Problems solved by technology

[0004] However, most of the current RFID networks are set up in environments that are difficult for people to reach frequently, especially in harsh environments. The above-mentioned environments will lead to a significant increase in energy consumption, which puts forward higher requirements for the energy saving of RFID networks

Abstract

The invention discloses an RFID network node self-adaptation energy saving method. The method comprises the steps that firstly, RFID nodes are preset according to a plan; secondly, non-standard honeycomb space and adjacent node groups are determined; thirdly, node mode grouping is preset, and node modes are reset; fourthly, node mode changing is carried out according to a mode switching protocol. According to the method, the RFID nodes in an RFID network at the environment background are regarded as honeycomb nodes, the RFID nodes only need to master the information of the RFID nodes and the information of the adjacent nodes, and then the activating or deactivating mode of the RFID nodes can be determined. Meanwhile, environmental factors such as background interference and the dump energy level of the nodes are taken into consideration in the mode switching protocol design, the problem of reliability and energy consumption of the environment RFID network can be effectively solved, and therefore the purposes of increasing the utilization rate of the RFID nodes and prolonging the service life of the RFID network are achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to an RFID network node self-adaptive energy-saving method. Background technique [0002] FID (Radio Frequency Identification) radio frequency identification technology is an automatic identification technology that began to emerge in the 1990s. Radio frequency identification technology is a technology that uses radio frequency signals to achieve non-contact information transmission through spatial coupling (alternating magnetic field or electromagnetic field) and achieves identification purposes through the transmitted information. RFID systems usually consist of electronic tags (RF tags) and readers. The electronic tag stores electronic data in a certain format, which is often used as the identification information of the item to be identified. The reader and the electronic tag can transmit information to each other according to the agreed communication protocol. Usually, the reader se...
