网络编码理论是当代信息论的重要组成部分,移动特设网络(MANET)是由一组带有无线收发装置的移动终端组成的一个多跳临时性自治系统,利用网络编码理论解决MANET中最小能量多播问题是无线通信中新的研究热点之一。文中阐述了网络编码基本理论在无线通信中应用的技术原理,然后通过构建无线网络节点分层模型分析了基于网络编码的MANET最小能量求解过程,为解决该类型网络中能耗问题提供新的视角。
Network coding theory is an important part of contemporary information theory. Mobile ad hoc network (MANET) is a multi-hop ad hoc autonomous system composed of a group of mobile terminals with wireless transceivers. It uses network coding theory to solve the problem of minimum energy in MANET Broadcasting is one of the new research hotspots in wireless communication. In this paper, the principle of network coding basic theory applied in wireless communication is expounded, and then the minimum energy of MANET based on network coding is analyzed by constructing a hierarchical model of wireless network node, which provides a new perspective for solving the energy consumption problem in this type of network .
