[riot-users] Technical Report on RIOT

Hi all,

here are some brief and quick annotations to the suggested paper:

- I think the two network stacks in Figure I are mixed up

- The data in Table I seems very optimistic to me: With those memory 
footprint we could not send pakets or use the network, we also have no 
stdout support, etc. Contiki and TinyOs both support multithreading. I 
never heard about supporting c++ in our system and I think it cannot be 
achieved on a msp430. What do you mean with full c support, we're not 
fully POSIX compatible, we are even not fully newlib compatible and 
cannot achieve even one of those.

- Contiki supports preemptive scheduling.

- We only support MCUs with vectored interrupt controllers and I rarely 
heard about MCUs without one.

In general the paper reads more like a marketing whitepaper than a 
scientifical paper to me.

Best regards,

P.S.: could you please add thomas to this mailing list.

> a technical report on RIOT is currently in the making. The current

> The report analyzes and compares, in a qualitative fashion, existing 
> operating systems eligible to power IoT devices, to conclude that none 
> of them is appropriate to serve the whole spectrum of 
> devices/requirements making the IoT. The report thus motivates the 
> design of a new OS that provides all the necessary features, and 
> outlines the key characteristics of RIOT which fulfill all the 
> requirements identified in the report.
> Your feedback on this report would be very useful. In particular, 
> discussions on the following points would be great:
> 1 - suggestions for how to potentially develop this qualitative 
> analysis further, and
> 2 - suggestions on what comparative measurements to carry out now, in 
> order to complement this qualitative analysis with an appropriate 
> quantitative analysis.
> Looking forward to your feedback!
> Best,
