Abstract
In this paper, we study joint end-to-end
congestion control and medium access control (MAC) in adhoc networks with fixed wireless channels as a utility
maximization problem with constraints that arise from
contention for channel access. Scheduling of the
transmissions is used, although random access can be used
too. We analyze the effects of clustering at both physical and
application level on the maximum end-to-end throughput
gained in the network. Our results show that the natural
clustering tendency of the users works favorably and can
improve network performance. Two types of network areas
are being considered: square shaped and rectangle shaped.
The rectangle shaped topology gave higher maximum end-toend throughput.
