WoT-Arrowhead-Drawbridge

This is an Arrowhead Drawbridge project, that is a part of the Thesis WOT ARROWHEAD DRAWBRIDGE: BRIDGING HETEROGENIC IOT-BASED SYSTEMS. It consists of wot_emulator and arrowhead_drawbridge which both run on Node.js.

WoT Emulator

This program emulates different IoT devices creating Web Things by Eclipse Thingweb node-wot framework and register them as a service on Eclipse Arrowhead framework.

How to run the program in the terminal by following CLI commands:

• type the path to the directory where is wot_emulator: cd home/yourusername/path/to/src/wot_emulator
• enter npm install to install package.json
• run npm run start

The devices with their locations and values can be defined in devices.json file.

Arrowhead Drawbridge

This program implements a rule-based engine that can connect IoT-based systems.

How to run the program in the terminal by following CLI commands:

• type the path to the directory where is arrowhead_drawbridge: cd home/yourusername/path/to/src/arrowhead_drawbridge
• select the pull or push mode by setting true or false and define pullInterval in milliseconds in the file config.json
• enter npm install to install package.json
• run npm run start

The rules are in the descriptors directory.

Emulating the processes

How to test the processes:

• set true in test and define interval in milliseconds in the file config.json that is located in the wot_emulator directory.
• if there is selected pull mode, first run wot_emulator and then arrowhead_drawbridge.
• pull mode requires setting true in file config.json that is located in the wot_emulator directory. First execute arrowhead_drawbridge and then wot_emulator.
