摘要： A system and method for selecting a starting point to transmit a beacon (BTSP) from a coordinator and a first node in a communication system. The communication system includes the coordinator, a first node group with at least one node having the first node which receives the beacon from the coordinator, and a second node group with at least one node having a second node which receives the beacon from the first node. The coordinator determines a beacon window size for the beacon transmission, selects the BTSP within the beacon window size, and transmits at the BTSP, the beacon containing information on the beacon window size and the BTSP. The first node selects its BTSP within the beacon window size so as not to overlap with the BTSP of the received beacon.

摘要： A route recovery method in a wireless network of a tree topology, in which a second node, which is a lower node of a first node and is disconnected from the first node, recovers the route in the network. The route recovery method includes the second node broadcasting a local repair request (LREQ) packet, each node receiving the LREQ packet sending a local repair reply (LREP) packet to the second node to act as a relay node for the route recovery, the second node selecting the relay node from among the nodes sending the LREP packet, and sending a local repair confirm (LCON) packet from the second node to the relay node, and establishing the route between the second node and the first node by the relay node sending a local repair inform (LINF) packet to the first node.

摘要： An apparatus and method thereof for route update for a communication system including a target, a sensor node collecting information of the target within a predetermined range, and a sink node receiving the information of the target from the sensor node through a first route built therebetween for target information transmission. The sensor node collects the information of the target, and broadcasts a routing request message when the information of the target is not received anymore. The information contained in the routing request message received from a first sensor node of a first sensor node on the first route is compared with the information contained in the routing request message received from a second sensor node of a second sensor node group at a predetermined distance from the first sensor node group. The first route is updated by using the sensor node selected based on the comparison.

摘要： A routing requesting method to transmit data to a device of a different piconets in a scatternet including at least two piconets which have a master device and at least one slave device controlled by the master device. A source device generates as a single packet an information inquiring a first radio resource used in each device of the piconet and an information requesting the routing. The source device broadcasts the packet to adjacent devices. The adjacent device, which receives the generated packet, sends the packet to a destination device by repeating the above process. The destination device assigns itself the master device, generates a RREP message including a clock information, and sends the generated RREP message to an adjacent device. The source device becomes aware of devices along the route using the information contained in the RREP message.

摘要： A routing method comprising receiving a first packet, the first packet being broadcast for discovery of a route. A first backoff of the first packet is calculated based on a route cost of the first packet. The first packet is rebroadcast if a second packet is not received within the first backoff, the second packet being a duplicate of the first packet. A second backoff of the second packet is calculated based on a route cost of the second packet if the second packet is received within the first backoff. One of the first and the second packets is rebroadcast as a result of comparing the first backoff and the second backoff.

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.
摘要翻译：无线网络中的广播方法和使用该方法的通信装置。广播方法确定广播分组是否在接收到广播分组时首先被接收。如果确定显示首先接收到分组，则广播分组被存储并重新广播到相邻节点。随后，从广播分组被接收的邻居节点中的节点被标记为“中继”。广播分组在接收到广播分组的所有邻居节点都没有被标记为“中继”时进行重播。当接收到广播分组的所有邻居节点被标记为“中继”时，广播分组被破坏。因此，提供了一种有效的基于链路的广播方法。
