Abstract
An electronic device may include a processor and a network interface that may include a first radio and a second radio. The processor may be configured to perform wireless communication jamming attack detection by occasionally performing clear channel verification utilizing the network interface to determine whether a threshold number of devices' channels are incapacitated in a wireless network within a threshold amount of time and/or by sending a heartbeat signal from the first radio and determining whether the second radio received the heartbeat signal.
Claims21
(canceled)
An electronic device, comprising:
- a power source configured to provide operational power to the electronic device;
- a network interface comprising a wireless radio, the wireless radio being configured to wirelessly communicate with a plurality of electronic devices over one or more wireless channels;
- and
- a processor in communication with the network interface, the processor being configured to:
- learn steady-state characteristics of the plurality of electronic devices that communicate over the one or more wireless channels;
- perform a clear channel verification utilizing the network interface of the one or more wireless channels, wherein the clear channel verification considers the steady-state characteristics when performing the clear channel verification;
- and
- determine, based on the clear channel verification, whether any wireless channels of the one or more wireless channels are incapacitated.
A tangible, non-transitory computer-readable medium comprising instructions configured to be executed by one or more processors of an electronic device, the instructions causing the one or more processors to:
- learn steady-state characteristics of one or more electronic devices that communicate over one or more wireless channels;
- perform a clear channel verification of the one or more wireless channels utilizing a wireless network interface, wherein the clear channel verification considers the steady-state characteristics when performing the clear channel verification;
- and
- determine, based on the clear channel verification, whether any wireless channels of the one or more wireless channels are incapacitated.
A smart-home device system, comprising:
- a plurality of smart-home devices;
- and
- a smart-home hub device, comprising:
- a power source configured to provide operational power to the smart-home hub device;
- a network interface comprising a wireless radio, the wireless radio being configured to wirelessly communicate with the plurality of smart-home devices over one or more wireless channels;
- and
- a processor in communication with the network interface, the processor being configured to:
- learn steady-state characteristics of the plurality of smart-home devices that communicate over the one or more wireless channels;
- perform a clear channel verification utilizing the network interface of the one or more wireless channels, wherein the clear channel verification considers the steady-state characteristics when performing the clear channel verification;
- and
- determine, based on the clear channel verification, whether any wireless channels of the one or more wireless channels are incapacitated.
