A broadcast method in a wireless network and a communication apparatus using the same. The broadcast method determines whether the broadcast packet is first received upon receiving a broadcast packet. If a determination reveals that the packet is first received, the broadcast packet is stored and rebroadcast to neighbor nodes. Subsequently, a node, among the neighbor nodes, from which the broadcast packet is received, is marked as `relayed`. The broadcast packet is rebroadcast when all of the neighbor nodes from which the broadcast packet is received are not marked as `relayed`. When all of the neighbor nodes from which the broadcast packet is received are marked as `relayed`, the broadcast packet is destroyed. Accordingly, an efficient link-based broadcast method is provided.
