Problems solved by technology

Therefore, at this time, the packet interval time channel in the time channel is applied to the traceability transmission in WSN. This transmission method based on the packet interval time channel is to embed the traceability information into the packet delay, and the packet interval time is a Continuous physical variables, susceptible to interference from network events, so less immune to interference
Moreover, in WSN, nodes will sleep and wake up regularly, so there are limitations in applicability

Abstract

The invention relates to a traceability data energy-saving transmission method in the field of wireless sensor networks. According to the method, a coding mode of a time channel taking pseudo packet identifier arrangement of a data packet and data field size change of the data packet as media is used as a transmission method; namely, the node converts the traceability information to be transmittedinto the pseudo packet identifier arrangement of the data packet and the size of the data packet for transmission, and a base station recovers the traceability information according to the pseudo packet identifier arrangement of the data packet and the size of the data field of the data packet. Compared with the prior art, the method has the advantages that more energy is transmitted on the basisof the original bandwidth; traceability information can be efficiently transmitted, so that the effect of saving energy and bandwidth is achieved; the influence of timing dormancy and awakening conditions of nodes is avoided; and the application range is wide.

Description

technical field [0001] The invention relates to the field of wireless sensor networks, in particular to an energy-saving transmission method for traceability data based on a time channel. Background technique [0002] Wireless sensor network (WSN) is an ad hoc network composed of a large number of miniature, low-power wireless sensor nodes with sensing, processing and communication functions. These nodes obtain data (such as humidity, temperature, pressure, etc.) There are many types of sensors, so it is necessary to evaluate the reliability of the data received by the base station. In WSN, traceability records the generation and transmission process of data, which is an important basis for evaluating the credibility of received data. Traceability can be divided into: linear traceability and convergent traceability. Linear traceability means that the data packet is generated by the data source node, and other nodes only transmit the data packet to the base station (BS) in...
