Throughput performance of transmission control protocols on multipath fading environment in mobile ad-hoc network
Istikmal, Adit Kurniawan, Hendrawan Hendrawan · 2017
Transmission control protocol (TCP) ensures the destination received the data. With the congestion control mechanism, TCP play important roles in throughput network performance. Unfortunately, this mechanism has the inaccurately assume about network condition and cause throughput degradation. TCP assumes that packet losses are due to congestion, unfortunately, wireless networks suffer from several types of losses that are not related to congestion, especially in wireless ad-hoc network with the multipath fading environment. In this paper, we evaluate and investigated the congestion control mechanism in TCP Tahoe and TCP Reno at Rayleigh environment, and Two-Ray ground as a comparison propagation model. The result shows the highest degradation of TCP performance is in severe fading, which is Rayleigh fading. For analysis, we used a throughput model to find TCP performance based on SNR (Signal to Noise Ratio) in a Rayleigh fading environment.
