SCTP(Stream Control Transmission Protocol) is a new IETF transport protocol over the IP network. Transport protocol is responsible for reliable delivery of a message form a host to another host. We implemented an efficient file transfer system using the SCTP multiple file transfer and modified STCP congestion control mechanism for heterogeneous ubiquitous environment to improve end-to-end FTP efficiency. The result shows that proposed system reduces transmission latency for huge data and improves the performance.
