Sensor network architecture, and networking and information interaction method

Abstract

The invention relates to field of communication, and discloses sensor network architecture, and a networking and information interaction method. In the invention, the sensor network architecture comprises N edge nodes, M intermediate nodes and a gateway node, wherein N and M are natural numbers greater than or equal to 1; sensors are arranged on the edge nodes for collecting information; the intermediate nodes are used for collecting the information collected by the edge nodes; the gateway node is used for aggregating the information collected by the intermediate nodes, wherein within a communication cycle, the gateway node performs information interaction with at least one intermediate node, and each intermediate node performs information interaction with at least one edge node; and the gateway node, the intermediate nodes and the edge nodes are in a sleep state within time periods excluding information interaction time slots. By adoption of the embodiment of the invention, when all nodes in a sensor network do not participate in the information interaction, the sleep state can be kept for a long time, thereby saving the energy consumption of the network and prolonging the service life of the network.

Description

technical field [0001] The invention relates to the communication field, in particular to a sensor network architecture, networking and information interaction method. Background technique [0002] With the development of communication technology, wireless sensor network technology gradually shows broad application prospects, and has had a huge impact on social life. The wireless sensor network is composed of a large number of cheap satellite sensor nodes deployed in the detection area. It is a multi-hop self-organizing network system formed by wireless communication. The purpose is to cooperatively perceive, collect and process the perceived objects in the network coverage area. information and send it to observers. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: In the existing sensor network, no matter whether it participates in the process of information interaction or not, s...

Problems solved by technology

[0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the prior art: in the existing sensor network, no matter whether it participates in the process of information interaction, some nodes will be required to be in the working state for a long time, and the larger the network, the The larger the number of nodes that do not enter the sleep state, the higher the energy consumption of the network. These non-sleep nodes must be powered by the power supply for a long time. If battery power is used, the network life will be extremely low, which limits the use of wireless sensor networking Scenes
