The popular CDMA 1x EV-DO service is a service that provides high speed always on internet connectivity to the subscribers in a wide-area mobile environment. 2.4 Mbps/153 Kbps is the peak upload/download specified, but the application-layer throughput, which the user experiences , has not been evaluated well.

Introduction
The Code Division Multiplexing Access (CDMA) 1x EVolution-Data Only (EV-DO)
is finalized by the 3GPP and the Telecommunications industry association as the next generation standard for the high soeed internet ....etc

Abstract
Applications that require good network performanceoften use parallel TCP streams and TCP modificationsto improve the effectiveness of TCP. If the network bottleneckis fully utilized, this approach boosts throughput by unfairlystealing bandwidth from competing TCP streams. Improvingthe effectiveness of TCP is easy, but improving effectivenesswhile maintaining fairness is difficult. In this paper, we describean approach we implemented that uses a long virtual roundtrip time in combination with parallel TCP streams to improveeffe ....etc

Improving the Performance of TCP Over Wireless Links

In this thesis, we address the problem of degradation in performance of TCP over wireless links. We propose enhancements to TCP so that it responds to certain control signals from the network. These control signals allow TCP to differentiate packet losses unrelated to congestion from those related to congestion. This enables TCP to react appropriately to different packet losses resulting in improved performance. We developed a network simulator for evaluating the performance of our ....etc

The Highly variable round-trip times (RTTs) in wireless networks causes spurious timeouts which can be a reason for the unnecessary retransmission and the thus unnecessarily degrading throughput for the Transmission Control Protocol (TCP).The methods to improve TCP throughput in wireless networks is discussed in this article. One of the method involves the use of a retransmission timeout (RTO) threshold which is slightly higher than the standard. The other method described involves the use of selective repeat (SR) and go-back-N (GBN) as retran ....etc

Abstract:
The communication requirements for space missions necessitate to address the problems due to deep space communication networks. the effects of slow start algorithm, propagation delay and the page link errors on the throughput performance of transport layer protocols are investigated in deep space communication networks. The objective of this seminar is to demonstrate through existing TCP protocols are far from satisfying the deep space communication requirements and point out the urgent need for new TCP solutions. ....etc

Improving TCP/IP Performance over Third-Generation Wireless Networks
The (3G) wireless networks with high data rates is gradually being deployed. The Transmission Control Protocol (TCP) must be optimised to perform in these networks. This will have a broad and significant impact on data application performance. The parts described in this chapter are :
-adapting to the significant delay and rate variations over the wireless channel and
-a wireless channel and TCP-aware scheduling and buffer sharing algorithm
Windo ....etc
