Application of LDPC Codes to Networks |
Internet is no longer just about emails and websites. It has become the critical medium of communication and entertainment and keeps on growing larger and larger day by day. Internet serves the society with the entire major needs like education, finance and business. The network performance has become a vital ingredient in businesses. Such rapidly growing internet make the network management increasingly important. The more and more emphasis is actually held on speed, connectivity and reliability. The dependence on the network connection by individuals or the enterprises will break down catastrophically if any problem occurs with the internet. The major problems with the internet these days are network efficiency and congestion. Because of such network congestion, the quality of service to the users gets deteriorated. Congestion leads to retransmissions which are considered as high overload. Such increase in transmission results in the packet loss or packet delay causing the applications to retransmit the data and thereby adding more and more traffic which results in further congestion. In order to reduce such retransmissions, the error correction codes are implemented. This research will investigate the ways to reduce the need for retransmission by using more efficient error correction codes. The most efficient form of error correction codes is the Low Density Parity-Check (LDPC) codes. This project involves the implementation of the LDPC codes which will be able to reconstruct a certain number of lost packets at the receiver end without the need to retransmit them again.
