represents relationships of entity in IoO and IoI; Binary operator ⊗ indicates cartesian
product, and T represents the time set of all involving events in SWoT.
Agent Network Pattern. SWoT = (N
A , E, R, T). N
A = IoA = IoO A [ IoI A , and
N
A is IoA (Internet of Agents) that includes avatars of IoO and IoI (IoO A and IoI A ) in
SWoT. IoO A = (O, A O , E O , T O , R O ), O represents the object set in the physical world,
and in the network world, A O is the avatar of O. T O and R O indicate time set and event
relational set in IoO. IoI A = (I, A I , E I , T I , R I ), I represents the individual set in the
physical world, and in the network world, A I is the avatar of I. T I and R I indicate time
set and event relational set in IoI. While R and T, respectively, indicate R AO⊗AO [
R AI⊗AI [ R AO⊗AI [ AI⊗AO and the time set of all involving events in SWoT.
3 Conceptual Model of SWoT
SWoT has both the essential characteristics of IoT and SW (SWoT= IoT⊕ SW). For
solving intrinsic contradiction of IoT, use the characteristic of N
X to upload entity
(X = O [ I) information to the network and SW = (N
Onto , K
Onto
) (ontology network
N
Onto = O
Onto
[ I
Onto and use K network (K
Onto ) of ontology alignment in N
Onto ) to
achieve semantic annotation and reasoning.
The environment involved in the process includes physical layer and network layer,
and the main entities involved are O and I and their information. Different entities exist
in different environments, but they depend on each other. As shown in Fig. 1, entities
of network layer are abstract representations of ones of physical layer, while instantiation of network layer is physical layer. From the horizontal dimension, SWoT can be
divided into network layer and physical layer. Physical layer provides data support for
network layer, and network layer provides services for physical layer and realizes the
interoperability between physical layer and network layer.
The K
Onto is relational representation of interoperability between N
Onto ((N
Onto ,
K) = K
Onto ) and embodies the core content of SWoT.
At present, in SWoT, the technology of uploading entity information to the network
is relatively mature, such as a series of sensor systems or networks, radio frequency
identification devices, infrared sensors and global positioning systems. And ontology
technology is widely used to process the information in the network. In section above,
