Abstract

Disclosed are a method for media access controlling and channel time reservation system and method in distributed wireless personal area networks. A method of media access controlling for a distributed wireless network including at least one device, includes a device of the distributed wireless network, generating a data slot reservation indicator for devices of the same beacon group, and the device, broadcasting the generated data slot reservation indicator. Thus, a slot reservation for communication between devices can be completed in a shorter period of time. Also, capacity of the network can be improved by spatial reuse of channel time.

Claims

1. A method of media access controlling for a distributed wireless network including at least one device, the method comprising:

a device of the distributed wireless network, generating a data slot reservation indicator for devices of the same beacon group; and

the device, broadcasting the generated data slot reservation indicator.

2. The method as claimed in claim 1, wherein the data slot reservation indicator comprises a reservation status information regarding data slots of a super frame of the beacon group to which the one device belongs.

3. The method as claimed in claim 2, wherein the super frame comprises 256 data slots, and the reservation status information indicates whether the 256 data slots are available for reservation or not.

4. The method as claimed in claim 2, wherein the reservation status information of one data slot is expressed using ‘

1’

one bit,

the reservation status information for the data slots available for reservation by the devices of the beacon group is expressed as ‘

1’

, and

the reservation status information for the data slots unavailable for reservation by the devices of the beacon group is expressed as ‘

0’

.

5. The method as claimed in claim 1, wherein the data slot reservation indicator further comprises an ID information of the data slot reservation indicator, and a length information about the reservation status information of the data slots of the super frame.

6. The method as claimed in claim 5, wherein the data slot reservation indicator information comprises 1 byte of the ID information, and 1 byte of the length information.

7. The method as claimed in claim 1, wherein the data slot reservation indicator includes an information indicating the data slots available for reservation by the devices of the beacon group.

8. The method as claimed in claim 1, wherein the data slot reservation indicator includes an information indicating the data slots unavailable for reservation by the devices of the beacon group.

9. A method of media access controlling in a distributed wireless network including at least one device, the method comprising:

a device of the distributed wireless network, broadcasting a data slot reservation indicator of the devices of the same beacon group.

10. A method of media access controlling in a distributed wireless network including at least one device, the method comprising:

all devices of the distributed wireless network, generating a data slot reservation indicator of the devices of the same beacon group; and

the all devices, broadcasting the generated data slot reservation indicator simultaneously.
