Abstract
The paper focuses on quality of service (QoS) provision schemes in wireless access networks. In allusion to the limitations of mobile IP in fast and efficient handoff, it is proposed a QoS solution of micro-mobile IP and RSVP loosely coupled-advanced weak dynamic resource reservation protocol (AWDRSVP).This mechanism can minimize resource reservation delays and signaling overheads, which combines signal prediction priority queuing (SPPQ) algorithm to perform basic resource reservation in advance. It enhances efficiency and auto-adaptability of resource reservation in micro-mobility area. The Simulation on RSVP and HAWAII coupling platform indicates that AWDRSVP can ensure better QoS of real-time data transmission during handoffs comparing with other RSVP extending schemes.
