Abstract
A wireless device and method for managing a multicast group within a wireless network are disclosed. The wireless device is included in a first multicast group in which data is directly sent between member devices or data is sent using hopping between the member devices. The wireless device includes a reception unit, a determination unit, and a transmission unit. The reception unit receives a join request for joining a second multicast group from a joining device that attempts to join the second multicast group. The determination unit extracts information about the second multicast group from the join request, and determines whether the second multicast group is identical with the first multicast group based on the information about the second multicast group. The transmission unit forwards the join request to another device or sends a response to the join request to the joining device based on a result of the determination.
