establish a set of Agents mapping to all entities in the network. Through the interoperability or communication mechanism between Agents, the dynamic relationship
between entities can be solved, and the dynamic relationship networks between entities
in SWoT can be realized, so as to solve the intrinsic contradiction of IoT.
In summary, in the physical layer of SWoT, each physical entity has a corresponding Agent in the network layer, forming the hierarchical structure of the vertical
dimension, shown in Fig. 2. Object set (O) and corresponding Agent set (A O ), as well
as the interaction between them, constitute an independent set of IoO, which can
independently realize the dynamic relationships between objects and the derivation of
deeper relationships. E O⊗I [ I⊗O and R O⊗I [ I⊗O are the carriers of the relationships
between IoO and IoI.
As shown in Fig. 2, the uploaded information of O and I is processed by A O and
A I , respectively, and then, the result is fed back to the underlying O and I, forming that
real-world entities provide data support for the avatar in the network layer. On the
contrary, A O and A I meet the service needs and finally form a virtuous circle. The
explanations of Ot L , Ot G , and Ot G-S are in following section.
4 Reasoning Model of Dynamic Relationships Between
Entities
Definition 1 In dictionary, the “relationship” is defined as the state of interaction
between things (Thing1 R Thing2), which indicates the relationship R between Thing1
and Thing2. If the state of thing is independent from time, then R is a static relationship.
Definition 2 Dynamic relationship is a relationship that adds time factor to the original
one, which is Thing1 (R, T) Thing2. It means that under the influence of time
T, Thing1 and Thing2 have relationships, and the relationships will change with the
time.
