Abstract: A high-efficiency and low-delay data transmission algorithm based on decoding anticipate (HLDA) is proposed to address the problems that there exist large overhead for broadcasting beacon which carrys coding coefficient matrix and the destination nodes wait a long time to decode in the hub-based forwarding using network coding in delay tolerant networks(DTN). The HLDA proposed a new mechanism of anticipating decoding by hub nodes is presented in HLDA to decrease the end-to-end delay and proposed a unicast and broadcast mixing mechanism to decrease the overhead. By decreasing the coding coefficient matrix interaction mechanism to further reduce overhead. Simulation results show that HLDA can reduce the overhead and average end-to-end delay as compared to the Hubcode.
