Abstract

The invention discloses a method, a medium and a system for acquiring a secure multi-hop transmission path of a wireless sensor network. The acquisition method comprises the steps: acquiring a transmission path set from a starting wireless node in the wireless sensor network to a target wireless node through a transit wireless node, wherein the starting wireless node is a sensing node, the target wireless node is a gateway node, and the transit wireless node is at least one level of aggregation node; and determining an optimal transmission path from the transmission path set according to the uplink transmission bandwidth and the signal intensity value of the initial wireless node. According to the embodiment of the invention, under the condition that the power consumption of the sensing node is not increased, the transmission security and the information effectiveness are ensured, the reliability of a wireless network is improved, and the security of a multi-hop protocol is ensured.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a method, medium and system for obtaining a safe multi-hop transmission path of a wireless sensor network. Background technique [0002] At this stage, the wireless sensor network is developing rapidly. In 2015, the number of China Mobile IoT terminals was 700 million, which increased to 1.8 billion in 2018. The CAGR from 2015 to 2018 is about 37%. The compound growth rate from 2019 to 2022 is expected was 12.13%. Various conceptual projects such as the Internet of Things industry, Industry 4.0, smart city, Internet of Vehicles, VR / AR virtual reality, autonomous driving, and 5G Internet of Everything require sensor support. [0003] In traditional wireless sensor communication, the method of realizing access to the network is usually to distribute the aggregation nodes at fixed sites in a certain geographical area. Currently, in a wireless network that supports...
