Distributed rateless coded collaboration for satellite relay networks

In this paper, we propose a new distributed rateless coded collaboration, named DRCC, for packet transmission in an energy-limited satellite relay network. The rateless degree distributions on primary and secondary links are analyzed by AND-OR tree technique. Linear programming and multi-objective programming are both formulated to find the optimal solutions to minimize decoding error probability under various link conditions. At last, the simulation results demonstrate that our proposed DRCC scheme outperforms existing distributed rateless coding schemes with significantly better performances about packet error rate and system throughput for satellite networks.
