In this paper, the authors present a scheme, called the Virtual Backoff Algorithm (VBA), which is based on the sequencing technique for efficient medium-access control. The proposed method minimizes the number of collisions while reducing the delays that occur during the backoff periods. They present an analytical study on MAC-layer issues, which are very important when accessing a channel over wireless networks. The VBA scheme uses fair distributed mechanisms to access a channel. They introduce a counter at each node to maintain the discipline of the nodes.
