Analysis of SCTP Handover by Movement Patterns

Stream Control Transmission Protocol (SCTP) is a new end-to-end transport protocol, which can be used to support the mobility of mobile terminals. This paper describes a framework of SCTP handover and analyzes the handover latency for the single-homing mobile terminals. We then show the experimental results of the SCTP handover in terms of the handover latency and throughput for the two different movement patterns: linear and crossover patterns. For the linear movement pattern, it is shown that the SCTP handover latency may severely depend on the handover delay at the underlying link layer. In the case of the crossover movement pattern, we see that the throughput of the data transmission could be degraded, as the crossover movements occur more frequently.
