Network Coding in Wireless Environment

An approach called network coding is a new research area that could dramatically enhance the reliability and efficiency of practical networking systems. Network coding can enable intermediate nodes to send out packets that are combinations of previously received information. So transmitting evidence about messages can be more useful than conveying messages themselves. There are two main advantages of this approach: improvements in throughput and robustness. This paper is literature survey on network coding in wireless environment. The paper explains what network coding does and how it does it. It also presents practical implementations of wireless network coding in order to show how this approach can be used in realistic scenarios.
