Algorithm 1 ACTOR

1:
Upon receiving a DIO, measure RSSI
2:
Initialize the Action Values-Based Equation (5)
3:
for each packet p sent through neighbor $N b r$ do
4:
if $N b r$ not in the neighbor table AND Received ACK then
5:
Add $N b r$ to neighbor table
6:
set $N_{t} (a)$ and ${\bar{X}}_{t} (a)$ to zero for all transmission power settings
7:
end if
8:
if Parent Switch happened then
9:
Reset the learned Action Values
10:
end if
11:
Calculate UCB index and select transmission power based on based on Equation (8)
12:
Select UCB index based on Equation (9)
13:
Transmit packet with selected transmission power
14:
Increment the counter for transmission power a: $N_{t} (a) = N_{t} (a) + 1$
15:
Update $d e m a n d_{N b r}$ from
16:
if packet sent successfully then
17:
the Action Values based on Equation (7)
18:
end if
19:
if packet sent failed then
20:
the Action Values based on Equation (7)
21:
end if
22:
Set the transmission power to $max (U C B, d e m a n d_{i})$
23:
if $A_{t} \neq A_{t - 1}$ (if optimal transmission power changes) then
24:
signals the demand ( $A_{t}$ ) to the parent
25:
end if
26:
