  We present a minimal framework of $U(1)_{B-L}$ gauge extension of the
Standard Model explaining dark matter abundance and matter-antimatter asymmetry
simultaneously through an attractive mechanism of TeV scale WIMPy leptogenesis,
testable at the current and next generation of colliders. This framework can
also explain small neutrino masses via a radiative mechanism. One of the key
predictions of this model is an enhanced rate for lepton flavor violating decay
$\mu \rightarrow e \gamma$ within the sensitivity reach of next generation
experiments.
