The problem of optimizing the medium access probability in a multipacket-reception-capable network, when only inaccurate estimates of the offered traffic are known, is addressed. It is shown that a larger uncertainty in the traffic estimates must be compensated by a more conservative access policy. The analysis is verified by examples and simulation results.
Medium access in ad-hoc wireless networks must be performed in a distributed fashion due to lack of coordination between nodes. Specifically, when nodes are capable of receiving more than one transmission simultaneously, the design of distributed medium-access mechanisms that efficiently exploit the receiver's capability becomes more challenging. Adaptive probabilistic medium access for ad-hoc wireless...
