摘要 针对ZigBee网络中在节点空间占有率很大的情况下存在的数据冗余及能耗较大的现象,提出了将数据融合技术中的分批估计算法改进后应用在ZigBee技术中的思想。对ZigBee网络中时间域里的路由开销进行分析处理以及对空间域里的节点的光照强度数据进行融合,提出了一种从时间域的角度分析ZigBee网络性能指标的思想,并且在空间范围内既从传统的网络层角度考虑降低能耗的改进,又从应用层的角度出发,实现提高ZigBee网络的节点利用率以及降低节点能耗的目标。 Considering the data redundancy and large energy consumption in the case of large share of node space, an improved batch estimation algorithm in data aggregation is proposed to be used in ZigBee network. This algorithm is processing routing overhead in ZigBee time domain and fusing light intensity data in ZigBee spatial domain, the algorithm indicates the traditional method to reduce node energy consumption in network layer, also indicates a method in the application layer, so as to achieve to improve node utilization and reduce node energy consumption.
