1. A system for setting an ad-hoc network in a transmitting terminal, the system comprising:

  • a storage unit for storing a critical value of acceleration of the terminal;

    an acceleration sensor for measuring the acceleration of the terminal and for providing a value of the measured acceleration; and

    a transmission frame processor for determining whether the value of the acceleration measured by the acceleration sensor exceeds a critical value of acceleration stored in the storage unit,wherein, if it is determined that the value of the measured acceleration does not exceed the critical value of acceleration stored in the storage unit, the transmission frame processor adds the value of the measured acceleration to an acceleration information field of a Media Access Control (MAC) frame and broadcasts the MAC frame to surrounding receiving terminals, andwherein the transmission frame processor does not broadcast any MAC frame if it is determined that the value of the acceleration measured by the acceleration sensor exceeds the critical value of acceleration stored in the storage unit.
