Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0049] figure 1 It is a schematic flowchart of the implementation of the data collection method in the embodiment of the present invention. Such asfigure 1 As shown, the data collection method may include the following steps:

[0050] Step 101. When the first node determines that the second node is not invalid, the first node calculates the weight value of each data packet to be transmitted corresponding to itself.

[0051] In a specific embodiment of the present invention, before the first node and the second node collect data, the first node needs to determine whether the second node is invalid. Specifically, the first node can first send a communication request to the second node. When the first node receives the communication response returned by the second node within a...

Abstract

Embodiments of the invention disclose a data collection method and a data collection device. The method comprises the following steps that: when a first node determines that the end of a second node is not invalid, the first node calculates the weight value of each data packet to be transmitted corresponding to the first node; the first node determines a first target data packet according to the weight value of each data packet to be transmitted corresponding to the first node; the first node exchanges the first target data packet with the second target data packet of the second node; and thefirst node encodes the second target data packet by means of an incremental code so that the second target data packet collects the first node information of the first node.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a data collection method and device. Background technique [0002] The wireless sensor network is composed of a large number of sensor nodes deployed in the monitoring area through self-organization and multi-hop. The sensor nodes monitor the monitoring area by collecting sensing data. It has the advantages of low power consumption, low cost, easy deployment, no need to connect, and no need to be on duty. It is widely used in environmental monitoring, forest fire prevention, military applications and other fields. [0003] In wireless sensor networks, the data collection protocol is mainly designed through routing technology. In the data collection protocol relying on routing technology, some sensor nodes in the network need to have and maintain the topology control information of the entire network. Once a failed node occurs, the network topology will also cha...
