A Study on Performance of CUBIC TCP and TCP BBR in FANETs

Abstract

Flying ad-hoc networks (FANETs) recently have paid attention regarding to technological progress in the field of wireless network, it has proposed for various purposes including military, surveillance and monitoring of areas, where it is unreachable by a human. With the high demand for continues network connectivity with reliable and robust communication becomes a challenging research topic. In addition, the investigation of routing protocols has done by many researchers, while, to our knowledge, there is no evaluation of TCP protocols in FANETs. According to those issues in this paper, we study the performance behaviors of TCP-CUBIC and TCP-BBR protocols, which are most widely used as a TCP congestion control protocol and most getting attention recently. As well as this study, concern with the investigation whether any of those TCP protocols could provide significant performance benefits over FANETs. Those protocols have evaluated using Network simulator-3 (NS-3), and we have compare the protocols using throughput and Fairness Index under different moving speeds of UAVs and under variety of number of UAVs. As a result, that, those TCP protocols have a poor performance, Although, TCP-CUBIC slightly better performance than TCP-BBR on average, but none of them can help to provide reliable and guaranteed end-to-end data delivery.
