Modeling and Performance Analysis of Channel Assembling Based on Ps-rc Strategy with Priority Queues in CRNs

Algorithm 1

Polling scheduling strategy with reserved channels.

 (A) Priority support stage

1: Start

2: Determine the number of idle channels

3: If

4: Give service to the ongoing until all reach the upper bound

5: Then give service to the ongoing until all reach the upper bound

6: Else give service to the in

7: End if

 (B) Polling stage

8: Start

9: Determine the number of idle channels

10: If is not empty

11: Divide the free channels into and & channels go back to (A).

12: If & channels go back to (A).

13:  Then channels give service to in

14: Else waiting in the queue & channels give service to

15: End if

16: Else channels go back to (A).

17: End if (polling stage is over. The marked release the channel after completing the service.)
