Table 1 AP selection process of IoT devices

The APs broadcast their data utilization Θ₁,⋯,Θ_j,⋯,Θ_N to devices through CC channel every \(T_{AP}, T_{AP} \gg T_{i}, \forall i\in \mathcal {M}\) period.

The devices compute the expected data uploading probability \(\tilde {A}_{i, k}^{s}\) over APs according to equation (16).

For device i,i∈1,⋯,M who selected AP j for data uploading

IF \(\max _{k} \tilde {A}_{i, k}^{s}\geq A_{i, j}^{s}+\epsilon \) do

Device i sends the request to AP k for data uploading.
