“…In [9], an analytical model of the NAK-based multi-copy SR ARQ is developed for performance study of TCP over RLP in cdma2000 systems. However, this work does not consider the correlated fading eects and the channel errors are assumed to be independently and identically distributed (i.i.d.)…”

In this paper we present a cross-layer analysis of wireless TCP systems over correlated channels. The effects of error correlation on the behavior of link retransmission strategy and the end-to-end throughput of TCP layer are investigated. Based on the cross-layer analysis, an efficient refinement of link layer protocol is proposed by consciously utilizing the information of channel correlations, which leads to the performance improvement of wireless TCP systems.

Abstract-TCP has been found to perform poorly in the presence of spurious timeouts (ST) caused by delay spikes which are especially more frequent in today's wireless mobile networks than in traditional wired network. Because STs do not frequently occur in wired networks, and are generally considered to represent a transient state, previous research did not consider the effects of ST on the steady state performance of TCP. However, ST is more frequent in wireless mobile environments, and must be considered explicitly to accurately model the steady state sending rate and throughput of TCP. In this paper, we propose an analytical model for the sending rate and throughput of TCP Reno as a function of packet error rate and characteristics of spurious timeouts. The accuracy of the proposed model has been validated against simulation results. The accuracy of the model has also been compared with previous models, and has been found to be more accurate than previous models in the presence of spurious timeouts.
