In this work we find cosmological solutions in the brane-bulk system starting from a 5D line element which is a simple extension, for cosmological applications, of the pioneering Randall-Sundrum line element. From the knowledge of the bulk metric, assumed to have the form of plane waves propagating in the fifth dimension, we solve the corresponding 4D Einstein equations on the brane with a well defined energy-momentum tensor.
