Abstract
The present disclosure discloses a method and network device for overlaying one or more broadcast groups over virtual local area networks in a wireless network. The network device receives a broadcast/multicast message from a member device of a broadcast group. The broadcast group includes a subset of devices sharing at least one common property. The broadcast/multicast message is to be received by other member devices, but not by non-member devices of the first broadcast group. Furthermore, the broadcast group includes one of (i) a subset of devices from a single virtual local area network, and (ii) at least two subsets of devices from different virtual local area networks. The network device then determines the broadcast group associated with the received broadcast/multicast message based on the common property, and then transmits the received broadcast/multicast message to other member devices in the broadcast group.
