稻田土壤墒情监测网络分簇策略的研究

The Research of Clustering Strategy in Soil Moisture Monitoring Network System of the Rice Field

通过对分簇路由协议优缺点的分析,在EEUC协议和CADS协议的基础上,结合非均匀分簇和负载均衡思想,提出了一种适合稻田土壤墒情监测网络的分簇策略。该策略根据基站发射功率的不同,将整个网络划分为大小不等的子网,以此构建一个混合型的网络拓扑结构。该网络有效缓解了无线传感器网络中能耗不均匀的"热区"问题。模拟实验结果表明,提出的网络分簇策略可以有效地应用于大规模无线传感器网络中。

Clustering routing protocols is a very important network protocol in the wireless network. In this paper, tlarougn the analysis of the advantages and disadvantages of the more important clustering routing protocol, based on EEUC and CADS protocol, combined with non-uniform clustering and load balancing ideology, this paper carries on a suitable clus- tering strategy of paddy field in soil moisture monitoring network. The strategy divided the entire network into different sizes subnets depending on the base station transmit power, in order to build a hybrid network topology. This net- workeffectively alleviates the uneven energy consumption in wireless sensor networks. The simulation results show that the network clustering strategy can be effectively applied to large-scale wireless sensor networks.
