采用网络编码的广播传输效率分析
Efficiency Analysis of Broadcast Transmission Using Network Coding
摘要
Abstract
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.关键词
