無線ネットワークにおけるブロードキャスト方法およびその方法を使用した通信装置

Document Type and Number:

Japanese Patent JP3996930

Kind Code:

B2

Abstract:

A broadcast method in a wireless Personal Area 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.
