摘　　要：传感器网络在农业生产信息采集领域具有一定应用前景,有限的节点资源限制了传感器网络的实际应用。借鉴分簇传感器网络在提升系统吞吐量、降低系统延迟以及节省能量方面显示出越来越大的优势,在农业环境监测传感器网络中引入分簇思想。已有的动态簇形成方案的典型代表是LEACH,该方案存在安全威胁,而且协议没有提供广播认证功能。由于簇首选择及簇形成的动态性使得大多数已有安全方案不适用于分簇传感器网络。该研究在基于分簇的传感器网络协议中加强安全性考虑,引入簇内广播认证机制,提出针对LEACH的安全解决方案,基于该方案的农田信息采集系统传感器网络性能得到有效提高。Wireless sensor networks （WSNs） has a good application future in information collecting field of agricultural production. Sensor nodes are resource-constrained,which limited the practical application of WSNs. Clustered sensor networks have been shown to increase system throughput,decrease system delay, and save energy,which makes us to introduce clustering into WSNs of environmental monitoring system of agriculture production. Those with rotating cluster heads, such as LEACH, have also drawback in terms of security. These clustered based protocals did not provide in-clustering broadcast authentication while broadcast is necessary for the operation of the WSNs. The dynamic nature of their communication makes most existing security solutions are inadequate for them. In this paper,we proposed a security solution that providing in-clustering broadcast authentication for LEACH based protocols ,which can efficiently improve the performance of the WSNs for environmental monitoring of agriculture production based on the proposed scheme.
