13.1 Introduction

Wearable devices bring a new experience, which is more intuitive and closer to the living habits, of using technology to ordinary people. That explains why wearable devices grow explosively recently. In response to this trend, lots of major manufacturers, such as Google, Apple, Samsung, and FitBit, make considerable investments in the production of wearable devices. Cisco estimates that there will be 929 million wearable devices globally, growing nearly threefold from 325 million in 2016 [1]. Also, CCS Insight indicates that market for wearable technology will double over the next four years [2]. Those wear devices, including watches, wristbands, hearables, and eye‐wear, are designed to be lightweight and power‐saving; thus, their computing capability is limited. To eliminate the limitation on computing, it relies on a local‐hub to do computing tasks for wearable devices.

The local‐hub, or called coordinator, is mostly a smartphone that processes service requests transferred from wearable devices. The prerequisite of building the connection with the local‐hub, wearable devices need to pair with the local‐hub ...
