当payload大小增加时,Thread和Zigbee性能要优越于Bluetooth mesh 随着网络规模变大(节点的增多),relay变得非常重要 - 延时随着网络大小增加而变大,但由于Bluetoothmesh基于广播模式,延时受影响最大 - 在大网络情况下Bluetoothmesh可以通过优化relay来提高性能 本文主要摘自: silabs < AN1142: Mesh Network Performance Comp...

Bluetooth adopted a simple, yet powerful approach for developers to describe what a node on a Bluetooth Mesh network is and does so that it can interact with other nodes. This approach is based on a set of building blocks called models. Models consist of a collection of features with defined...
由于蓝牙mesh支持payload较小导致吞吐量降低 3.1.2 延时对比(4跳时) 结果: 在payload较小时,三种网络的表现类似 当payload增加时,Thead分包(6LowPAN)效率和验证性能最佳 Zigbee协议支持应用层分包,因此效率也不错 蓝牙mesh随着payload大小增加而延迟和效率降低,因为蓝牙mesh支持的数据包太小,导致分包太多,传输效率变慢。
蓝牙mesh的协议栈是层级结构。 最低层就是BLE层, 就像一开始介绍的蓝牙mesh建立在BLE物理层和链路层之上,采用Advertising和Connection两种数据传输方式。 承载层(bearer):承载层定义了如何使用底层LE栈堆传输PDU。目前定义了两种承载,Advertising Bearer和GATT Bearer。 网络层(network):网络层定义了各种消息地址类型和网...
Subnets– Subnets are a mechanism which allow a Bluetooth mesh network to be partitioned. This is primarily for security purposes but it does also have the benefit that messages sent using a subnet are not relayed beyond that subnet. This conserves energy. ...
Ultra-compact footprint, low-power consumption, long-range, or ultimate RF sensitivity – Silicon Labs has the optimal solution for every application. All of our Bluetooth modules and SoCs provide the same developer experience, so you can future-proof mesh network designs and evolve your applicatio...
测试应使用在片上系统和网络协处理器 (NCP) 模式下运行的不同设备类型执行。先前的测试发现这些运行模式之间的一些差异,因此应进一步表征。 下载阅读完整的Bluetooth Mesh性能测试报告:https://www.silabs.com/documents/public/application-notes/an1137-bluetooth-mesh-network-performance-cn.pdf...
Model Bluetooth Mesh in MATLAB MathWorks Bluetooth® Toolbox enables the creation of a Bluetooth mesh network with the Create, Configure, and Visualize Bluetooth Mesh Network example. Each network node models several of the Bluetooth mesh protocol layers, pictured in blue in Figure 1....
