Thanks for sharing! We have analysed similar pattern in many IoT devices and presented periodicity in IoT traffic as FFT (fig 4 - of IoTDI paper attached for reference) and some initial results here in this report: https://www.repository.cam.ac.uk/handle/1810/284092 and full paper is here: https://dl.acm.org/doi/10.1145/3302505.3310082 Best regards, On Thu, Mar 19, 2020 at 10:31 AM Mirjam Kuehne <mir@ripe.net> wrote:

Dear colleagues,

IoT devices often perform activities on a periodic basis. Thymen Wabeke of SIDN Labs shares his analysis of periodic network traffic from IoT lightbulbs. Read it on RIPE Labs at:

Kind regards, Mirjam Kühne RIPE NCC
