Embodiment Construction

[0025] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0026] see figure 1 , the present embodiment provides a Bluetooth network-based multi-mesh-ring topology control method, the topology control method includes the following steps:

[0027] S101. Select a coordinator from the master device;

[0028] S102. Calculate the number of piconets by the coordinator;

[0029] S103. Establish a multi-mesh-ring scatternet;

[0030] S104. Execute a hybrid routing strategy. The hybrid routing strategy includes active routing and self-routing, wherein the active routing is used for internal data transmission in each of the mesh-ring subnets, and the self-routing is used for different mesh-ring subnets. Data transfer between ring subnets.

[0031] Such as figure 2 As shown, the multi-mesh-ring sc...

Abstract

The invention relates to the technical field of Bluetooth networks, and discloses a multi-mesh-ring topology control method based on a Bluetooth network and a storage medium. A multi-mesh-ring scattering network comprises more than two mesh-ring sub-networks, and each mesh-ring sub-network comprises a plurality of main devices and an internal network bridge; the topology control method comprises the following steps: selecting a coordinator from a master device; calculating the number of piconets through a coordinator; establishing a multi-mesh-ring scattering network; performing a hybrid routing policy, wherein the active route is used for internal data transmission of each mesh-ring subnet, and the self route is used for data transmission between different mesh-ring subnets. According to the invention, the multi-mesh-ring scattering network can be created, the shortest path routing in the mesh-ring sub-network and the self-routing algorithm of different mesh-ring layers are executed by starting the hybrid routing strategy, so that the load balance in the network is realized, and the data transmission performance of the network is ensured.

Description

technical field [0001] The invention relates to the technical field of bluetooth network, in particular to a bluetooth network-based multi-mesh-ring topology control method and a storage medium. Background technique [0002] Bluetooth It is a wireless technology standard that uses UHF radio waves in the ISM band of 2.4-2.485GHz to realize short-distance data exchange between different devices. A Bluetooth network is a network formed by multiple Bluetooth devices connected via Bluetooth, and the Bluetooth network topology is developed from the "home network" situation. Assume that portable devices, smart meters, home appliances and plug-in electronic devices need to create ad hoc networks through their Bluetooth modules. After the boot process, each user operates on the device and expects a "network connected" message, and each device can exchange the information it has collected. A high-level description of home networking applications can be achieved through an efficien...
