The present disclosure provides methods and Internet of Things (IoT) systems for determining a fire rescue plan in a smart city. The method includes obtaining monitoring data of a disaster area in a first period of time; predicting fire information in a second period of time based on the monitoring data; determining flow information of the disaster area based on the monitoring data, the flow information including at least one of traffic flow information or human flow information; and determining a rescue plan based on the fire information and the flow information, the rescue plan including at least one of a count of fire trucks or a count of ambulances.

A trajectory prediction method and apparatus, a storage medium, and an electronic device are provided. In embodiments of this disclosure, according to a historical trajectory of a designated target and a historical trajectory of each obstacle, a historical interaction feature between the designated target and each obstacle is determined, and a motion trajectory of the designated target is predicted to obtain an initial predicted trajectory. A future interaction feature between each obstacle and the designated target is then determined according to the initial predicted trajectory and a planned trajectory of each obstacle. According to the future interaction feature, a final predicted trajectory of the designated target is obtained.

An apparatus including a device property data processing circuit, a change detection circuit, an alert circuit, and an alert provisioning circuit. The device property data processing circuit is structured to at a first time, interpret, device property data corresponding to a device registered with an IoT device registry, and at a second time, interpret, the device property data corresponding to the device registered with the IoT device registry. The change detection circuit is structured to detect a change in the device property data between the first time and the second time. The alert circuit is structured to generate, responsive to the detected change, a message that identifies the device corresponding to the device property data. The alert provisioning circuit is structured to transmit the message.

An apparatus for provisioning embedded Internet of Things Universal IDs (IoT UIDs) in Brownfield devices. The apparatus includes a display circuit, a requestor circuit, a request provisioning circuit, an IoT UID processing circuit, and an IoT UID provisioning circuit.
