Abstract
This paper proposes a martingale extension of
effective-capacity, a concept which has been instrumental in
teletraffic theory to model the link-layer wireless channel and
analyze QoS metrics. Together with a recently developed concept
of an arrival-martingale, the proposed service-martingale concept
enables the queueing analysis of a bursty source sharing a MAC
channel. In particular, the paper derives the first rigorous and
accurate stochastic delay bounds for a Markovian source sharing
either an Aloha or CSMA/CA channel, and further considers
two extended scenarios accounting for 1) in-source scheduling
and 2) spatial multiplexing MIMO. By leveraging the powerful
martingale methodology, the obtained bounds are remarkably
tight and improve state-of-the-art bounds by several orders of
magnitude. Moreover, the obtained bounds indicate that MIMO
spatial multiplexing is subject to the fundamental power-of-two
phenomena.
