Synchronization control method within wireless network, wireless network and smart home device

A wireless network, comprising at least one control terminal and N smart home devices, N being an integer greater than 1, wherein the smart home device comprises:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• receive a control command directed at multiple smart home devices, wherein the control command carries a count-down time duration for command execution time;
• broadcast the control command received by the smart home device within a wireless broadcast coverage area of the smart home device, wherein the broadcasted control command carries processing time for the smart home device to process the control command as well as a total processing time for forwarding the control command previously;
• determine whether the smart home device needs to execute the control command received by the smart home device;
• when it is determined that the control command is to be executed, determine the command execution time according to the count-down time duration in the received control command, as well as the total processing time of respective smart home devices which the control command passes on its transmission path.

A smart home device, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to:
• receive a control command directed at multiple smart home devices, wherein the control command carries a count-down time duration for command execution time;
• continue to broadcast the control command received by the smart home device within wireless broadcast coverage area of the smart home device, wherein the broadcasted control command carries the processing time for the smart home device to process the control command as well as a sum of processing time for forwarding the control command previously;
• determine whether the smart home device needs to execute the control command received by the smart home device;
• when it is determined that the control command is to be executed, determining command execution time according to the count-down time duration in the received control command, as well as the total processing time of respective smart home devices which the control command passes on its transmission path.
