Simulation Study of Distributed WLAN Performance Based on OPNET

This paper introduces the basic concept of wireless local area network, and its advantages and disadvantages. The IEEE 802.11 series standards of WLAN are analyzed. The network model, the node model and the advancement model of distributional WLAN are constructed based on the network simulation platform OPNET. In order to optimize the network performance, the network performance of WLAN under the IEEE 802.11 series standards are studied by setting different network parameters including speed, information packet grouping size. The network delay and the drop rate are reduced. The system throughput is improved. It has important reference value to the choices of IEEE 802.11 series standards and the set of parameter in the future deployment of WLAN.
