摘要
针对太赫兹通信组网仿真技术,以太赫兹超高速无线MAC协议为核心,基于OPNET仿真平台分层设计并开发了网络级、节点级和模块级三重仿真模型,降低了模型开发难度,提高了仿真效率。重点阐述了采用OPNET仿真平台实现太赫兹组网通信的设计和开发思路,实现了波束赋形及天线对准、天线扫描、自适应入网与退网、CSMA/CA以及TDMA等核心功能。最后,对该仿真模型和搭建的多节点太赫兹网络通信的性能进行了仿真,证明了所设计的组网仿真模型的合理性和高效性。
Aiming at the simulation technology of terahertz communication networking,this paper takes the terahertz ultra-high-speed wireless MAC protocol as the core,design and developeda layerd simulation models of network-level,node-level and module-level and based on the OPNET simulation platform.This approach reduces the difficulty of model development,improves simulation efficiency,focuses on the design and development ideas of using OPNET simulation platform to realize terahertz networking communication,and realizes beamforming and antenna alignment,antenna scanning,adaptive network access and exit,CSMA/CA,TDMA core function.Finally,the simulation model and the performance of the built multi-node terahertz network communication are simulated,which proves the rationality and efficiency of the designed network simulation model.
