This site contains the material for the ST training in April 2015. Goals are
- to have an overview of IoT architecture and procotols, with a focus on the constrained part of the IoT.
- to obtain hands-on experience:
o service description
o service definition
o service discovery
o service oriented applications
- to prepare for a subsequent in-house project on lighting networks.
The course involves 3.5 days of group work consisting of lectures (morning) and practical work. Work in groups of two.
The course revolves about a service oriented system in which many clients use a collection of services, mimicking vehicles searching for parking lots. The servers are represented by Raspberry Pi’s; clients run on laptops or desktops of yourself. You will need to familiarize yourself with the respective hardware and software.
The course aims to prepare for a lighting project at NXP using IoT technology. Although we will not use really constrained devices in the practical, we want to exercise the protocols. At NXP, constrained devices and constrained networks will be used.
On Friday 14.00 there will be a collective demonstration of an integrated system. Discuss with each other timely the shared information or interfaces that are needed for this. We suggest to appoint an architectural team that makes these choices and makes them known to everyone. Also agree who will present on Friday. Notice that this has the nature of a ‘plugfest’ in which every group has to provide some element.
Write a report in the form of a logbook while you work. It will be judged on two independent metrics: quality and quantity. Indicate in that report what you plan and what the result is. Send the reachers and assistants involved a link with a document that contains this, or a directory. Make sure that your work can be examined easily without any searching. To that end use a compact storyline that explains the logic. Use screenshots, code snippets and diagrams to further explain your work. Extend this during the four days.
