Energy-Efficient Compressed Sensing in Cognitive Radio Network for Telemedicine Services

Algorithm 2

Priority scheduling algorithm.

1. While the CH receives data from WBANs in the cluster

2. Examine each piece of information from the WBANs.

3. Sort the packets in descending order of their values.

4. The packets with large values (critical data) are given higher priority than other packets.

5. if no higher priority data is processed

6. Send higher priority packets to the server from all clusters

7. else

8. Send less important packets

9. if a higher priority packet arrives at the cluster head

10. Stop sending lower-priority packets; send that higher-priority packet, then resume sending other packets

11. end if

12. end if

13. end while
