Algorithm 2 Proposed Algorithm
1.	Initialize:
2.	r = current round
3.	Begin
4.	for r = 1:max
5.	if the sensor network operating normally
6.	The sensors nodes are clustered
7.	if the sensor in the cluster adopt cooperative strategy
8.	The sensor node decides their own state according to the game strategy
9.	else
10.	Calculate the number of penalty rounds M
11.	Mark the ID of the nodes and punish M rounds
12.	end if
13.	else
14.	End of simulation
15.	end if
16.	end for
