Problems solved by technology

[0008]In the practical application of wireless sensor networks, the use of window technology is an important mechanism to deal with data flow problems, but window technology can easily lead to data accumulation, thus Cause subsequent data delay processing or data loss, resulting in discontinuity of system data

Embodiment Construction

[0035] The present invention will be further described below in conjunction with specific examples.

[0036] as attached figure 1 As shown, when the data is transmitted from the wireless sensor network, for the data source that continuously generates data, the data is read by a sliding window with a fixed time interval, and then the data read by the sliding window with a fixed time interval is merged and sorted. The obtained merging results are divided into tasks by sampling, and finally the obtained tasks are sent to the attached load balancing thread, which is attached to the load balancing thread for task assignment.

[0037] When using the sliding window to read data as attached figure 2 As shown, there are generally two types of sliding window technologies at home and abroad: fixed window size and fixed time interval. The sliding window with a fixed size is the most widely used sliding window. The sliding window with a fixed window size refers to fixing the window size...

Abstract

The invention relates to a multi-data-stream processing method based on a wireless sensor network, comprising the following steps of: reading data from a data source generating data continuously by adopting a sliding window with fixed time intervals; merging and sorting the data read by adopting the sliding window with fixed time intervals; then carrying out task split on the obtained merging result in a sampling way; and finally sending the obtained tasks to a load balancing thread for task allocation. With the method, in-time processing of data, no accumulation or overflow of a data stream and the data continuity are ensured, and the loss of the data is reduced as much as possible.

Description

technical field [0001] The invention relates to a method for processing multiple data streams in a wireless sensor network. . Background technique [0002] The Internet of Things embeds and equips sensors into various objects such as power grids, railways, bridges, tunnels, roads, buildings, water supply systems, dams, oil and gas pipelines, etc., and then integrates the Internet of Things with the existing Internet to realize human society. Integration with physical systems, in this integrated network, there is a super powerful central computer group, which can manage and control the personnel, machines, equipment and infrastructure in the integrated network in real time. On this basis, human beings can Manage production and life in a more refined and dynamic way to achieve a "smart" state, improve resource utilization and productivity levels, and improve the relationship between man and nature. [0003] Wireless Sensor Networks (WSN), as the basis of the Internet of Thin...
