Abstract
Transmission Control Protocol (TCP) is a predominant transport layer protocol for data transmission over internet. TCP being touted as the “protocol that saved the internet” due to its widely acclaimed congestion control algorithm, has started choking with the advent of challenges faced in the decentralized Multi-hop Ad Hoc Networks. Most notably, the burstiness of this congestion control mechanism has often lead to heavy link layer contentions over ad hoc networks. Such intense contentions pave way to misinterpreted route failures, frequent timeouts and unnecessary retransmissions which dramatically reduces the throughput. In this paper, we propose a cross layer transport protocol (CLTSP) to minimize the intra flow contention and also to improve the spatial reuse. CLTSP performs rate controlled transmission to prevent self-contention among data packets by spacing them out at an appropriate interval. The time interval between the deliveries of successive data packets is dynamically measured based on four hop propagation delay and an appropriate correction factor that are collected from intermediate nodes. We evaluate the performance of our protocol with TCP New Reno and show significant improvement in terms of throughput, end to end delay, Link layer collisions and control overheads.
传输控制协议(TCP)是互联网上主要的数据传输层协议。由于其广受好评的拥塞控制算法,TCP被吹捧为“拯救互联网的协议”,但随着分散的多跳自组织网络面临的挑战的出现,TCP开始受到阻碍。最值得注意的是,这种拥塞控制机制的突发性经常导致ad hoc网络上链路层的严重争用。这种激烈的争用会导致路由错误、频繁的超时和不必要的重传,从而大大降低了吞吐量。在本文中,我们提出了一种跨层传输协议(CLTSP),以减少流内争用并提高空间重用。CLTSP采用速率控制传输,以适当的间隔间隔数据包,防止数据包之间的自争用。根据从中间节点收集的四跳传播延迟和适当的校正系数,动态测量连续数据包发送之间的时间间隔。我们用TCP New Reno来评估我们的协议的性能,并在吞吐量、端到端延迟、链路层冲突和控制开销方面显示出显著的改进。
