Inter-ASN Handover Using MSCTP Protocol in IEEE 802.16e Networks

We propose in this paper, to replace the two Layer 3 Handover mechanisms defined for the situation of macro mobility with IP address change in IEEE 802.16e: “Client-MIP and Proxy-MIP”, by the new protocol created specially for the mobility without services interruptions: “MSCTP”, which has the peculiarity to support several IP sessions at the same time.The purpose of this proposal is to reduce the latency and avoid the interruption of services during the IP address change procedure by the mobile station.We compare simulation results, done with NS2 [1], between MSCTP, PMIP and CMIP protocols under the context of simple and full mobility.
