The presented scheme is capable of increasing transmission efficiency by reducing occupied time slots yet with high decoding suc-cess rates. Unlike existing state-of-the-art distributed rateless coding schemes, the proposed rateless network coding can dynami-cally recode by using simple yet effective XOR operations, which is suitable for M2M erasure networks. Simulation results and analysis demonstrate that the proposed scheme outperforms the existing distributed rateless network coding schemes in the scenar-io of M2M multicast network with heterogeneous erasure features.展开更多
