  We propose a W state-based protocol for anonymously transmitting quantum
messages in a quantum network. Different from the existing protocols [A.
Unnikrishnan, et al., Phys. Rev. Lett. 122, 240501 (2019)], the proposed
protocol can be effectively implemented in the network only equipped with
quantum channels and regular broadcast channels. Throughout the design
procedure, we develop three sub-protocols using the W state, including the
quantum collision detection protocol and the quantum notification protocol.
Moreover, together with the conventional anonymous entanglement protocol, the
whole anonymous communication protocol has been constructed. Finally, we
examine the correctness and security of the proposed quantum anonymous
communication protocol.
