    摘要： A method for packet re-flooding in a wireless ad hoc network for transmitting a broadcast packet from a source node to a destination node. In order to determine the respective nodes received with the broadcast packet from the source node into a certain number of power levels in accordance with the receiving power of the signal carrying the received packet, the packet re-flooding method includes the steps of setting a power level reference by which the power level increases as the receiving power increases, obtaining the receiving power of the signal carrying the packet received from the respective nodes but not the source node, determining power levels based on the power level reference and the obtained receiving power, calculating a back-off delay time in accordance with the power levels of the respective nodes but not the source node, and re-flooding the received packet when the calculated back-off delay time of the respective nodes excluding the source node expires and when the received packet is the first packet that is received. Accordingly, the possibility of having collisions due to re-flooding of the respective nodes is reduced, and also, overall power consumption of the network decreases.

    摘要： 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.

    摘要： A method to manage nodes in a ZigBee network. In a ZigBee network including a plurality of nodes, a multicast group is generated including at least two nodes among the plurality of the nodes. A multicast group coordinator (GC) which manages the multicast group is set among the nodes forming the multicast group. The multicast group includes the GC, a multicast group member (GM) requesting to join the multicast group, and/or a multicast router (MR) which links GMs to each other or links the GC and the GC. Accordingly, since the GC manages the multicast group, the load is decreased and the packet data transmission rate is enhanced.

    摘要： A method for relaying a route request RREQ message by an intermediate node which is connected with at least one node using a tree topology in a mobile communication system including a destination node and a source node which sends the RREQ message to the destination node via at least one intermediate node, to thus establish an optimal route for communications. The RREQ message is received along the route other than the tree route, and the first information is updated using its information. The intermediate node relays to a next intermediate node the RREQ message containing the updated first information.
