Network coding is a network packet transmitting protocol, applied to increase the achievable throughput for the exchange of information between two terminals through one relay. Throughput efficiency this paper reviews latency and bandwidth efficient coding algorithm based on principles of network coding for retransmitting lost packets in wireless multicast network. It outlines the basic principles and important techniques for retransmission of packets in network coding.Network coding is new paradigm that allows the intermediate nodes in a network to create new packets by combining packets received on their incoming edges. The main application of the networking coding technique includes content distribution, peer to peer networks, and wireless ad-hoc networks.Such network is characterized by highly dynamic set of users and frequent topological changes. There are two main advantages of Network coding approach are potential throughput improvements and a high degree of robustness.
