基于物理层网络编码的无线网络路由协议

摘要

Most traditional routing protocol designs to reduce or avoid interference. So it can not take advantage of the physical-layer network coding and causes the throughout of the network can not be improved. A wireless network routing protocol based on Physical-layer Network Coding(PNC) is proposed. Through the cooperation between network layer and physical layer to enhance the node's interactability. Compared with non-coding and network coding strategy, the integration of physical layer network coding and routing protocol improves the network throughput by 50% and 28% respectively.%传统路由协议的设计都是尽量减少或避免信号传输的互相干扰,无法发挥物理层网络编码的优势,导致网络吞吐量不能得到提升.为此,提出一种基于物理层网络编码的无线网络路由协议,通过网络层与物理层的跨层协作增强节点的交互能力.仿真实验表明,与无编码、直接转发的网络编码策略相比,该协议分别能提高50％和28％的网络吞吐量.
