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 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： 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 method of detecting and solving a network ID conflict is provided. The method of detecting and solving a network ID conflict includes generating and transmitting a personal area network identifier (PAN ID) report command frame that includes an extended PAN ID, and receiving a PAN ID update command frame in response to the transmitted PAN ID report command frame. According to the method, the PAN ID report command and the PAN ID update command are generated and provided by providing an extended PAN ID (EPID), and thus a network ID conflict can be detected and a new PAN ID is provided to solve the network ID conflict.
