Internet of things - Collaborative information
processing reference model
1 Scope
This Standard proposes the collaborative information processing reference
model of tasks or services in the Internet of Things system, and specifies entity
functions and collaborative information processing processes.
This Standard applies to the design and development of collaborative
information processing in IoT systems.

3.1 Collaborative information processing
An information processing process in which multiple entities cooperate with
each other to accomplish a certain task or provide a certain service.
Note: Rewrite GB/T 30269.401-2015, definition 3.2.
subtasks and the needs of entities in terms of sensing,
storage, computing, dynamically plan and monitor
interactions and collaborations between subtask
executive entities, indirectly achieve data sharing and
resource complementation between subtask executive
entities, so that each entity completes subtasks.
Distributed
subtask
processing
During subtask processing, each subtask executive
entity uses user-defined rules or self-learning
mechanisms. The entities directly perform interaction
and collaboration with each other, and autonomously
adjust the needs of each entity in terms of sensing,
storage, and computing according to the needs of the
subtask, realize data sharing and resource
complementation between subtask executive entities, so
that each subtask executive entity completes subtasks.
Hybrid subtask
processing
During subtask processing, some subtask executive
entities cooperate to complete subtasks in a distributed
subtask processing mode, and some subtask executive
entities complete subtasks in a centralized subtask
processing mode.
Capability
monitoring
Sensing
capability
monitoring
Collect the performance parameters and operating
status data (such as sensor modalities and their
configuration, sensing range, location) of subtask
executive entities in real time or at regular intervals, and
analyze them.
Computing
capability
monitoring
Collect the performance parameters and operating
status data of the processors of the subtask executive
entities in real time or at regular intervals, and perform
analysis.
Communication
capability
monitoring
Collect the communication performance parameters and
status data of the subtask executive entities in real time
or at regular intervals, and perform analysis.
Other
capability
monitoring
Collect performance parameters and status data other
than the sensing, computing, and communication
capabilities of subtask executive entities, such as
storage, visualization and other performance
parameters, in real time or at regular intervals, and
perform analysis; sensor data characteristic information,
signal-to-noise ratio, signal strength, distance estimation
of single target (or multiple targets) and entities, state
parameter estimation, etc.
Capability declaration
Subtask executive entity reports its own sensing,
computing, communication, and other capabilities to the
collaborative entity.
a) Task decomposition phase:
1) Task input: the collaborative strategy planning function entity obtains
task requirements and description information, as shown in (1) of
Figure 3;
2) Task decomposition: the collaborative strategy planning function entity
decomposes the task into subtasks according to the capability
declaration information of task and entity, and sends the subtask and
entity capability information to the capability assessment function entity,
as shown in (2) of Figure 3;
3) Send the capability assessment result: the capability assessment
function entity completes the capability assessment of the entity
according to the capability declaration of each entity and the degree of
matching between subtasks, and sends the entity's assessment result
to the collaborative strategy planning function entity, as shown in (3) of
figure 3;
4) Task allocation: according to the task information and capability
assessment results, the collaborative strategy planning function entity
determines subtasks and subtask executive entities, determines
centralized, distributed, and hybrid subtask processing modes, and
sends subtask information to the corresponding subtask executive
entity, as shown in (4) of Figure 3.
b) Subtask processing phase:
1) Subtask processing information interaction: according to the centralized,
distributed, hybrid subtask processing mode, entities perform subtask
processing information interaction. Distributed subtask information
interaction occurs between subtask executive entities, as shown in (5-
1) of Figure 3; centralized subtask information interaction occurs
between collaborative strategy planning function entities and subtask
executive entities, as shown in (5-2) of Figure 3; hybrid subtask
information interaction includes distributed [(5-1) of Figure 3] and
centralized [(5-2) of Figure 3];
2) Subtask processing: according to the centralized, distributed, and
hybrid subtask processing mode, each subtask executive entity
completes its subtask processing and informs the collaborative
effectiveness assessment function entity of the processing result.
c) Collaborative effectiveness assessment phase:
1) Collaborative effectiveness assessment: the collaborative effectiveness
assessment function entity performs summary, combination, and
