Abstract
Mobile IP (MIP) could be deployed in a wireless cellular network so that the integrated Cellular Mobile IP (CMIP) network can be used to support datagram delivery to mobile users. In order to provide QoS for realtime traffic in IP network, Resource reSerVation Protocol (RSVP) is needed to reserve network resources along the route which the datagrams follow. However, current RSVP fails to operate through the MIP tunnel. Moreover, the high registration rate in a CMIP network greatly degrades RSVP performance. In this paper, an Indirect RSVP (IRSVP) over Virtual Cluster Cellular Mobile IP (VCCMIP) is proposed in which an assistant RSVP connection is introduced to assist the end-to-end major RSVP operation over the MIP tunnel. IRSVP signaling costs and packet loss rates are evaluated. Simulation results show that the proposed scheme can greatly increase RSVP performance in terms of packet loss and RSVP connection active percentage.KeywordsInternet ProtocolMobile HostPacket Loss RateHome AgentForeign AgentThese keywords were added by machine and not by the authors.
