile users moving over small geographical areas like airports, university campuses and hotels. Range of 802.11 access points is limited due to technology constraints and replication is required to provide coverage over even small areas. This situation leads to frequent handoffs. In this paper we have proposed and implemented a cross layer approach for providing fast and proactive handoff using Dynamics HUT Mobile IP. This handoff mechanism works on reducing both the layer 2 and layer 3 discovery phases which are major contributors towards the overall handoff latency. Mobile node is made fully equipped with the information about the neighboring access points and mobility agents before the handoff process is executed. Handoff process is totally controlled by a user space application and is proactive in nature. The proposed handoff mechanism reduces the overall handoff delay to less than 250ms. The proposed approach has been tested and evaluated on experimental testbed setup for the purpose. Performance of the handoff approach has been evaluated for VoIP, audio/video streaming and TCP bulk traffic.
