AbstractNetwork coding is a new technique that allows the nodes in the network to code the incoming data and transmit. Significant gains such as throughput improvement, robustness, complexity and security can be obtained by using network coding. Dynamic source routing is a reactive protocol for multi hop mobile Ad hoc networks. This paper proposes a better DSR technique using Network coding to reduce the number of transmissions in mobile ad hoc network and increasing throughput efficiency. The simulation results when compared with existing DSR protocol shows potential throughput improvement and communicates more information with fewer packet transmissions.
