An Optimal Backoff Time-Based Internetwork Interference Mitigation Method in Wireless Body Area Network

Algorithm 1

Rescheduling algorithm.
Input: Neighbour list of
Output: Collision-free transmission opportunity
1. At the end of the listening period performs the following:
2. Allocate slots
3. for the neighbour list do
4. if there is transmission going on, start rescheduling at ,
    then
5. ⟶collision occurs
6. end if
7. if the next transmission of the is in the rescheduled transmission frame of . i.e., then
8. ⟶collision occurs
9. end if
10. end for
11. for in the rescheduling superframe do
12. The is calculated according to formula (18), and then according to formula (7), the is obtained by .
13. if there is a collision-free time duration starting with for the transmission of then
14. Assign to ;
15. Keep looking for the next slot:
16. ;
17. ;
18. end if
19. end for
20. if collision-free duration is not found, then
21. Switch channel;
end if
