A Survey on Network Coding Techniques to Solve MTB Problem in Wireless Networks

Bellita Coutinha, Grantha K.N

Advancements in Wireless Communications have attracted the study of Wireless Networks. There are several types of wireless networks such as wireless sensor networks, MANETs etc. which are gaining importance day by day. Broadcasting is a fundamental operation in one such network. Traditional method to broadcast is flooding but flooding causes severe wastage of channel and severe packet collision. To overcome this, advanced technique is Network Coding. Network Coding improves efficiency of transmission. Instead of sending individual packets separately, network coding combines the packets before forwarding them and thereby it reduces the number of transmissions which is referred as minimum transmission broadcast (MTB). In this paper the focus is mainly on the survey of network coding techniques to solve MTB problem for Wireless Networks.
