Midway through the 1970s, the Transmission Control Protocol (TCP) was created as a way to enable reliable communication between host-running applications. With changes in network characteristics, TCP has undergone various iterations to improve its performance over the ever-changing networks. With a steady increase of 13.3% Compound Annual Growth Rate (CAGR) forecasted in the connected car industry until 2030, the need for efficient and reliable communication is at an all-time high. However, traditional TCP faces significant challenges in Vehicular Ad Hoc Networks (VANETs) including frequent disconnections and high latency. The purpose of this study is to evaluate the performance of several TCP versions over scalable VANETs, including TCP Hybla, TCP Vegas, TCP Veno, TCP Westwood+ and TCP LEDBAT. Evaluation criteria include End-to-End latency, Throughput, Packet Delivery Ratio and Energy used during communication with Road Side Unit (RSU). Upon simulating the network, it was shown that TCP Vegas exhibited superior performance in terms of throughput and end-to-end delay, TCP LEDBAT demonstrated superior performance in terms of packet delivery ratio, and TCP Hybla demonstrated superior performance in networks with limited energy resources.
