Overview of this book

Bluetooth Low Energy (BLE) is a Wireless Personal Area network technology aimed at novel applications for smart devices. High-tech BLE profiles and services are being increasingly used by application developers and hardware enthusiasts to allow devices to interact with the surrounding world. This book will focus on a technical introduction to BLE and how it is reshaping small-distance communication. We will start with IoT, where many technologies such as BLE, Zigbee, and IEEE 802.15.4 Mesh will be introduced. The book will present BLE from an engineering perspective, from which the protocol stack, architecture, and layers are discussed. You will learn to implement customized projects for Peripheral/Central communication, BLE Beacons, indoor navigation using triangulation, and the Internet gateway for Bluetooth Low Energy Personal Network, all using various code samples and APIs on Android, iOS, and the Web. Finally, the book will conclude with a glimpse into future technologies destined to be prominent in years to come.

Preface

Mesh networking in wireless technologies


Theoretically, the traditional mesh topology is applicable to any kind of communication network, but it is mostly used in wireless technologies. If a new node is joining, it can join the network without any need for a physical wired connection, which makes it perfect for fast-changing networks (for example, vehicular networks). The implementation of this topology is limitless, but as of this chapter, we will see how it is useful for:

  • Wireless mesh networks
  • ZigBee
  • Bluetooth Low Energy

Wireless mesh networks

WMNs were one of the earliest adoptions of mesh technology. Alongside Wireless Ad-hoc Networks, they established a very practical foundation of mesh networking. By successfully implementing routing algorithms, WMNs were able to implement the technology on an industrial level. 

WMNs have a similar topology to mobile ad hoc networks, but they show slow or no mobility. In WMNs, a change in the topology occurs when a host leaves the network. WMNs also do...
