We study channel aware distributed scheduling in ad hoc networks where many links contend for the common channel using random access, and the focus here is on the model where each transmitter node has multiple intended receivers. In such a network, channel probing takes place in two phases: 1) in phase I, all transmitters contend for the channel using random access to reserve the channel, and the...
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...
