Abstract

Abstract

Application layer mobility is important for IP application under mobile environment. The support of under layer mobility guarantees the smooth of data transaction in handoff, while application layer mobility guarantees higher layer application can transfer and receive data correctly in handoff. MESOCK (Mobile Extension SOCKET) is introduced for application layer mobility, which is an extension of TCP/UDP and let running session using new IP address to transfer and receive data after getting it. So it can let data go to the destination not be forwarded by tunnel. It makes the datas integrity and continuity in the IP changing process. The result of simulation proves that the MESOCK can get the goal well.
