摘　　要：针对单源多播网络,为了更有效地运用网络编码技术,在揭示源点编码重要性的基础上,提出源点的多级编码方法,并推导出几个重要的性质。运用提出的方法,解决了单源多播网络编码中的两个问题:其一,可以让不具备计算能力的节点成为网络编码数据传输的宿点;其二,提出一种简单的网络编码加密传输算法。对提出的方法进行仿真测试,仿真结果验证了理论分析的结论。For single source multicast network,in order to use network coding technology more effectively,based on revealing the importance of source coding,a multi-level coding method at source is proposed,and several important properties were deduced.Using the proposed method,two problems in single source multicast network coding were solved.One was that node without computing power could become the destination of network coding data transmission;the other was to propose a simple network coding encryption transmission algorithm.Simulation tests were made to the proposed methods and the simulation results verified the theoretical analysis.
