  ABSTRACT: In the near future, wireless and mobile users will have increased demands for seamless roaming across different types of wireless networks, so it's a significant issue of how to guarantee the quality of service (QoS) and support a variety of services. In this paper, we propose RSVP extensions for real-time services to guarantee the QoS with RSVP in heterogeneous wireless networks. We set an intersystem, "QoS agent" between the gateways of wireless local area networks (WLANs) and cellular networks to manage the mobility of mobile users, and use the schemes of resource pre-reservation and precise pre-reservation decision mechanism to reduce the delay time of re-routing while handoff occurs and guarantee the QoS of real-time services efficiently. Simulation results show that our proposed approach can reduce 52% waste of the whole network resources as the number of the WLANs is set to forty

  ABSTRACT: In the near future, wireless and mobile users will have increased demands for seamless roaming across different types of wireless networks, so it’s a significant issue of how to guarantee the quality of service (QoS) and support a variety of services. In this paper, we propose RSVP extensions for real-time services to guarantee the QoS with RSVP in heterogeneous wireless networks. We set an intersystem, “QoS Manager,” between the gateways of wireless local area networks (WLANs) and cellular networks to manage the mobility of mobile users, and use the scheme of resource pre-reservation to reduce the delay time of re-routing while handoff occurs and guarantee the QoS of real-time services efficiently. Simulation results show that our proposed approach can reduce 52% waste of the whole network resources as the number of the WLANs is set to 40.
