Problems solved by technology

[0009] Most of the data research on mobile sinks focuses on how to reduce the data collection delay of sink nodes, but the time-space correlation of data is not considered when collecting data, so the collected data has a large similarity, so it is wasted network resources thereby shortening the life cycle of the network

Abstract

The invention discloses a wireless sensor network mobile sink data collection method based on dynamic estimation of data value, and belongs to the field of sensor networks. The invention includes constructing a data spatial distribution diagram in combination with the historical data, and determining the data collection sequence for the sensing nodes in the sensing network based on the data spatial distribution diagram, so that the sink node is configured according to the data The collection sequence completes data collection of the sensing nodes in the sensing network. By constructing a data spatial distribution diagram, the spatiotemporal correlation of data is included in the considerations of sink nodes for data collection, thereby avoiding the possibility that the collected data will not be able to obtain objective results due to large similarities in the collected data, and reducing the use of network resources. Waste, prolonging the life cycle of the network.

Description

technical field [0001] The invention belongs to the field of sensor networks, in particular to a mobile sink data collection method of a wireless sensor network based on dynamic estimation of data value. Background technique [0002] Wireless sensor networks are now widely used in environmental monitoring, underwater monitoring, wildlife protection, building health monitoring and monitoring reports on large ancient sites. Data collection is one of the most important tasks of these applications. There is a big difference between the long-term monitoring of large-scale earthen sites in the field using wireless sensor networks and general-purpose scenarios. First of all, large-scale earthen sites in the wild generally exist in areas far from cities, with the characteristics of large coverage and complex geographical environment. If the method based on multi-hop forward is used, it is easy to cause energy holes, which greatly shortens the life cycle of the network. Secondly, ...
