ABSTRACT

In multiaccess wireless networks where a common channel is shared by a population of users, both the reception capability of the common wireless channel and the efficiency of the medium access control (MAC) protocol affect the network performance. Traditionally, MAC protocols are designed based on a collision channel model where any concurrent transmissions result in the destruction of all transmitted packets.

Numerous protocols, such as ALOHA, the tree algorithm, the first-come first-serve (FCFS) algorithm [5], and a class of adaptive schemes [6, 14, 15, 17], have been proposed to coordinate the transmissions of all users for the efficient utilization of the limited channel reception capability.
