General context of IoT

Internships in Internet of Things

Internet of Things (IoT) growth …

• Unprecedented growth of connected devices:

20~46 billions(*) devices expected in 2020

(*) The Future X Network book, §11 – The future of the Internet of Things

• Promise of a new era of digital services

… but limited usage of IoT devices

• People buy connected devices for a limited experience

• Standard users do know:

1) How to configure the network to use them properly;

2) What services they can offer together;

3) Which software to get the best service experience.

How to better leverage available connected devices in personalized services?

IoT control & service management Internships in Internet of Things

Need for digital assistance in IoT !

1. Communication control between IoT devices

• Need for flexible network configuration layer

• Software-Defined LANs = on-demand, dynamic &

secure dedicated micro-networks for devices

2. IoT service recommendation

• Universal description of IoT service classes to guide end-users in finding the right objects in the right spaces for their requested IoT services

Focus on physical functions and their interactions

• Coupling with the network configuration layer:

Application-agnostic Remote Connection Manager (RCM)

- An abstract layer on top of BLE Protocol Stack

- Provides a transparent connectivity to remote BLE devices - Has no impact on the Bluetooth applications nor the Bluetooth peripherals

- Easy to deploy: RCM is purely software and can be installed as an update of the Bluetooth Protocol Stack

- Offering real-time communication between clients and remote peripherals as if they were in proximity

- Doesn’t rely on complex infrastructures, dedicated hardware nor advanced network features

- Implemented under Bluez 5.43 (Official Bluetooth Protocol Stack for Linux) and tested on real devices

- Open source under GPLv2 license

- Research paper published at IEEE INFOCOM HotPOST’18

”Application-agnostic remote access for Bluetooth Low Energy”

Connectivity is said transparent when the native applications can access both local and remote short-range devices without any modification

Internships in Internet of Things

• Mandatory technical skills: C programming, Linux, low-layer programming, very good knowledge of network protocols (TCP/IP stack)

Will be an advantage: Android, short-range technologies (Bluetooth/BLE, ZigBee, etc.), knowledge in drivers and kernel programming, network programming, knowledge in DBus, GIO/GLib …

Other skills:

Autonomous

Ability to work in a team and under deadlines Self-starter and think outside the box

Analytic and Synthetic skills

Excellent organizational skills with attention to detail Opportunity for PhD after the internship
