Performance analysis of SCTP protocol in WiFi network

The Internet Protocol Stack provides a set of transport layer protocols. There are two dominant types of transport layer protocol used in the Internet: UDP (User Datagram Protocol) and TCP (Transmission Control Protocol). The transport layer provides end-to-end information transfer across a network with the quality of service needed by the application. In this paper, we provide a performance comparison of SCTP, TCP and UDP protocols in WLAN environments for different traffic flow: VoIP, video streaming and data traffic. The performance metrics used for this evaluation include throughput, end to end delay and packet loss rate. The comparison of performance of SCTP, UDP and TCP are done using the network simulator NS-2.
