Problems solved by technology

The network of wireless sensor networks is unstable and unreliable, the hardware capabilities of the nodes themselves are limited, they are prone to failure or failure, the signal processing is not accurate enough, coupled with modeling errors, external noise disturbances, and so on for its subjective cognition and objective measurement processing technology Due to the limitations of level and means, there are many data uncertainties related to sensor measurement and information processing in wireless sensor networks.

Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings.

[0046] A method for reducing power consumption of a WSN system, characterized in that: comprising the following steps:

[0047] (1) Arrangement of wireless sensor network: Arrange ordinary nodes and base station nodes required by the network in a natural environment, and use ZigBee network technology to realize networking and LAN communication; the ordinary nodes are used for data collection and routing and forwarding of data packets, The base station node is used to deliver the data gathered by common nodes to the upper computer for use;

[0048] (2) The format design of the data package: the data is uniformly encapsulated according to the format of Table 3:

[0049] Data packet header type: according to the application type of the sending data packet, the sending source node is responsible for the corresponding production;

[0050] Destination network address: the ne...

Abstract

The invention discloses a method for reducing power consumption of a WSN (wireless sensor network) system. The method includes the steps of WSN layout, data packet format design, initialization of partial functions of a WSN, and data packet filtering and screening. By the method for reducing power consumption of the WSN system, energy consumption of nodes in the WSN can be reduced effectively, and life cycle of the WSN is prolonged.

Description

technical field [0001] The invention relates to WSN (Wireless Sensor Network) technology, in particular to a method for reducing power consumption of a WSN system. Background technique [0002] Because the wireless sensor network works in a relatively harsh environment, the node energy is generally supplied by the battery, and the power supply cannot be replaced; however, the survival time of the wireless sensor network needs to be as long as several months or even years, so the limitation of node energy becomes its biggest constraint factor . [0003] The sensor node is the basic unit of WSN, and the hardware platform composed of it is closely related to the specific application requirements, so the design of the node will directly affect the performance of the whole WSN. WSN usually includes sensor nodes and sink nodes (SinkNode); a large number of sensor nodes are randomly deployed in or near the sensing area, and can form a network through self-organization. Sensor node...
