Important point one user should belong to distinct cluster not more than one cluster. After grouping MUE (Master User Equipment) is selected by BS on 3 major factors i.e., their willingness to be MUE, SNR and battery percentage, MUE will be given incentives by the cellular operator in term of extra MBs or call credit for this purpose. At any time MUE can leave it role and the among other SUE devices will be selected MUE.

...previously, it could not be developed successfully. So we could never even get to see any foundational functions of the needed application to see if any of it worked decently and successfully. With his help, though, I do have a couple of usable breadboarded sensors comprising ESP32 and MPU6050. (With guidance I can use any other preferred sensor instead). Initially powered by USB, there is a battery connector on the ESP. Sensor firmware programming was done via VS Code, so I have gained a bit of practice using that. The desktop application attempt was I think done in some version of C and using Qt. Previous attempts "might" have been in Python, and I do not know what might be better for the shorter and/or longer terms of project development and expansion. I should hop...
