Abstract

A system and method for wireless communication by a plurality of devices in a scatternet network is provided. The method includes discovering one or more of the plurality of devices in the scatternet network. The method includes determining roles for one or more of the plurality of devices, and transferring data between one or more of the plurality of devices. The discovering of other devices, determining roles, and transferring data between one or more of the plurality of devices occur substantially simultaneously.

Claims

1. A method for wireless communication by a plurality of devices in a scatternet network, comprising:

discovering one or more of the plurality of devices in the scatternet network;

determining roles for one or more of the plurality of devices; and

transferring data between one or more of the plurality of devices, such that the discovering of other devices, determining roles, and transferring data between one or more of the plurality of devices occur substantially simultaneously.

2. The method of claim 1, wherein the discovering is further defined as a first device discovering at least a second device of the plurality of devices, wherein the determining is further defined as the first device determining roles as between the first device and the second device, and wherein the first and second device transfer data, such that the discovery, roles determination, and data transfer between the first and second device occur substantially simultaneously.

3. The method of claim 1, wherein the plurality of devices are selected from a group consisting of mobile communication devices, mobile phones, personal digital assistants, laptop computers, tablet computers, wireless access points, desktop computers, and personal computers.

4. The method of claim 1, wherein the plurality of wireless devices wirelessly communicate via Bluetooth.

5. The method of claim 1, further comprising transmitting hop information between the plurality of network devices.

6. The method of claim 5, wherein only information related to a topology of the scatternet network is delayed.

7. The method of claim 1, further comprising:

requesting a connection between the plurality of devices;

deciding on a decision maker as between the plurality of devices; and

deciding whether to maintain a connection.

8. The method of claim 7, further comprising:

deciding to disconnect;

requesting to disconnect; and

terminating the connection between the plurality of devices.

9. A system for communication in a scatternet, comprising:

a wireless device having a processor programmed to discover at least one other wireless device in the scatternet network, the processor programmed to determine roles as between the wireless device and the other wireless device and transfer data between the wireless device and the other wireless device, such that the discovery of the other wireless device, determining the roles, and transferring data between the wireless device and the other wireless device occurs at substantially the same time.

10. The system of claim 9, wherein the wireless device is selected from a group consisting of mobile communication devices, mobile phones, personal digital assistants, laptop computers, tablet computers, wireless access points, desktop computers, and personal computers.

11. The system of claim 9, wherein the wireless device communicates via Bluetooth.

12. The system of claim 9, further comprising transmitting hop information between the wireless device and the other wireless device.

13. The system of claim 12, wherein only information related to a topology of the scatternet network is not transmitted at substantially the same time as the discovery, roles determination, and data transfer.

14. A system for communication in a scatternet network, comprising:

a first wireless device; and

a second wireless device, the first wireless device communicates to discover the second wireless device, the first and second wireless devices determine roles, and the first and second wireless devices transfer data between one another, such that the discovery, roles determination, and data transfer between the first and second devices occurring at substantially the same time.

15. The system of claim 14, wherein the first and second devices are selected from a group consisting of mobile communication devices, mobile phones, personal digital assistants, laptop computers, tablet computers, wireless access points, desktop computers, and personal computers.

16. The system of claim 14, wherein the first and second wireless devices communicate via Bluetooth.

17. The system of claim 14, further comprising transmitting hop information between the first and second wireless devices, and wherein only information related to a topology of the scatternet network is delayed.

18. The system of claim 14, further comprising:

the first wireless device requesting a connection with the second wireless device;

wherein the first and second devices decide on a decision maker as between the first and second devices; and

deciding whether to maintain a connection.

19. The system of claim 18, further comprising:

when the first device decides to disconnect, the first device requests to disconnect from the second device and the second device sends a confirmation.

20. The system of claim 14, wherein only information related to a topology of the scatternet network is not transmitted at substantially the same time as the discovery, roles determination, and data transfer.
