Abstract
An anti-collision method and system in a wireless network system are provided. The anti-collision method includes: transmitting a beacon signal including information related to an owner type of a first device and information related to an available time interval of the first device; transmitting information related to a time interval selected from the available time interval to a second device having receiving the beacon signal from the first device; and updating the information related to the available time interval using information related to the selected time interval. The information related to the owner type of the first device includes information indicating one of a unicast device and a multicast device.
Claims14
An anti-collision method in a wireless network system, comprising:
- transmitting, by a first device, a first beacon signal comprising information related to a type of a first device and information related to a first available time interval of the first device, the information related to the first available time interval of the first device being different based on the information related to the type of the first device;
- a second device receiving information related to a time interval selected from the first available time interval, the second device having received the first beacon signal from the first device;
- and
- updating the information related to the first available time interval using information related to the selected time interval,
- wherein the information related to the type of the first device comprises information indicating one of a unicast device and a multicast device.

An anti-collision method in a wireless network system, comprising:
- transmitting, by a first device, a beacon signal comprising a multicast-specific DRP IE (distributed reservation protocol information element) comprising information related to a type of a first device and a multicast-specific DRP availability IE comprising information related to an available time interval of the first device, the information related to the available time interval of the first device being different based on the information related to the type of the first device;
- a second device receiving information related to a time interval selected from the available time interval, the second device having received the beacon signal from the first device;
- and
- updating the information related to the available time interval using information related to the selected time interval,
- wherein the information related to the type of the first device comprises information indicating one of a unicast device and a multicast device.
2 more elements
A device comprising:
- a transceiver which transmits a first beacon signal comprising information related to a type of the device and information related to an available time interval of the device and receives information related to a time interval selected from the available time interval by an external device having received the first beacon signal, the information related to the available time interval of the device being different based on the information related to the type of the device;
- and
- a time interval manager updating the information related to the available time interval through information related to the selected interval,
- wherein the information related to the type of the device comprises information indicating one of a unicast device and a multicast device.
1 more element
A device comprising:
- a transceiver transmitting a beacon signal comprising a multicast-specific distributed reservation protocol information element (DRP IE) comprising information related to a type of the device and a multicast-specific DRP availability IE comprising information related to an available time interval of the device and receiving information related to a time interval selected from the available time interval by an external device having received the beacon signal, the information related to the available time interval of the device being different based on the information related to the type of the device;
- and
- a time interval manager updating the information related to the available time interval using information related to the selected interval,
- wherein the information related to the type of the device comprises information indicating one of a unicast device and a multicast device.
1 more element
A wireless network system comprising:
- a first device transmitting a beacon signal comprising information related to a type of the first device and information related to a first available time interval, the information related to the first available time interval being different based on the information related the type of the first device;
- and
- a second device receiving the beacon signal from the first device to transmit information related to a time interval selected from the first available time interval,
- wherein the first device updates the information related to the first available time interval using the information related to the selected time interval, and
- wherein the information related to the type of the first device comprises information indicating one of a unicast device and a multicast device.
