Abstract


The rapid development of information technology, more and more complex as the network structure and size as well as increasingly diverse network applications, network planning and design, research and development of network equipment and networking protocols development has become increasingly difficult, and therefore urgently needed a scientific means to reflect and predict the performance of the network, network simulation technology came into being. Especially in the past 20 years, the rapid development of the system simulation technology, network simulation, intelligent planning, network optimization and management become the hot issues of the field of data network, with simulation technology, can be very effective to improve the reliability of the network planning and design and accurate , significantly reduce the risk of network investment, reduce unnecessary waste of investment. Network simulation in the future will become an indispensable part of the planning and design of the data network. OPNET and tools, in-depth discussion of the simulation modeling techniques, full text focuses on modeling of network protocols and how to implement. In the standard model simulation system based on the analysis of the performance of the agreement, based on the protocol design and improvement program. Highlights the IEEE 802.11 standard MAC protocol functions, and detailed analysis of the main factors affecting network operation performance in the environment of the increase in the number of network stations, the conflict increases and the idle time of the radio channel caused by the waste of resources. On this basis, the more easily achieved in the method can be used to improve the MAC protocol, in order to obtain better performance. OPNET network simulation software for network simulation provides a powerful development environment, but there are some problems with other simulation systems or applications between distributed co-simulation. The high-level system architecture (HLA) is a common architecture developed to meet the needs of large-scale complex systems simulation. HLA's distinguishing feature is to support various types of system simulation, provide a common data exchange communication protocols and common, open data semantic interoperability, phase separation and simulation capabilities with universal support environment, therefore HLA in solving heterogeneous, distributed, collaborative reusable simulation models and simulation system interoperability has made significant progress. This article focuses on the structure of the HLA run support environment (RTI) and how to co-simulation method in the HLA structure.
