  We quantify the throughput capacity of wireless multi-hop networks with
several medium access schemes. We analyze pure ALOHA scheme where simultaneous
transmitters are dispatched according to a uniform Poisson distribution and
exclusion schemes where simultaneous transmitters are dispatched according to
an exclusion rule such as node coloring and carrier sense based schemes. We
consider both no-fading and standard Rayleigh fading channel models. Our
results show that, under no-fading, slotted ALOHA can achieve at least
one-third (or half under Rayleigh fading) of the throughput capacity of node
coloring scheme whereas carrier sense based scheme can achieve almost the same
throughput capacity as node coloring.
