Dear RIOT users,

my name is Ahmad kassar, the managing partner of dotcity ltd.
we manage the world's largest portfolio of ".city" domains for the most
populous cities in the world, such as:


I think the best match for smart cities portals on the web is the ".City"
domains, that is why i joined this nice group to know more about the IoT
and Smart Cities,

in case anyone has promising ideas for Smart cities applications, kindly
feel free to contact me so we can talk in more details

good luck for this group, i have enjoyed being a member

best regards

Ahmad Kassar

> Hi RIOTers,

> I have seen several research articles and YouTube videos from different
> conferences and workshops where NDN applications are using RIOT, but not
> much discussion about the application layer data formats used or the naming
> conventions. It seems like SenML+CBOR would be one possibility, but it
> has quite some overhead in the description with an URN which may not be
> necessary with named data.
> Who are working on NDN projects with RIOT?
> I know some of the Berlin people and INRIA seem involved, and some PRs
> from UCLA (Wentao Shang) and FIU (Alex Afanasyev), so I guess there is a
> quite widespread interest in NDN on RIOT. So what kind of experiments are
> you doing? What is the application layer data?
> I want to explore sensor network scenarios with NDN but I don't know at
> what point I should jump in.
> What aspects of the NDN cryptographic security options have been used with
> RIOT so far?
> Has there been any work done on mesh networks with NDN?
> In a mutex network, the forwarded interest packet may need to bounce back
> out the same interface that it was received from in order to reach a device
> with the right data. Is there a risk for broadcast storms? Similar to the
> wizards apprentice syndrome where one packet triggers multiple follow up
> transmissions from other nodes and the network would be filled with
> broadcasts from all nodes.
> Hoping to hear from others doing research in this area,
