Abstract
We address the problem of attaining proportionally fair rates using Aloha protocols at the medium access layer. We consider a wireless network where all nodes need not be in transmission ranges of each other. We show how the attempt probabilities in Aloha protocols should be set so that the achieved rates are globally proportionally fair. For both slotted and unslotted Aloha,we argue that each node can compute its optimal attempt probability just by knowing some minimal information about the network topology in its two-hop radius.
