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
