Research on networks simulation technology of channel access protocol
信道接入协议的网络仿真技术研究

By using OPNET simulation platform, the modeling and simulating technology for channel access protocols based on ALOHA and CSMA/CD were studied. Modeling hierarchy framework of ALOHA and CSMA/CD was constructed, and their network model, node model and process model were realized. By analyzing the simulation results of channel throughout and utilization, the rationality and effectiveness of the simulation model was evaluated, so as to prove the feasibility of this networks simulation technology.
