Broadcasting, and scanning for wireless communication

A device, comprising:

• a memory that stores executable modules;
• and
• a processor, coupled to the memory, that executes the executable modules to perform operations of the apparatus, the executable modules comprising:
• a broadcasting and listening module configured to send a broadcasting packet by using a current power and listening;
• a power decreasing module configured to, in response to the broadcasting and listening module detecting a request via the listening, record the current power as a historical power, and decrease the current power;
• and
• a power determining module configured to determine whether a current broadcasting event has ended, and in response to the current broadcasting event being determined to have ended, determine the historical power as a reference working power.

A computer readable storage device, comprising at least one executable instruction, which, in response to execution, causes a device comprising a processor to perform operations, comprising:

• sending a broadcasting packet by using a current power and listening;
• when a request is detected by means of listening, recording the current power as a historical power, and decreasing the current power;
• and
• determining whether a current broadcasting event has ended, and if the current broadcasting event has ended, determining the historical power as a reference working power, and otherwise, returning to the sending.

A device, comprising a processor and a memory, the memory storing executable instructions, the processor being connected to the memory through a communication bus, and when the broadcasting device for wireless communications operates, the processor executes the executable instructions stored in the memory, causing the device to perform operations, comprising:

• sending a broadcasting packet by using a current power and listening;
• when a request is detected by way of the listening, recording the current power as a historical power, and decreasing the current power;
• and
• determining whether a current broadcasting event has ended, in response to the current broadcasting event being determined to have ended, determining the historical power as a reference working power, and otherwise, returning to the sending.
