Numerical-analysis

I am doing research in wireless sensor network in data aggregation. here cluster head send packet to base station .by using k means cluster algorthim A network is divided into k layer. k cluster are formed in k layer . each cluster has one cluster head . all cluster member send data to its corresponding cluster head by using TDMA . the cluster head performs the data aggregation and forward packet to base station .

说明：  这个程序和我上传的上一个程序有关，它可以将上个程序收集到的频谱数据进行拼接，从而在全频段进行展示，还能计算频谱上的信号频谱带宽和频点 主要参数 start_freq %扫频中心频率fc的起始频率， stop_freq %扫频中心频率fc的截止频率 rtlsdr_fs %每一次扫频的采样频率，改变他会影响每次扫频的带宽 nfrmhold %每次扫频的帧数 nfft %fft点数 overlap %扫频频谱的重叠率(dataspecrumcatch, catch the spectrum and It can also calculate the signal spectrum bandwidth and frequency point on the spectrum)

k means techniques de classification non supervisée (clustering) les plus utilisées. Etant donné un entier K, K-means partitionne les données en K groupes, ou "clusters", ou "classes" ne se chevauchant pas. Ce résultat est obtenu en positionnant K "prototypes", ou "centroï des" dans les régions de l espace les plus peuplées. Chaque observation est alors affectée au prototype le plus proche (règle dite "de la Distance Minimale"). Chaque classe contient donc les observations qui sont plus proches d un certain prototype que de tout autre prototype
