A zigbee data encapsulation and analysis method based on the characteristics of the submitted data

Abstract

The invention relates to the technology of wireless sensor networks, discloses a ZigBee data encapsulation analysis method based on the features of submitted data, and solves problems that a conventional ZigBee data encapsulation analysis technology causes a large amount of redundant information when the conventional ZigBee data encapsulation analysis technology is used for APS frame data encapsulation, and the transmission of the redundant information wastes the energy of a terminal node battery. The scheme of the invention can be summarized as a scheme comprising the steps: storing the type of the data encapsulated at this time during the encapsulation of application frame data; analyzing the type of the application frame data before entering the encapsulation of APS data frame encapsulation: directly entering the encapsulation of NWK frame data without APS frame data encapsulation if a state is a continuous submitting state, and enabling an NWK frame sequence number not to change in the encapsulation of NWK frame data; directly transmitting a NWK load to an application layer for application frame analysis during the encapsulation of NWK frame data if the NWK frame sequence number is not changed.

Description

technical field [0001] The invention relates to wireless sensor network technology, in particular to a method for encapsulating and analyzing ZigBee data based on the characteristics of reported data. Background technique [0002] In the past 20 years, with the vigorous development of Internet of Things technology and applications, the importance of Wireless Sensor Networks (WSN for short) as the sensing layer of the Internet of Things has become increasingly prominent and has attracted international attention. The Massachusetts Institute of Technology's "Technology Review" rated sensor networks as "the first of the top ten emerging technologies that have a profound impact on human life in the 21st century"; domestic authoritative experts also proposed the concept of "the world of things, perception first". Wireless sensor networks can obtain objective information such as physical quantities, chemical quantities, and biomass, and are widely used in national defense, military...
