In this paper, we propose a novel multiple access rateless network coding scheme for machine-to-machine(M2M) communications.The presented scheme is capable of increasing transmission efficiency by reducing occupied time slots yet with high decoding success rates. Unlike existing state-of-the-art distributed rateless coding schemes, the proposed rateless network coding can dynamically 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 scenario of M2M multicast network with heterogeneous erasure features.
