无线传感器网络是由许多低成本、低功耗的具有传感、本地处理和无线通信能力的设备组成的。分簇是一种有效的拓扑管理方法，可以提高无线传感器网络的生存时间，降低能耗。本文提出了一种新的动态分簇方法，该方法周期性地产生簇，并根据阈值函数选择簇头。与LEACH协议分簇是静态的，簇头数目在整个场景中是固定的不同，该方法中的CH分布在Land维上，簇的数目可以根据节点的数目动态调整。在MATLAB软件中进行了仿真，并与LEACH、LEACH-C、O-LEACH、LEACH-B、M-LEACH、V-LEACH和W-LEACH算法进行了比较。仿真结果表明，与LEACH算法相比，该方法在节省能量的同时，提高了网络生存时间。在所提出的方法中的聚类数的覆盖也示出。结果表明，在一个测试中，leach协议的网络寿命为1100轮，而所提出的方法的网络寿命为3100轮。
Wireless sensor networks (WSNs) are composed of many low cost, low power devices with sensing, local processing and wireless communication capabilities. Clustering is a useful topology-management approach to improve lifetime and reduce the energy consumption in wireless sensor networks. In this paper we have proposed a new dynamic clustering method where clusters are created periodically and cluster head (CH) is selected based on threshold function. Unlike the LEACH protocol that clustering are static and cluster head number is fixed in the entire scenario, CHs in our method distributed in Land dimensions and the number of cluster can be dynamically adjusted based on the number of nodes. The simulation was performed in MATLAB software and it was compared with LEACH, LEACH-C, O-LEACH, LEACH-B, M-LEACH, V-LEACH AND W-LEACH algorithms. The simulation results show that proposed method have been reduced energy conservation and enhancement of network lifetime comparing with LEACH algorithm. Coverage of the number of clusters in proposed method is shown too. The results showed that in a test network life of leach protocol were 1100 rounds, whereas network life of proposed method was 3100 rounds.
