Abstract: The information interaction between huge heterogeneous entities existed in Internet of Things（IoT） leads to the internal contradiction for IoT. To solve this problem, a method of multi-agent-based inter-objects dynamic relation discovery is proposed. Firstly, abstract all entities in IoT to corresponding Agents. Secondly, employ ontology-based semantic matching and improved calculation method of inter-objects dynamic relation to calculate object dynamic relation for the individual. Finally, converse the original heterogeneous entity relation into the close-ranked dynamic network relation between Agents. The experimental verification reveals that the relation network constructed by the proposed method can obviously improve the interaction contradictions among heterogeneous entities. And compared with the original similar method, both accuracy and error rate have been improved, confirming the proposed method correct and feasible.
