Method and device for route searching in a bluetooth ad-hoc network
First Claim
1. A method for transmitting a route request for a route between a source node and a destination node in an ad-hoc network and for transmitting a reply identifying the route, the ad-hoc network including a plurality of nodes including at least one master node in at least one piconet, said method comprising:
- transmitting the route request from the receiving node in the ad-hoc network to the at least one master node of said at least one piconet via a unicast transmission; and
generating a route reply and sending the route reply to the source node, the route reply identifying the route in the ad-hoc network between the source node and the destination node.

Abstract
A method for transmitting a route request in an ad-hoc network having master nodes and slave nodes includes transmitting the route request to the master nodes of the network via a unicast transmission and transmitting a reply identifying the route. Each node of the network which receives the request performs a route request algorithm. The algorithm may be implemented in the network layer of the device protocol stack or in the link layer of the device protocol stack.

- 14. A device-readable memory for a communication device, the memory storing device-readable instructions for transmitting a route request in an ad-hoc network and for generating a route reply identifying the route, the route request being one of received at and generated by the communication device for a route between a source node and a destination node in the ad-hoc network, the ad-hoc network including a plurality of nodes including the communication device and at least one master node in at least one piconet, said memory comprising device-readable instructions for transmitting the route request from the communication device in the ad-hoc network to the at least one master node of the at least one piconet via a unicast transmission and for generating a route reply and sending the route reply to the source node, the route reply identifying the route in the ad-hoc network between the source node and the destination node.
- 23. A wireless communication device for transmitting a route request for a route between a source node and a destination node in an ad-hoc network and for generating a route reply identifying the route, the route request being one of received at and generated by the device, wherein the ad-hoc network includes a plurality of nodes including the device and at least one master node in at least one piconet, said device comprising a transceiver and a memory storing device-executable instructions for transmitting the route request to the at least one master node of the at least one piconet via a unicast transmission and for generating a route reply and sending the route reply to the source node, the route reply identifying the route in the ad-hoc network between the source node and the destination node.
