Performance evaluation during handover in WLAN network with different transport protocol variants

This paper describes and makes an analysis of performance of Stream Control Transmission Protocol (SCTP) compared with Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) over Mobile IP (MIP) using Network Simulator (NS-2). This new transport layer protocol has recently been accepted by Internet Engineering Task Force (IETF) as a proposed standard to address a number of TCP limitations. We conduct the simulation study of the three transport protocols in 802/11b WLAN network. The performance analysis was done over mobile-IP network environment that enables to measure the several performance metrics such as throughput, packet delay and the number of sent and loss packets.
