Abstract

The number of applications that are using ad-hoc interface is increasing continuously. This effect in diverse quality requirements such as delay, bandwidth, jitter, and reliability. Transmission Control Protocol (TCP) allows two hosts to establish a connection and switch streams of data. User Datagram Protocol (UDP) is a connectionless protocol that is used mainly for low-latency applications. In-Stream Control Transmission Protocol (SCTP) we can transmit several data streams between two endpoints when a network connection established at the same time. Due to the various constraints such as mobility, flexibility, and reliability, TCP and UDP don't perform well in ad hoc networks. This paper gives the performance evaluation of TCP, UDP, and SCTP regarding various quality metrics using ns2. Simulation results prove that SCTP performs better than TCP and UDP regarding throughput, jitter, loss rate, packet delivery ratio, and end-to-end delay in ad hoc networks.
