Algorithm 1: The SAda Algorithm.
1:	Initialization Parameter: $x_t,{\alpha }_0,{\omega }_0$ and ${\sigma }^2$
2:	for t in T do
3:	Get the location of IoT devices and select the suitable devices as the candidates, update $\mathcal{N}\left(t\right)$.
4:	if none of SUE $\mathrm{n}\in \mathcal{N}\left(t\right)$ has connected to TUE then
5:	Connect to SUE n once.
6:	Update $u_{t,n},k_{t,n},t_n$ .
7:	else
8:	Observe $x_t$ .
9:	for each device $\mathrm{n}\in \mathcal{N}\left(t\right)$ do
10:	Calculate the efficiency function $u_{t,n}$ .
11:	Find device ${\alpha }_t$ ,where ${\alpha }_t=arg\underset{\mathrm{n}\in \mathcal{N}\left(t\right)}{\min }{u}_{t,n}$ .
12:	Update $d_{sum}\left(t,{\alpha }_t\right)$ .
13:	Update $\overline{u}\left(t,{\alpha }_t \right)=\frac{{\overline{u}}_{t-1,{\alpha }_t}{k}_{t-1,{\alpha }_t+d_{sum}\left(t,{\alpha }_t\right)}}{k_{t-1,{\alpha }_t}+1} \left(15\right)$
14:	Update $k_{t,{\alpha }_t}=k_{t-1,{\alpha }_t+1}$
