Abstract

An increasing volume of multimedia traffic carried over the Internet is rapidly demanding quality of service beyond the traditional best-effort. The Integrated Services model relies on the Resource reservation Protocol (RSVP) for signaling and resource reservation. RSVP uses a receiver-initiated reservation mechanism to set up the reservation which imposes the protocol complexity and incurs additional processing overheads on the routers. Hence, many researchers study the light reservation protocol. Sender-initiated and Mobility-support Reservation Protocol (SMRP) is a lightweight signaling protocol. SMRP path retransmission may cause extra delay with Crossover Router (COR) scheme during handoff in mobile environment. In order to make SMRP more suitable for Mobile hosts, we propose hybrid method to combine the advantages of COR scheme with Pointer Forwarding scheme. We have selected ns2 Java version network simulator to test it. Simulation result shows that the hybrid scheme reduced the delay time, drop probability and also can provide better system efficiency. SMRP will be more suitable for Mobile hosts when using hybrid scheme.
