Abstract
A network broadcast method using a MAC unicast and an MPR node allows a source node to transmit a data packet to at least one MPR node which is located within one-hop distance from the source node and allows the at least one MPR node to transmit the data packet to each next-ranked MPR nodes. At least one normal node, which is not an MPR node while being located within one-hop distance from the source node, receives the data packet of the source node, which is transferred from the source node to an MPR node or transferred between MPR nodes through overhearing. Although the source node and MPR nodes are in a hidden-node relationship, collision is prevented, thereby minimizing data packet loss to improve the transmission reliability, and enabling the data packet of the source node to be reliably broadcasted on a network.
