Abstract
A wireless communication apparatus capable of constructing an ad-hoc wireless network is disclosed to include a transmitting/receiving unit configured to transmit and receive a common broadcast signal; and a transmission interval control unit configured to change transmission interval of the common broadcast signal to be transmitted depending on the number of communication nodes existing in communication range of the wireless communication apparatus or on the wireless resource utilization status.
Claims9
A wireless communication apparatus capable of structuring an ad-hoc wireless network, comprising:
- a transmitting/receiving unit configured to transmit and receive a common broadcast signal;
- a node counting unit configured to determine the number x of communication nodes existing in a communication range of the wireless communication apparatus, the communication nodes including the wireless communication apparatus;
- and
- a transmission interval control unit configured to adjust a transmission interval of the common broadcast signal to be transmitted depending on the number x of communication nodes determined by the node counting unit,
- wherein in response to the node counting unit detecting one additional communication nodes in the communication range and incrementing the number x of communication nodes by one, the transmission interval control unit is configured to adjust the transmission interval to be equal to a product of a predefined initial transmission interval and (x+1).
A wireless communication system applicable to an ad-hoc wireless network, the system including:
- two or more wireless communication apparatuses capable of structuring the ad-hoc wireless network,
- wherein each of the wireless communication apparatuses comprises:
- a transmitting/receiving unit configured to transmit and receive a common broadcast signal;
- a node counting unit configured to determine the number x of communication nodes existing in a communication range of the wireless communication apparatus, the communication nodes including the wireless communication apparatus;
- and
- a transmission interval control unit configured to adjust a transmission interval of the common broadcast signal to be transmitted depending on the number x of communication nodes determined by the node counting unit,
- wherein in response to the node counting unit detecting one additional communication nodes in the communication range and incrementing the number x of communication nodes by one, the transmission interval control unit is configured to adjust the transmission interval to be equal to a product of a predefined initial transmission interval and (x+1).
