Abstract

A method of reducing power consumption of a receiver includes identifying a plurality of sensors for transmitting a signal, generating data for controlling a transmission operation of the plurality of sensors, and transmitting the data to the plurality of sensors.

Claims

1. A method of reducing power consumption of a receiver, the method comprising:

identifying a plurality of sensors configured to transmit a signal;

generating data to control a transmission operation of the plurality of sensors; and

transmitting the data to the plurality of sensors.

2. The method of claim 1, wherein the generating of the data to control the transmission operation of the plurality of sensors identified comprises generating data to control the transmission operation of the plurality of sensors based on either one or both of a number of the plurality of sensors and identification information of the plurality of sensors.

3. The method of claim 1, wherein the generating of the data to control the transmission operation of the plurality of sensors identified comprises generating data to adjust a transmission time of the plurality of sensors.

4. The method of claim 1, wherein the generating of the data to control the transmission operation of the plurality of sensors identified comprises generating data to adjust the transmission operation for a signal to be transmitted by the plurality of sensors at predetermined intervals.

5. The method of claim 1, wherein the data comprises time information indicating a period of time required to elapse before a sensor is permitted to transmit a signal subsequent to the sensor receiving the data.

6. The method of claim 1, wherein the generating of the data to control the transmission operation of the plurality of sensors identified comprises generating data to adjust a communication frequency of the plurality of sensors.

7. The method of claim 1, wherein the generating of the data to control the transmission operation of the plurality of sensors identified comprises generating data to assign different communication frequencies or different communication frequency bands to the plurality of sensors.

8. The method of claim 1, further comprising setting an active mode period in which receiving of a signal is enabled and a sleep mode period in which receiving of a signal is disabled based on a transmission time of the plurality of sensors.

9. The method of claim 8, wherein the setting of the active mode period in which receiving of the signal is enabled and the setting of the sleep mode period in which receiving of the signal is disabled based on the transmission time of the plurality of sensors comprises setting the active mode period based on a transmission period at which the plurality of sensors transmit a signal and the transmission time of the plurality of sensors.

10. A non-transitory computer-readable storage medium storing a program for controlling a computer to perform the method of claim 1.

11. An apparatus for reducing power consumption, the apparatus comprising:

a sensor identifying unit configured to identify a plurality of sensors configured to transmit a signal;

a data generating unit configured to generate data to control a transmission operation of the plurality of sensors; and

a data transmitting unit configured to transmit the data to the plurality of sensors.

12. The apparatus of claim 11, wherein the data generating unit is further configured to generate data to control the transmission operation of the plurality of sensors based on any one or any combination of a number of the plurality of sensors and identification information of the plurality of sensors.

16. The apparatus of claim 11, wherein the data generating unit is further configured to generate data to adjust a communication frequency of the plurality of sensors.

17. The apparatus of claim 11, wherein the data generating unit is further configured to generate data to assign different communication frequencies or different communication frequency bands to the plurality of sensors.

18. The apparatus of claim 11, further comprising an operation mode setting unit for setting an active mode period in which receiving of a signal is enabled and a sleep mode period in which receiving of a signal is disabled based on a transmission time of the plurality of sensors.

19. The apparatus of claim 18, wherein the operation mode setting unit is further configured to set the active mode period based on a transmission period at which the plurality of sensors transmit a signal and the transmission time of the plurality of sensors.

20. A method of reducing power consumption of a receiver, the method comprising:

generating data to control a plurality of sensors configured to transmit a signal to the receiver so that all of the plurality of sensors transmit respective signals to the receiver within a single period during which the receiver is enabled to receive signals without creating interference between the signals; and

transmitting the data to the plurality of sensors.
