A global positioning system using Bluetooth technology, including: a first Bluetooth master that receives satellite orbit information; a Bluetooth slave that communicates with the first Bluetooth master in a Bluetooth protocol; and a second Bluetooth master that transmits an inquiry code for communication with the Bluetooth slave in the Bluetooth protocol. The second Bluetooth master provides positioning information by requesting the satellite orbit information from the first Bluetooth master through the Bluetooth slave and transmitting the satellite orbit information to the second Bluetooth master through the Bluetooth slave.

Driving method of global positioning system using short-range communication

A routing method in consideration of the power and transmission delay in a wireless ad hoc network and a terminal device adopting the same are provided, which can reduce the power consumption and packet delay by considering both the power consumption and packet delay. The terminal device includes a judgment unit that determines whether a first accumulative hop count included in a first route request (RREQ) packet exceeds a predetermined route decision value for limiting a hop count from a source node to a destination node, and a control unit that determines a route to the source node, based on information included in the first RREQ packet, if the judgment unit determines that the first accumulative hop count does not exceed the route decision value.
