From draft-ietf-dnssd-requirements-03:

6.5.  Privacy Considerations

   Mobile devices such as smart phones that can expose the location of
   their owners by registering services in arbitrary zones pose a risk
   to privacy.  Such devices must not register their services in
   arbitrary zones without the approval ("opt-in") of their users.
   However, it should be possible to configure one or more "safe" zones
   in which mobile devices may automatically register their services.

There's no way to do this securely if you don't have a way to authenticate the network.   sedhcp or SeND would be obvious ways to do this.   SeND would probably be preferable, but sedhcp would work and may be easier to actually get working in practice.
