The concept of a smart city is intertwined with a kind of great data management, and through which, reaching optimal management. The data transaction and the issue of communication between different equipment are all defined on the IoT platform. The concept of IoT is a general keyword referring to the widespread communication between equipment. Nevertheless, the idea that metropolitan management can be implemented with the targeted data processing faces challenges. On the other hand, multicarrier energy management, in which various types of energy generating structures like microgrids, smart grid, energy hub systems, transportation sector, etc. converge together in an optimal energy management program, is of great difficulty. Considering these challenges, the processes of encryption, dispatching data, decryption with the algorithm of the energy management plan should be intertwined and all solved together as a general problem. The current paper has presented a modified IoT architecture along with a multi-carrier energy management application through integrating two distributed and integrated management approaches. In the presented model, each energy-generating agent in the first layer initially controls its own internal supply and demand rate implementing distributed management, and then in the second layer, each agent participates in a macro-competitive market to achieve the optimal work point. Thus, in the presented model, the data blockchain building protocol based on The Advanced Encryption Standard (AES) in IOT platform is synchronized with the cloud-computing center and an integrated energy and data security management program is run, having the nature of the competitive market according to the block building time by each agent. According to the results, in this approach, while achieving the desired answer, the volume of data transaction and consequently, the time to gain the final consensus may be considerably reduced.
