| 摘 要： | 为了提升广播系统的吞吐量,提高广播系统的能量效率,简化传输协议,文章研究了基于喷泉码的广播通信协议,提出一种基于喷泉码的广播协同通信协议,令最先成功译码的目的节点作为协同节点进行编码转发,协助其他目的节点接收。从仿真结果可以看出,与直传广播协议相比,采用协同广播通信协议使系统的吞吐量大幅提升,中断概率显著降低,能量效率也有较大提高。

| Abstract: | To further improve the throughput and energy efficiency and simplify the transmission for broadcast system,the broadcast protocols based on fountain codes are analyzed in this paper.We propose a cooperative broadcast protocol based on fountain codes that let the first decoded destination node reencodes the packet and forward to the other destinations to assist the receipt of other destination nodes.From simulations we can see that compared to direct broadcast transmission,the throughput and energy efficienc... |
