“…Extension of the study to include link-layer retransmission is currently under way. Results on the throughput performance of TCP in the presence of link-layer retransmissions can be found, e.g., in [12,13,20], where on the other hand energy performance is not studied.…”

In this paper, we present a study on the performance of TCP, in terms of both throughput and energy consumption, in the presence of a Wideband CDMA radio interface typical of third generation wireless systems. The results show that the relationship between throughput and average error rate is largely independent of the network load, making it possible to introduce a universal throughput curve, empirically characterized, with gives throughput predictions for each value of the user error probability. Furthermore, the study of the energy efficiency shows the possibility to select an optimal power control threshold to maximize the tradeoff between throughput and energy, thereby potentially achieving very significant energy gains.

“…Several studies have also been made for the cdma2000 (one of the 3G standards) system [1]. The performance of TCP over the cdma2000 RLP was shown in [13]. A negative acknowledgment-based hybrid ARQ scheme was proposed in [21].…”

Abstract-To bring TCP-based services to the mobile devices in a cellular network, it is necessary that TCP be extended over the wireless link. However, the performance of TCP severely degrades in a wireless medium. Hence, radio link protocols (RLPs) are used as an interface between TCP and the physical medium. RLPs fragment TCP segments into frames and use robust error correcting codes and fast retransmission schemes to shield the channel related losses from TCP, thus preventing TCP throughput degradation. In this paper, we show the limitations of the existing RLPs, which do not differentiate the frames generated from the same TCP segment. We claim that if selective frames are made more robust to transmission failures, then the performance of RLP and, hence, TCP can be improved. We identify such decisive frames and categorize them as crucial and noncrucial. Our claim is based on the fact that initial frames can afford a few trials of retransmissions, whereas the later ones cannot. We treat the frames differentially with respect to forward error correcting (FEC) coding and automatic repeat request (ARQ) schemes. We consider specific cases of FEC and ARQ strategies and show the qualitative difference in the performance of the RLP through analysis and simulations. The gain in the performance is more prominent when both FEC and ARQ (hybrid-ARQ) are used. The increase in TCP throughput with the proposed RLP is also demonstrated.

“…In [11] and [12], the dependency of TCP and RLP performance on various RLP conguration parameters in the correlated fading channels are investigated based on model analysis and simulations. The results show that the RLP retransmission conguration (1,1,1,1,1,1) has better performance in highly correlated channels compared with the standard RLP retransmission conguration (1,2,3).…”

“…Since our solution only modies the triggering method of the RLP retransmission, it is independent with the retransmission conguration. In [11] and [12], an improved RLP retransmission conguration [1 1 1 1 1 1] has been proposed to obtain better performance in the highly correlated channels instead of the standard retransmission conguration [1 2 3]. We should point out that our proposed solution is orthogonal with the retransmission conguration enhancement in [11] and [12].…”

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.
