Topology Aware Link Throughput of Slotted Aloha in Rayleigh Block Fading Channels

• In this work, we present an accurate analysis ofthe probability of successful transmission in a slotted Alohanetwork with an arbitrary topology, provided that the channelcan be accurately modeled as Rayleigh block fading channels.The obtained expression also takes into account the effect ofdifferent physical layer parameters such as modulation andcoding methods. However, its computational complexity growsquickly as the network size increases. To address this, wealso present an accurate approximation method in which theprobability of success for a link is predicted by considering onlya subset of the interfering nodes. A sufficient condition for theaccuracy of this prediction is also presented. The validity of theproposed methods are verified by a series of simulations.
