Method and system for storing sensor network data facing user multiple demands

Abstract

The invention provides a method and a system for storing sensor network data facing user multiple demands. The method for storing sensor network data includes a data storage mode based on data serving as a center is implemented inside a sensor network; and data storage is performed outside the sensor network by using a Sink node, wherein the data storage mode based on data serving as a center also performs a step of building a multi-granularity data storage strategy for a user through an incident rule mechanism before the step of data storage, when the Sink node performs data storage, the Sink node analyzes user inquiry requests to inquire data needed by the user, if the Sink node stores the inquiry data of the user, an inquiry result is returned to the user; and if not, the inquiry requests are sent to the Sink node to perform intelligent analysis to obtain key values of the incident needed by the user, and a data report function of a corresponding storage node is started according to the key value, the data needed by the user are uploaded to the Sink node for storage.

Description

technical field [0001] The invention relates to a data management method of a sensor network, in particular to a data access method and system of a sensor network oriented to multiple needs of users. Background technique [0002] Wireless sensor network (Wireless Sensor Networks, WSN) is currently a frontier hot research field that has attracted much attention internationally. It has very broad application prospects and can be applied to military defense, industrial and agricultural control, urban management, biomedicine, environmental detection, Fields such as emergency rescue and disaster relief and remote control in dangerous areas are considered to be one of the technologies that have had a huge impact on the 21st century. [0003] The wireless sensor network is composed of a large number of cheap micro sensor nodes deployed in the monitoring area. It is a multi-hop self-organizing network system formed by wireless communication. Its purpose is to cooperatively perceive,...
