  In this paper, evolving wormholes in the context of brane-world scenario are
investigated. We have studied the possible dynamic solutions with different
forms of Ricci scalar. The possibility of existence of dynamic traversable
wormholes, without resorting to an exotic matter, has been studied. By using
the fact that the Einstein field equations are modified in 3+1 dimensions due
to the brane corrections, we investigate the exact solutions which satisfy null
energy condition. Asymptotic flatness is an important property of these
solutions. We discuss some physical and mathematical properties of the
solutions.
