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。
In order to improve the throughput of the broadcasting system, improve the energy efficiency of the broadcasting system and simplify the transmission protocol, this paper studies the fountain communication protocol based on the fountain code and proposes a broadcasting cooperative communication protocol based on the fountain code so that the purpose of the first successful decoding Node as a collaborative node for encoding and forwarding, to help other destination nodes receive. As can be seen from the simulation results, compared with direct broadcast protocol, the use of co-broadcast communication protocol greatly enhance the system throughput, significantly reduce the probability of disruption, energy efficiency has also been greatly improved.
