Future Extensions

1. Create specific channels for each logical channel.
2. Create "T" so more than two devices can communicate.
3. Add implementation option to stop scanning after "X" beacons received.
4. Add implementation to check pending list in create_Acknowledgement instead of in MAC_sublayer.
5. Fix slot transmission step in the transmission of a frame (i.e., the time at which the frame is transmitted). Note the behavior does not change. This is strictly a timing issue.
6. When matching beacons received during scanning, should compare channel also in the compare. Since there is not channel differentiation in the SDL there is no need for this now.
7. Implement the procedure to test for lack of use of the GTS (i.e., 7.5.7.6 GTS expiration)
8. Implement a reallocation procedure for GTS on the coordinator side.
