We propose and estimate a novel transport layer mobility management scheme: Seamless IP diversity based Generalized Mobility Architecture (SIGMA). SIGMA provides seamless handover for mobile hosts and is based on Stream Control Transmission Protocol (SCTP), which is a new dependable transport protocol to transport SS7 signaling messages over IP network. We also show that our handover scheme can greatly reduce the handover latency, packet loss, signaling costs and improve the whole system’s throughput compared to the popular Mobile IP based handover schemes.
