无线传感器网络紧急数据实时融合策略

Real-time Aggregation Strategy for Emergency Data in Wireless Sensor Network

本文提出一种基于紧急数据优先和自适应控制的实时数据融合策略(Real-time Data Aggregation Based on UrgentData First and Adaptive Control,RDAUA)。通过对数据进行量化分级,并按优先级的高低分配传输时隙,融合时自适应调整融合时机,保证紧急数据的及时融合和快速传输。仿真结果表明,RDAUA策略有效地保证了紧急数据的实时处理,且数据的融合精度较高。

Real-time data aggregation strategy is proposed based on emergency data priority and adaptive control.Through the quantification and classification of the data and timing assignments according to the priority level,the strategy adjusts adaptively the aggregation opportunity in time of the aggregation,so as to ensure timely aggregation and rapid transmission of emergency data.Simulation results show that RDAUA strategy effectively ensures real-time processing of emergency data,and has good data fusion accuracy.
