As evidenced by measurement data, channel fading and co-channel interference occur on the same time scales, and it is therefore difficult to determine if packet losses are due to interference change or channel variation. The coupling between the timescales of fading and interference at the MAC layer calls for a unified PHY/MAC design. Using optimal stopping theory, we first devise channel aware distributed...
In this paper, we consider contention-based ad-hoc networks, where links use mini-slots to contend for the channel (i.e., channel probing), and followed by data transmission over a longer duration, as in CSMA. We investigate channel-aware distributed scheduling under the multipacket reception (MPR) model, which involves a joint process of channel probing and distributed scheduling. In this study,...
