在无线随机接入网络中,数据包的冲突是不可避免的。传统上,解决冲突的方法是采用MAC协议控制数据包接入信道和冲突后的重传管理。最近,又出现了采用信号处理技术解决数据包冲突的新方法,这一技术充分体现了信号处理技术与网络技术的融合。文中分析和比较了各种基于协议和基于信号处理技术的冲突解决方法。最后给出了进一步的研究方向与结论。 In wireless random access networks, data packet conflicts are inevitable. Traditionally, the solution to the conflict was to use the MAC protocol to control packet access channels and post-conflict retransmission management. Recently, there have been new methods of resolving packet collisions using signal processing techniques that fully reflect the convergence of signal processing and network technologies. This paper analyzes and compares various conflict resolution methods based on protocol and signal processing. Finally, the further research directions and conclusions are given.
