1. Channel Partitioning
* divide channel into smaller "pieces"(time slots,
frequency, code)
* allocate piece to node for exclusive use
2. Random Access
* channel not divided, allow collisions
(channel 不切割，同意碰撞)
* "recover" from collisions
(從碰撞去復原資料)
3. "Taking turns"(輪流)
* Nodes take turns, but nodes with more to send can take
longer turns
