1 Core network aspects
• Process scheduling and coordination function:
DAN optionally has a capability to recognize data processing requests, coordinate the requested
processing placed at appropriate DAN elements, and schedule the processing.
• NDO and processing description retrieval function:
DAN elements optionally have a capability to retrieve data processing descriptions and the NDOs to
be processed by the requested processing.
• Explicit processing allocation function:
DAN elements optionally have a capability to allocate data processing function to a specified
location.
• Data collection function:
DAN elements optionally have a capability to collect sensor data and store the data in their storage.
• Long live period of cached data:
Cached data can optionally have long live period before the cached data are deleted. This function
is indispensable to disseminate information which is accessed by a large number of users, e.g.,
disaster-related information, using DAN.
• Consumer and cache location function:
DAN optionally has a mechanism to identify networks and geographical locations of consumers and
caches.
• NDO distribution scheduling function:
DAN optionally has a function to estimate the arrival time of mobile consumer requests to DAN
elements and the duration that the consumers are connected to the DAN elements. DAN also
optionally has a capability to schedule delivery of appropriate NDOs to the DAN elements before
the consumer arrival.
• Multiple NDO request function:
DAN optionally provides a mechanism to request multiple number of NDOs in one request.
• Vehicle-to-vehicle communication function:
DAN optionally provides the capability for a vehicle-onboard DAN element to directly communicate
with other vehicle-onboard DAN elements.
• Vehicle-to-road-side-infrastructure communication function:
DAN optionally provides the capability for a vehicle-onboard DAN element to communication with
road-side producers that give location specific information.
• Distribution of information among fragmented networks:
DAN optionally provides a mechanism to distribute NDOs while a DAN network is fragmented into
multiple DAN networks with intermittent connections among them.
• Function to specify service classes in NDO names:
DAN can optionally specify service classes in NDO names in order to provide appropriate service
quality for the communication services.
• Service class provisioning function:
DAN is optionally equipped with a mechanism to provide appropriate communication quality for
different communication services specified in NDO names.
