Dynamic Resource Reservation Ordering Based on Signal Prediction Priority Queuing in All-IP Mobile Networks

摘要

QoS in wireless mobile network is one of the hottest topics recently, while RSVP protocol is a key technology. The cell is becoming smaller to provide more service, making handoff more frequent. It is necessary to reserve resource to guarantee QoS during handoff. Moreover, priority ordering is important when many mobile hosts need to reserve resource. This paper presents a dynamic ordering algorithm based on signal prediction priority queuing (SPPQ) to efficiently reserve resource for many mobile hosts. Simulation result shows that the presented algorithm not only guarantees fast handoff but also accomplishes efficient resource reservation, and the limited resource is assigned more effectively.
