Abstract

A wireless communication device includes: a communication portion that periodically transmits management information for forming a wireless network with at least one wireless communication device, a determination portion that determines, based on one of an attribute and a supply speed of information supplied from a given device, whether to add the information to the management information, and a generation portion that adds the information to the management information according to a determination result of the determination portion.

Claims

1. A wireless communication device, comprising:

a communication portion that periodically transmits management information for forming a wireless network with at least one wireless communication device;

a determination portion that determines, based on one of an attribute and a supply speed of information supplied from a given device, whether to add the information to the management information; and

a generation portion that adds the information to the management information according to a determination result of the determination portion.

2. The wireless communication device according to claim 1,

wherein the determination portion determines to add the information supplied from the given device to the management information in a case where the supply speed is less than a specified speed.

3. The wireless communication device according to claim 2,

wherein the generation portion writes the address of a specific wireless communication device in the information supplied from the given device.

4. The wireless communication device according to claim 3,

wherein the generation portion discretely adds an error-detection code of the management information and an error-detection code of the information supplied from the given device.

5. The wireless communication device according to claim 4,

wherein the communication portion receives from the specific wireless communication device the management information indicating whether correct reception was performed by the specific wireless communication device;

and

in a case where the management information received from the specific wireless communication device by the communication portion indicates that correct reception by the specific wireless communication device was not performed, the generation portion again adds already-sent information supplied from the given device to the management information.

6. The wireless communication device according to claim 2,

wherein a unit period, including a first period and a second period in which the management information is transmitted by the communication portion, is periodically repeated;

and

the communication portion transmits, in the first period, the information supplied from the given device, in a unit period in which the communication portion does not transmit the management information in the second period.

7. The wireless communication device according to claim 2,

wherein a unit period, including a first period and a second period in which the management information is transmitted by the communication portion, is periodically repeated;

and

in a case where the communication portion does not transmit the management information in the second period in a specific unit period, the communication portion transmits the management information to which the information supplied from the given device has been added, in the second period in the unit period following the specific unit period.

8. The wireless communication device according to claim 3, further comprising:

a management portion that manages whether the specific wireless communication device is in an operating state or a hibernating state based on the management information received from the specific wireless communication device by the communication portion;

wherein

the communication portion transmits, in a period in which the specific wireless communication device is in an operating state, the management information to which the information supplied from the given device has been added.

9. The wireless communication device according to claim 1,

wherein the determination portion determines to add the information supplied from the given device to the management information in a case where an attribute of the information is one of text information, voice information, and audio information.

10. A wireless communication method, comprising the steps of:

periodically transmitting management information for forming a wireless network with at least one wireless communication device;

determining, based on one of an attribute and a supply speed of information supplied from a given device, whether to add the information to the management information; and

adding the information to the management information according to a result of the determination.

11. A program that comprises instructions that command a computer to function as:

a communication portion that periodically transmits management information for forming a wireless network with at least one wireless communication device;

a determination portion that determines, based on one of an attribute and a supply speed of information supplied from a given device, whether to add the information to the management information; and

a generation portion that adds the information to the management information according to a determination result of the determination portion.

12. A wireless communication system, comprising

a plurality of wireless communication devices each having:

a communication portion that periodically transmits management information for forming a wireless network with at least one wireless communication device;

a determination portion that determines, based on one of an attribute and a supply speed of information supplied from a given device, whether to add the information to the management information; and

a generation portion that adds the information to the management information according to a determination result of the determination portion.
