Bluetooth Mesh low-power-consumption node dynamic awakening method

Abstract

The invention discloses a Bluetooth Mesh low-power-consumption node dynamic awakening method, which mainly comprises the following two steps that: 1, a data packet sent to a low-power-consumption node(LPN) by a friend node carries synchronous clock information, and the low-power-consumption node (LPN) performs clock synchronization once receiving data; the friend node can synchronously update thedynamic awakening time of the low-power-consumption node, and data can be sent to the low-power-consumption node without sending an inquiry data packet by the low-power-consumption node; secondly, the low-power-consumption node is in an awakening state; in the wake-up period, if new information is received, processing is carried out, and then the wake-up time is gradually shortened; and if the new information is not received, gradually increasing the wake-up time. According to the invention, the clocks of the LPN and the friend nodes and the dynamic wake-up time of the LPN can be synchronously updated, the sending of data packets of the LPN is reduced, and the power consumption in the Bluetooth Mesh networking process can be further reduced.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a Bluetooth Mesh low power consumption node wake-up method. Background technique [0002] In a wireless Mesh network, any wireless device node can act as an AP and a router at the same time, each node in the network can send and receive signals, and each node can communicate directly with one or more peer nodes. [0003] The biggest advantage of the wireless Mesh network structure is that if the nearest AP is congested due to excessive traffic, the data can be automatically rerouted to an adjacent node with less communication traffic for transmission. By analogy, the data packet can also continue to be routed to the next nearest node for transmission according to the network situation until it reaches the final destination. [0004] The relationship between Bluetooth Low Energy and Bluetooth Mesh: Bluetooth Mesh is a network technology. The Bluetooth Mesh network ...

Problems solved by technology

However, both approaches have drawbacks

Too long scanning time or too short broadcast interval will lead to increased wake-up time, which will increase BLE power consumption; while BLE devices with connected communication need to maintain connections regularly, reducing the connection interval and increasing the number of connected devices will lead to an increase in BLE connection events. As a result, the BEL power consumption increases
