摘要: The Data Distribution Service (DDS) based on the Publish and Subscribe (PUB/SUB) communication model provides a high flexible data transmission for real-time applications, yet it faces significant challenge achieving reliable multicast. ARQ-based error control adopted in DDS is effective only when channel condition moderately good, also vulnerable to feedback implosion. This paper describes new multicast scheme DDS, called RCRM. First, RCRM employs rateless code, so that can obtain higher efficiency than legacy DDS. Second, novel of considerably enhances coding performance. In particular, publisher finds appropriate points minimize overhead. We implement MATLAB simulator, conduct extensive simulations. results show outperforms other protocols terms overhead decoding completion time.
