If we consider a geographical zone of 1 square km and we consider the massive access problem in an IoT network. How many devices should we have in this zone to reasonably say that we have a massive access problem in the IoT network?
I read in some website that the number should be at least 20000 devices per km^2.
Do you know any reference scientific paper that discusses this ?
Thanks.
Dear Zoubeir Mlika,

Hi Zoubier,
In addition to population density, both transmission cycle and retransmission rate should be considered for the design.
" Obviously these requirements are highly expected for the IoT networks operated in high population density cities, where a large portion of IoT end-devices will be deployed. For example, as shown in the table below, the population density in Chennai, India is 25,854 per Km2. If in average it is assumed that one IoT device per capita and the coverage of one IoT base station is 4 Km in radius, the number of the served IoT devices per base station is expected to be 25,854 x 3.14 x 16 = 1,298,905. This means, considering a 30-minute period and assuming that there is no retransmission in a 4 km IoT network deployed in Chennai, India, the expected access capacity is 1,298,905 access per 30 minutes. "
Here is one reference and answer to your question.

which I discussed from a more implementation perspective.
Cheers.
