Channel Access-Based Joint Optimization of AoI and SINR under Attack: Game Theory and Distributed Approach

Algorithm 1.

Channel access strategy for the sensor node under attack

Input:: the iteration times set; : the available channel set for the active sensor node; : initial mixed strategy of each sensor node ; : the active sensor node set in the current slot; : the learning step size.

Output:: the final mixed strategy of the active sensor node ; the AoI utility ; the SINR utility .

1: For the iteration time do

2:   If the sensor node is inactive

3:   Do nothing, i.e. :

4:   Else

5:   Perform the SLA algorithm, i.e.

6:   Derive the normalized payoff by (12)

7:    If

8:

9:    Else

10:

11:   End

12:   End

13:   Record based on (9)

14:   Record according to (10)

15: End
