Power Controlled Multiple Access Control for Wireless Access Nets

In this paper, we develop and investigate a new joint power controlled medium access control (MAC) algorithm for wireless access nets (ANets). In an ANet, the user nodes are associated with a single central node (backbone node) that serves to allocate and manage their resources. Under our new protocol, the net backbone node (BN) instructs the ANet nodes to make power control adjustments while simultaneously allocating to them slots for the requested transmissions of their packets. Our algorithm leads to significant increase in the net throughput level by attaining high spatial reuse while striving to reduce power consumption in that nodes only employ the power levels required to reach their designated destinations. By introducing fair queuing and scheduling elements, we demonstrate the ability of our algorithm to support fairness in our scheduling. Two different methodologies for incorporation of fairness are proposed. We demonstrate the throughout and delay vs. fairness trade-off behavior of our new protocol.
