无线传感器网络中一种高效的安全数据融合协议

Efficient and secure data aggregation protocol for wireless sensor networks

为了降低无线传感器网络能耗,保障网络安全,设计了一种基于模式码的安全数据融合算法。在传感器网络中借助于模式码进行数据融合,保障采集数据的安全,采用模糊算法获取传感器节点采集数据的状态,只将紧急数据和变化了的一般数据的模式码送到簇头进行处理,实现了网络能耗的最小化。

In order to reduce the energy consumption and ensure the security in wireless sensor network, the secure data aggregation algorithm based on pattern codes was designed. Pattern codes were used to make the data aggregation in sensor network to ensure the security of collected data. The estate of data from the sensor nodes were obtained hy fuzzy algorithm, and sensor nodes only transfen＇ed the pattern codes of emergent data and changed usual sensed data to the cluster-head for process, which realizes the minimization of network energy consumption.
