1. Initialization of queues (△C_q: Critical Queue, △N_q: Normal Queue)

2. Initialization of traffic (T: Traffic, T_p: priority-based traffic & T_n: Normal traffic)

3. Initialization of parameters (T_d: Delaytime, P_t: Propagation time,: Transmission time of data into medium, D_e: End-to-end delay, T_pt: Processing time of T_p at each node, H: Number of hops & O_h: Overhead of each hop

4. While node “K” send “T” to node “K₁” at cluster “L”

5. If T = T_p then

6. Node K₁, putting T_p into △C_q

7. Else if T = T_n then

8. Node K₁, putting T_n into △N_q

9. End if

10. End if

11. Examining delay time “T_d” for △C_q

12. Do // Transmitting data from source to destination

13. If, then

14. Calculate // End-to-End delay for priority-based traffic

15. Else if, then

16. Calculate //: Additional delay for normal queue &: Additional processing time at each node; End-to-End delay for normal traffic
