Name	Type	Description
ShortcutMac	simple module	This module implements a simple shortcut to peer MAC protocol that completely bypasses the physical layer. Packets received from the upper layer protocols are never lost. The MAC protocol directly sends packets to the destination MAC protocol without any physical layer processing. Physical layer overhead is simply simulated by overhead bits, overhead transmission duration and a propagation delay.
