%X This paper presented a distributed always encoded broadcasting based on network coding (DAEBNC) algorithm to improve energy efficiency in wireless networks. Its main idea was that based on which packets its neighbors had, the sent node chose source packets to generate several linearly independent combinations based on random linear network coding and broadcasts in turn. Then received nodes solved a system of linear equations to decode combined packets and retrieved source packets. Theoretic analysis revealed that encoded packets based on the approach could be decoded in all received nodes, which effectively reduced the number of transmissions. Simulation results indicate that comparing with existing flooding algorithm, this approach can effectively improve energy efficiency and consequently improve the performance of wireless networks.
