Opportunistic Scheduling with Power Control in Ad Hoc Wireless Networks

Abstract

To exploit the multiuser diversity in the CSMA/CA based wireless ad hoc networks, this paper proposes a new algorithm for opportunistic scheduling that will take advantage of both multiuser diversity and power control. The scheduling scheme is performed first before power control to further enhance throughput. The scheduling scheme ensures that the transmission is successful since a best candidate receiver is chosen for transmission and hence minimizes retransmissions. Likewise, the power control algorithm helps reduce interference between links and maximizes spatial reuse. In our study, we provided the scheduling scheme and the power control algorithm. We also showed optimal solutions for minimizing power consumption and maximizing net utility.
