按照文献《complex networks》中192-193页方法生成的scale free network，有详细注释。此方法有助于理解scale free network的生成原理，并画出了P（k）图，可以自己验证r值是否正确。(According to literature " complex networks" in the 192-193 page method to generate the scale free network, with detailed notes. This approach helps to understand the generation of scale free network theory, and plotted the P (k) diagram, you can verify their r value is correct.)

【代码功能】基于Matlab实现Leach协议，Low Energy Adaptive Clustering Hierarchy protocol (LEACH) 【代码逻辑】Nodes that have been cluster heads cannot become cluster heads again for P rounds, where P is the desired percentage of cluster heads. Thereafter, each node has a 1/P probability of becoming a cluster head in each round. At the end of each round, each node that is not a cluster head selects the closest cluster head and joins that cluster. The cluster head then creates a schedule for each node in its cluster to transmit its data. All nodes that are not cluster heads only communicate with the cluster head in a TDMA fashion, according to the schedule created by the cluster head. They do so using the minimum energy needed to reach the cluster head, and only need to keep their radios on during their time slot. LEACH also uses CDMA so that each cluster uses a different set of CDMA codes, to minimize interference between clusters.
