Routing system and method in scatternet
First Claim
1. A routing request method of a scatternet including at least a first piconet and a second piconet, to transmit data to a device of the second piconet, each of the first and second piconets having a master device and at least one slave device controlled by the master device, comprising:
- generating a single packet having information inquiring about a first radio resource used in each of a plurality of devices of the first piconet and an information requesting a route, as a generated packet; and
broadcasting the generated packet to adjacent devices of the plurality of devices.

Abstract
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.

7. A routing response method of a scatternet including at least a first piconet and a second piconet, to reply to a routing request from a first device of the first piconet, each of the first and the second piconets having a master device and at least one slave device controlled by the master device, comprising:
-
assigning a second device receiving the routing request as a first master device or as a first slave device, and generating a route reply (RREP) message as a generated RREP including a clock information; and
sending the generated RREP message to a first adjacent device adjacent to the second device. - View Dependent Claims (8, 9, 10)

11. A routing system of a scatternet including at least a first piconet and a second piconet, for requesting a route to transmit data to a device of the second piconet, each of the first and second piconets having a master device and at least one slave device controlled by the master device, comprising:
-
a source device generating and broadcasting a single packet as a generated broadcast packet having an information inquiring about a first radio resource used in each of a plurality of devices of the first piconet and an information requesting a routing; and
at least one adjacent device receiving the broadcast packet from the source device. - View Dependent Claims (12, 13, 14, 15, 16)

17. A routing system of a scatternet including at least a first piconet and a second piconet, for responding to a routing request from a device of the first piconet in a communication system, each of the at least first and second piconets having a master device and at least one slave device controlled by the master device, comprising:
-
a destination device assigning a device receiving the routing request as a first master device or a first slave device, and generating a route reply (RREP) message as a generated RREP including a clock information; and
a first adjacent device adjacent to the destination device receiving the generated RREP message from the destination device. - View Dependent Claims (18, 19, 20)
