Time is divided into non-overlapping slots when multi-hop wireless networks are accessed by TDMA mode. Side-length or fixed-length frames are transmitted in slots.
When facing a node, a node can get one or more slots, which can be used by the node to send messages to any link to its neighbors.
For link allocation, a one-way link is allocated one or more slots, in which message transmission is one-way.
