TCP Performances over Wireless Link deploying Delayed ACK

Understanding the impact of TCP techniques toward wireless environment is important because the need of mobile devices have been significantly increased. Often, many studies showed that wireless environments have crucial impacts to TCP performance. Yet, the effects of delayed acknowledgement over wireless link have not thoroughly been studied. This paper, therefore, investigated the impact of delayed acknowledgement of TCP connection over wireless link focusing not only throughput but also the bandwidth and energy consumption. Those metrics are crucial to wireless networks. The variations used in this study, widely implemented and experimented, are Reno, Newreno, Sack (Selective acknowledgement), Vegas
