基于OPNET的通信网络半实物仿真方法研究

OPNET作为网络仿真软件具有仿真功能,但基于OPNET的半实物仿真方法的研究较少.对几种基于OPNET的通信网络半实物仿真方法进行了系统的介绍和分析,比较了方法的优缺点,并探讨了半实物仿真需要注意的问题;最后对一个基于OPNET的通用的通信网络半实物仿真环境进行了介绍,并实现了一个具体的移动自组织网络的半实物仿真,取得了良好的效果.仿真方法的研究成果能够广泛应用于OPNET网络环境与其它HLA仿真系统、各类真实网络节点、电台等信道传输设备的互连及其综合仿真验证分析.

Research on Hardware in Loop Simulation of Communication Networks Based on OPNET

OPNET has powerful simulation function as a network simulation software,but the research on HILS(Hardware In Loop Simulation)based on OPNET is lacking.Several methods of HILS of Communication Networks based on OPNET are introduced and analyzed,of which the merits and shortages are compared,and some important issues in HILS are noted.Furthermore,a universal HILS environment of communication networks based on OPNET is given,and a HILS of MANET(Mobile Ad-hoc Network)is carried out.The results could be widely applied in connecting the OPNET with other simulation systems based on HLA(High Level Architecture),or real network nodes,or radio transmitters.
