摘 ??要：物聯網中的實體大多以異構形式存在，解決異構問題是推進物聯網發展的重要因素.為此，在分析了實體及實體上載到網絡中信息的特點后，基于Agent提出一種異構實體關系服務模型.該模型具有實體信息數據處理和構建實體服務邏輯兩種功能，利用提出的全新的實體物間動態關系計算公式將異構數據轉化為物間關系緊密度（值），并依此生成了Agent服務序列，結合二分圖理論實現物聯網環境下的Agent服務邏輯;屏蔽了原本因實體和其信息的異構而使得其無法正常交互通信的缺點，實體通過模型中與之對應的Agent進行交互，并在已構建的服務邏輯下支配Agent;最后對該模型進行了仿真實驗，結果表明其可滿足物聯網環境中的用戶服務需求，在數據更新和服務準確率及沖突的處理上要優于傳統的本體語義技術對異構問題的處理結果.

Abstract： Entities mostly exist in heterogeneous forms in Internet of Things （IoT）， so solving heterogeneous issue is a vital task for developing IoT. On the basis of analysis on the characteristics of entities and their uploaded information in IoT， an agent-based heterogeneous entities relation service model was proposed. The functions of model include entity information data processing and entity service logic construction， and through using the new inter-objects dynamic relation calculation formula proposed in the paper，the heterogeneous data was transformed into their relation closeness（values），and the agent service sequence was generated based on it. Combining with the bipartite graph theory， the agent service logic was realized in IoT environment， which overcomes the heterogeneity that entities are unable to communicate with each other properly. In the model， entity interactions were completely replaced with agent interactions，and these agents were governed under the established service logic. Finally， the simulation experiment was performed on the model. And the result shows that not only can user's service requirements in IoT environment be met but also it is better than the traditional ontologies and semantics technology to deal with heterogeneous issues in the data updating， service quality and conflict handling.
