Patent ID: 8583792

Claim:
A system, comprising: a first sensor designated as a primary sensor and a second sensor designated as a secondary sensor, wherein each of the primary and secondary sensors comprise a memory subsystem and a processor in data communication with the memory subsystem, wherein the processors of the primary sensor and secondary sensor are respectively programmed to cause the primary sensor and the secondary sensor to perform operations comprising: transmitting, from each the primary and secondary sensors, information probes to a host device, each of the information probes being prioritized according to their probe types; determining, at the primary sensor, whether a second probe type is prioritized higher than a first probe type, the second probe type being a probe type of a highest priority information probe for which a reply from the host device was received at the secondary sensor and the first probe type being a probe type of a highest priority information probe for which a reply from the host device was received at the primary sensor; in response to determining the second probe type is not prioritized higher than the first probe type, monitoring the host device by the primary sensor; and determining, at the primary sensor during the monitoring, that the host device is offline in response to a failure to receive a reply from the host device to an information probe transmitted from the primary sensor, and in response to the determination that the host device is offline: determining whether the second probe type is prioritized equally to the first probe type, and in response to determining that the second probe type is prioritized equally to the first probe type: transmitting, from the primary sensor, data indicating a probe handover to the secondary sensor; and monitoring the host device by the secondary sensor.
