摘要 网络编码技术是一项近年来得到高度关注的新技术,它能提高网络带宽的利用率,增强网络传输的安全性,有效降低设备能耗。为此,建立一种无线网络模型,该模型包含一个发送节点和多个接收节点,并且增加了对ACK/NAK丢失出错情况的设计。制定了采用网络编码技术和不采用网络编码技术2种广播方案。通过对2种方案的理论分析和仿真结果表明,网络编码可有效减少数据包传输的次数,提高传输效率。 Network coding is a new technique in recent years, which can increase the bandwidth efficiency and security of communication, and reduce the wastage of energy. This paper creates a wireless network model. The model includes one source and several sinks. The design of ACK/NAK lost is considered in this model, two packet broadcast schemes using network coding or not are presents. Compared whih two packet broadcast schemes, one scheme retransmits the lost packets using network coding, the Other does not use. Theoretical analysis and simulation result show that network coding can decrease the number of transmissions significantly, enhance transmission efficiency.
