In this paper, we describe a transport layer mobility scheme termed Cellular SCTP, or cSCTP for short, based on the stream control transmission protocol (SCTP), for seamless soft handoff. We compare mobile IPv6 and two of its variants (mobile IPv6 with fast-handover and hierarchical mobile IPv6) with cSCTP on various aspects (especially the handoff process of micro-mobility). We also analyze the mobile IPv6 handover mechanism in detail to reveal the operations that constitutes extra delays or packet losses caused by handoffs. Furthermore, we describe the interworking of cSCTP with SIP for mobility management.
