  Relic abundance of asymmetric Dark Matter particles in brane world
cosmological scenario is investigated in this article. Hubble expansion rate is
enhanced in brane world cosmology and it affects the relic abundance of
asymmetric Dark Matter particles. We analyze how the relic abundance of
asymmetric Dark Matter is changed in this model. We show that in such kind of
nonstandard cosmological scenario, indirect detection of asymmetric Dark Matter
is possible if the cross section is small enough which let the anti--particle
abundance kept in the same amount with the particle. We show the indirect
detection signal constraints can be used to such model only when the cross
section and the 5 dimensional Planck mass scale are in appropriate values.
