The 802.11 standard specifies a carrier sense multiple access with collision avoidance(CSMA/CA) protocol. In this protocol, when a node receives a packet to be transmitted, it first listens to ensure no other node is transmitting. If the channel is clear, it then transmits the packet. Otherwise, it chooses a random "backoff factor" which determines the amount of time the node must wait until it is allowed to transmit its packet. During periods in which the channel is clear, the transmitting node decrements its backoff counter.

模糊聚类方法，用相关系数法构造模糊相似关系矩阵r，构造了模糊等价评判矩阵，为了方便下载者使用，把代码进行了优化，可直接把矩阵带进去使用。(Fuzzy clustering method, using the correlation coefficient method to construct the fuzzy similarity relation matrix r, construct a fuzzy equivalence evaluation matrix, in order to facilitate the download to use, the code has been optimized, can go directly to the matrix with the use.)

The signal received by a user over the forward link in such a high data rate system contains interference from the neighboring base stations. we note that the strength of this interference is a function of the network load in the neighboring cells. we obtain an expression for the received SINR (Signal to Interference and Noise Ratio) as a function of the traffic load in the interfering cells. Using this result, we propose an improvement to the SINR estimation scheme that is implemented in the current cellular data network. The proposed scheme provides a more accurate estimate of the user SINR by taking better account of the contribution of inter-cell interference. It builds on top of the current SINR measurement scheme by using a combination of pilot measurement and traffic load measurement
