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...
The conventional function of the medium access control (MAC) layer in wireless networks is interference management. We show how the MAC can also be used to mitigate the effect of fading. We begin by providing experimental data to demonstrate that multipath fading effects are seen at the MAC layer. These effects appear at timescales on the same order of the IEEE 802.11 protocol and therefore, interact...
