PERFORMANCE STUDY AND IMPROVEMENT TO THE TCP/IP OVER WIRELESS CHANNEL

Summary:
The Transmission Control Protocol (TCP) is the de facto standard for reliable data transmission in the Internet today. While TCP has been tuned to work well over tradition wired networks, its performance over wireless networks is much worse. This performance degradation results mainly from the preponderance of channel error-induced packet losses compared to congestion-induce losses. The adverse effects of wireless bit-errors ion TCP performance arise primarily because TCP misinterprets wireless losses as being due to congestion. We present the design and implementations of a novel protocol, called the ELN-ACK, that through changing the ACK format to successfully distinguish between congestion and channel error-induced packet losses to substantially enhance end-to-end performance. This mechanism has been demonstrated to provide performance improvements across a wide range of bit-error rates.

Goals
The long term goal for this project is to solve the problem of TCP using in wireless channel. The short term goal is finishing the performance studying of ELN-ACK algorithm.
