Abstract

The invention discloses a wireless sensor network data fusion scheduling algorithm for joint optimization of time delay and power consumption. Firstly, through cluster head node selection and fusion routing trunk tree construction, routing nodes are significantly reduced, and additional data multi-hop transmission is reduced. Power consumption and delay; a two-level transmission power data fusion cluster construction algorithm is proposed. In each fusion cluster, the cluster head node is responsible for the data fusion of the sensor nodes in the cluster; the data of the cluster head is reduced by compressing redundant data and reducing the dimensionality. Transmission volume to reduce transmission power consumption; a data fusion scheduling algorithm within and between clusters is proposed, and factors such as transmission delay and data deposition volume are comprehensively considered to effectively avoid link conflicts and ensure real-time transmission of perceived data.
