Design and Performance Evaluation of a Distributed OFDMA-Based MAC Protocol for MANETs
Figure 3
An example of operational procedure for a node to detect and treat an LET2. (In the following figures, we use frame time units. A circle represents the transmission range of a node located at the center of the circle. The solid arrows represent the intended direction of a frame and the dotted arrows represent the propagation of a frame to the nodes that are not the destinations of the frame. PDU denotes data sent through PDU bin .)
