An RSVP connection renewing scheme using address of neighbor routers in mobile IP-based networks

We propose an RSVP connection renewing scheme using address of neighbor routers to improve the performance of the renewing time of RSVP connection without increasing the number of RSVP connection hops in Mobile IP-based networks. In the proposed scheme, Next HOP (NHOP) is added to each router to record an address of neighbor router. SEARCH message is defined to know which existing RSVP connection is still available after handoff of MN. In the tree network, since the existing RSVP connection has the highest availability, the proposed scheme can reduce the renewing time of RSVP connection without increasing the number of RSVP connection hops. Moreover, the proposed scheme can reduce the number of RSVP connection hops by using the router's own routing table information and own NHOP in the mesh network. The computer simulation results show that the proposed scheme can reduce the renewing time of RSVP connection without increasing the number of RSVP connection hops.
