基于网格的无线传感器网络分簇方法

Grid-based cluster partition method in wireless sensor networks

由于无线传感器网络的能量约束,所以为了延长网络寿命,对无线传感器网络的网络层路由技术的研究至关重要。网络分簇是无线传感器网络中的一个重要研究课题。主要研究传感器节点均匀分布的网络中簇的划分方法,得出了一种能量节省的分簇个数计算方法,提出了一种基于网格的分簇方法。在基于网格的网络分簇模型下给出了两条定理来保证采集的信息可以传输到基站。

Because of the limited energy in wireless sensor networks, the research on routing technology on the network layer is pivotal in the architecture of wireless sensor networks. The research of cluster partition is very important in wireless sensor networks. How to cluster a network where nodes are distributed averagely is studied, how to calculate the number of clusters to economize energy is presented, a grid-based cluster partition method is expounded. At last, in terms of grid-based cluster partition model two theorems are given to ensure that messages is transmitted to based-station.
