 "A Comparison of Mechanisms for Improving TCP Performance over Wireless  Links"

 Name       : Swapna Sunkara
 Course     : cs898T
 Instructor : Dr.Chang

 Major Goals :
 ------------
 
  - To discuss and  compare several schemes designed to improve the performance
    of TCP in wireless networks

  - To classify the schemes into three broad categories

  - To discuss about Congestion Control

  - Conclusion

  - Future Work

 Scope :
 ------
 
        Reliable transport protocols such as TCP are tuned to perform well in the traditional
 networks where packet losses occur mostly becuase of congestion. TCP is known to have poor
 performance over unreliable wireless links where packet losses due to transmission errors are
 misinterpreted as indications of network congestion. In this paper we will see that the significant
 losses are due to bit errors and handoffs. This paper also speaks about the different approaches
 to improve the performance of TCP in wireless networks. In this paper the effectiveness of 
 different schemes are examined, compared and the degree of  performance improvement due to each
 are analyzed. 

       In conclusion this paper demonstrates that selective acknowledgements and  explicit loss
 notifications result in significant performance improvements.
