Topology Aware Link Throughput of Slotted Aloha in Rayleigh Block Fading Channels
Paper in proceedings, 2010
In this work, we present an accurate analysis of
the probability of successful transmission in a slotted Aloha
network with an arbitrary topology, provided that the channel
can be accurately modeled as Rayleigh block fading channels.
The obtained expression also takes into account the effect of
different physical layer parameters such as modulation and
coding methods. However, its computational complexity grows
quickly as the network size increases. To address this, we
also present an accurate approximation method in which the
probability of success for a link is predicted by considering only
a subset of the interfering nodes. A sufficient condition for the
accuracy of this prediction is also presented. The validity of the
proposed methods are verified by a series of simulations.
