Abstract: PURPOSE: A network broadcast method using an MAC(Medium Access Control) unicast and a relay node is provided to minimize the loss of a data packet by preventing collision between an MPR(MultiPoint Relay) node and a source node. CONSTITUTION: A source node transmits a data packet to one or more first MPR nodes using an MAC unicast method. One or more first MPR nodes transmit the data packet to a second MPR node using the MAC unicast method. When one or more second MPR nodes are not existed within a first hop, one or more first MPR nodes transmit the data packet to a normal node using the MAC unicast method.
