Problems solved by technology

However, in the process of data transmission from the underlying node to the aggregation point, most of the redundant data is not properly processed, but is uploaded multiple times meaninglessly, which increases the energy consumption of network data transmission

Abstract

The invention discloses a wireless sensor network data aggregation method and apparatus based on a perception coincidence rate. The method includes following steps: constructing a node transmission hierarchy chart according to a wireless sensor network; starting to construct an aggregation area from nodes at the highest layer according to a preset aggregation area construction rule and the perception coincidence rate; and sending wireless sensor network data according to the aggregation area, wherein non-aggregation points are preferred as relay nodes in a data transmission process of aggregation points and independent points, and then nodes with high residual energy are selected as the relay nodes. According to the method, redundant data can be fully processed, the energy consumption of data transmission is reduced, the accuracy of the data is guaranteed, the quality of data aggregation is improved, and simplicity and convenience are achieved.

Description

technical field [0001] The present invention relates to the technical field of wireless sensor networks, in particular to a data aggregation method and device for wireless sensor networks based on perceptual coincidence rate. Background technique [0002] In wireless sensor networks, in order to ensure the accuracy of data, a large number of nodes are densely distributed in the network, and the information in some areas is sensed by multiple sensor nodes, thus generating redundant data in the network. If each node independently transmits the data it collects, redundant data will be repeatedly transmitted meaninglessly, wasting network energy resources and shortening the network life cycle. [0003] In the data aggregation of wireless sensor networks, spatial correlation is mainly used in related technologies to divide nodes into clusters, which can deal with redundant data to a certain extent and reduce data transmission overhead. However, if the clusters are only divided a...
