Abstract--A key feature in the design of any MAC protocol is
the throughput it can provide. In wireless networks, the channel
of a user is not fixed but varies randomly. Thus, in order to
maximize the throughput of the MAC protocol at any given time,
only users with large channel gains should be allowed to transmit.
In this paper, a compressive sensing based compressive sensing
based opportunistic protocol for exploiting multiuser diversity
in wireless networks is proposed. This protocol is based on the
traditional protocol of R-ALOHA which allows users to compete
for channel access before reserving the channel to the best user.
We use compressive sensing to find the best user, and show that
