Unleashing the potential of the Internet of Things 3

I.5 Transfer of events across different application domains
In many IoT applications such as smart city and emergency management applications, events that
happen in one application domain are transferred to other relevant application domains. Based on
events transferred across different application domains, different applications can work
collaboratively so that more functions and services can be provided than those specific to a single
application domain. Examples of such use cases include events transferred between road and bridge
maintenance applications, between traffic management and driving applications, between weather
forecast and flood prevention applications, etc.

Such use cases need that the events be described in a standardized format so the different IoT
applications can understand them. Furthermore, the events should be transferred reliably and securely.

I.6 Data sharing across different application domains

Some data are of importance not only in the IoT application where such data are collected, but also
in other IoT applications. Such data includes geographic position data, road traffic data, etc. In
accordance with appropriate regulation and laws, data may also be shared across different application
domains thus allowing for more functions and services to be provided. For example, data related to
the geographic position of mobile phones might be used for calculating the road traffic.
Such use cases need standardized data formats among the different IoT application domains so that
data can be shared across different application domains.

I.7 Integrated operating centre for smart city
Smart cities developed based on IoT infrastructure are becoming a new trend in city development all
over the world. In the future, cities will need to have an intelligent "brain" system to analyse different
kinds of data collected by IoT devices and to act upon their analysis and other related actions. Such
a city brain system may be referred to as an "integrated operating centre for a smart city".
This integrated operating centre basically requires data sharing, aggregation and processing across
multiple application domains. For example, implementations of such an integrated operating centre
usually require the integration of urban real-time operational status information with event
monitoring, data analysis, intelligent early warning and information dissemination, intelligent
decision-making and integrated command and dispatching.

I.8 One detailed use case: traffic accident information collection
An ITS-station (ITS-S) inside a vehicle that is directly involved in or is passing by an accident detects
that a crash has happened and starts an accident reporting process automatically. It tries to connect to
the IoT and then sends the accident report to it. The IoT receives and verifies the accident report and
the analysis result is pushed to the service subscribers, i.e., a Police Station and a Rescue Centre.

The service subscribers can ask the IoT to collect more information about the accident. The IoT
receives these service requests and then asks the ITS-Ss to collect some more information according
to the requests of the subscribers. The ITS-Ss in proximity to the accident site receive, verify, parse
and execute the received commands, i.e., take pictures, get current travel status, generate reports, sign
the reports and upload signed reports to the IoT. The IoT accumulates and verifies the reports
uploaded by the ITS-Ss and then generates a report containing visual information about the accident
scene for the Rescue Centre and a report about the traffic situation near the accident site. These reports
are again pushed to the Rescue Centre and Police Station respectively.
The rescue centre analyses the report about the accident scene and then formulates a specific rescue
plan. The police station analyses the report about traffic situation and formulates a specific traffic
control plan.
This use case requires device-initiated communication capability, secure and trust communication
capability and event-driven collaboration among different applications.
