Simulation of Real-time Wireless LAN MAC Protocol
Feng Li · Acta Simulata Systematica Sinica · 2005
OPNET is a powerful network simulator, which can be used to simulate communication systems and predict network performance. The traditional wireless LAN can not be used directly in the industrial areas because of its characteristic of the message’s delay indetermination. Considering the demands of industrial applications, it is introduced a real-time wireless LAN MAC Protocol. The modeling and structure of nodes and modules, and the results of delays for the different types of nodes are presented. The simulation results show that the protocol can satisfy the demand of real-time, and meanwhile the throughput of general nodes are increased due to collision avoidance.
