摘要
数据融合技术是无线传感器网络中的关键技术。提出了一种动态自适应制数据融合机制(WADA),该机制主要思想是根据接收到的数据应答包数量,动态调整最大延迟时间,并最大延迟时间按照递减规则分配至各层节点,以平衡数据的准确性和实效性。OPNET仿真结果表明,WADA数据融合机制可以有效地收敛到最佳的最大延迟时间。
Data aggregation is one of the key technology in wireless sensor network. A wait-time adaptive data aggregation scheme （WADA） is proposed. The main idea is to adaptively adjust maximum wait time based on the number of data responses and allocate the wait time to the node in each layer degressively as well as balance the accuracy and effectiveness. Simulation results on OPNET show that WADA could converge to the best maximum wait time effectively.
