Abstract
Disclosed is a multicast system and a multicast method using a shortened address and an apparatus applied to the same. The multicast system using the shortened address according to the present disclosure has a address configuration for supporting a multicast in an IEEE 802.15.4 MAC (Medium Access Control) layer. Accordingly, when a device processes a multicast through an address configuration of the MAC layer, the device receives the multicast through a simple scheduling such as receiving a beacon signal of a coordinator device only when there is a broadcast of a group including the device. As a result, the device can efficiently perform the multicast in a power managing process or a power processing process.
