Improving performance of TCP for wireless network using SDN

This paper addresses the problem of non-optimal performance of Transmission Control Protocol (TCP) over Wi-Fi networks. TCP considers packet loss as a signal for congestion leading to reduced sending rate. This idea works well for the wired networks where majority of the packet losses are due to congestion. However, in wireless networks, packets are mostly lost because of transmission errors and mobility of the end hosts. Also, when packets are...
