The thin-shell wormhole created using the Darmois-Israel formalism applied toRobinson-Trautman family of spacetimes is presented. The stress energy tensorcreated on the throat is interpreted in terms of two dust streams and it isshown that asymptotically this wormhole settles to the Schwarzschild wormholewith a throat located at the horizon position. This behavior shows a nonlinearstability (within the Robinson-Trautman class) of this spherically symmetricwormhole. The gravitational radiation emitted by the Robinson-Trautman wormholeduring the transition to spherical symmetry is indistinguishable from that ofthe corresponding black hole Robinson-Trautman spacetime. Subsequently, we showthat the higher-dimensional generalization of Robinson-Trautman geometry offersa possibility of constructing wormholes without the need to violate the energyconditions for matter induced on the throat.
