在多跳无线网络进行TDMA方式接入时候，时间是被划分为互不重叠的时隙，边长或定长帧在时隙中进行传输。
当面向节点时候，一个节点可以得到一个或者多个时隙，节点可以利用这些时隙向任何一条链路发送报文到邻居节点。
面向链路分配时候，则是某条单向链路分得一个或多个时隙，在这些时隙中，报文发送是单向的。(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.)
