Simulation Study Comparison of Throughput Performance between UDP and TCP

Abstract

User Datagram Protocol (UDP) and Transmission Control Protocol (TCP) are a transportation layer routing protocols which are considered of the core protocols of the internet protocol suite. The behaviour of these routing protocols with different network metrics and scenarios is still not very clear.Also the unfairness problem is keep getting worse because of the greedy nature Transmission Control Protocol (TCP).In this simulation study for evaluating and understanding the unfairness problem in WLANs by investigating the Throughput. by used a very popular simulation tool called Network Simulator 2 (NS2).     The simulation tool has used can generalize the effect of TCP and MAC architectural features while maintaining the complex interactions of architectures and algorithms typical of real computer network systems. The used simulation tool is considered an accurate tool for predicting the performance of real-world networks.
