Abstract

A wireless communication device in a wireless network sets management information notification cycles at specified time intervals and transmits management information containing receive timing information showing its own position to start receiving information, receive window information, and receive cycle information. Another wireless communication device receiving that management information links it to a communication device number for the corresponding wireless communication device and stores the receive timing, the receive window information, and the receive cycle information. When sending information, the receive start position of the corresponding communication device is found from the receive timing information, the receive window information, and the receive cycle information of the other communication and information is then transmitted at that timing. An asynchronous ad-hoc communication wireless network can therefore be configured without a particular control station.

Claims

1. A destination device that wirelessly receives data from a source device, the destination device comprising:

circuitry configured to broadcast management information including duration information and device identification information of the destination device, the duration information specifying duration when the destination device is capable of receiving data as distinguished from timings during which the destination device is incapable of receiving the data, and the duration information including a start receiving timing information that indicates a timing position to start receiving the data, a receive window information that indicates a length of time for performing receive processing of the data, and a receive window cycle information that indicates where a next window for reception is provided; and

circuitry configured to directly receive data from the source device in the duration when the destination device is capable of receiving the data,

wherein the duration information is set by the destination device to define notification cycles for broadcasting the management information.

2. A method of wirelessly receiving data from a source device, the method comprising:

broadcasting, from a destination device, management information including duration information and device identification information of the destination device, the duration information specifying duration when the destination device is capable of receiving data as distinguished from timings during which the destination device is incapable of receiving the data, and the duration information including a start receiving timing information that indicates a timing position to start receiving the data, a receive window information that indicates a length of time for performing receive processing of the data, and a receive window cycle information that indicates where a next window for reception is provided, and

directly receiving data from the source device in the duration when the destination device is capable of receiving the data,

wherein the duration information is set by the destination device to define notification cycles for broadcasting the management information.

3. A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:

broadcasting, from a destination device, management information including duration information and device identification information of the destination device, the duration information specifying duration when the destination device is capable of receiving data as distinguished from timings during which the destination device is incapable of receiving the data, and the duration information including a start receiving timing information that indicates a timing position to start receiving the data, a receive window information that indicates a length of time for performing receive processing of the data, and a receive window cycle information that indicates where a next window for reception is provided, and

directly receiving data wirelessly from a source device in the duration when the destination device is capable of receiving the data,

wherein the duration information is set by the destination device to define notification cycles for broadcasting the management information.
