Development was then funded by Université Grenoble Alpes, Grenoble INP / UJF, throught AGIR 2013-2014 WalT project.
The following projects are also tightly linked to the WalT platform (co-funding, experiments on WalT):
ANR IRIS - Reseaux Tout IP pour le Futur Internet d'Objets Intelligents (2011)
FP7 ICT CALIPSO - Connect All IP-based Smart Objects (2011)
ANR DataTweet - un service public de communications opportunistes (2013)
Persyval SPREAD - Plateforme pédagogique pour l'expérimentation sur des systèmes massivement distribués (2015)
A WalT platform can be qualified with the following adjectives.
You can 'plug' any OS image on WalT nodes. And WalT provides what you need to create such an image, or adapt an existing one. Someone will use an IoT-oriented image to drive sensor boards connected on USB. Others will add a java virtual machine on the image and run distributed data management scenarios.
The other factor for versatility is that you can completely adapt the platform shape to your needs. Usually, one will use small size deployments for debugging or mobile demos, and a large size one for final experiments.
WalT is based on RaspberryPiSBCs, PoE switches, and a standard PC for the server. There is no specific hardware.
A WalT platform costs less than 100$ per node.
Easy to use
The demos should prove this point.
Easy to install
We provide a USB image to install the server, a minimal SD-card image for raspberry pi nodes, a USB image to turn a PC into a walt node, and complete installation procedures.
OS images of WalT nodes can be shared on the docker hub. This is the case for default images. This helps to collaborate with other users.
The development of WalT is open source. Anyone interested is welcome to contribute!
