As DDS implementations are typically based upon IP-based communication (mostly UDP/UP), there's no inherent limitation with running it over a wireless network.
I guess it depends on the DDS-vendor how configurable their networking is to accomodate for 'special' behavior that would be typical for wireless networks (such as undeterministic behavior when overloading the wireless network). As far as OpenSplice DDS is concerned, our networking-service is highly configurable w.r.t. specifying priority-lanes with configurable traffic-shaping (reactivity, bandwidth-limitation, automatic throttling, etc.) that would facilitate correct and efficient utilization of a wireless network.
