Embodiment Construction
[0022] Below in conjunction with embodiment the present invention is described in more detail.
[0023] The method for restricting transmission to enhance the performance of the 802.11 distributed coordination function, the steps are as follows:
[0024] Step 1: First, the user terminal equipment is equipped with a wireless network card and a module for limiting the probability of transmission rate. The wireless network card is equipped with the IEEE 802.11 protocol, and the user terminal equipment passes through a basic access mode or The RTS / CTS access method accesses the wireless LAN to become a site in the network;
[0025] Step 2: the access point in the wireless local area network invokes its internal estimation module to estimate the number of stations in the network with the maximum likelihood estimation method, and broadcasts the data to all stations in the network;
[0026] Step 3: Next, each network station in the wireless LAN sends the broadcasted number of networ...
