In the fifth generation of mobile networks (5G), managing the high traffic volume of applications and the needs of active objects in this network requires a strong, isolated, and secure platform. This is achieved by using the new concept of network slicing. DBNS (a distributed approach based on blockchain) is a method of allocating resources in terms of network slices. Unfortunately, this method faces a security issue caused by the non-observance of data transparency. A smart As a result of the allocation of resources between providers, this article utilizes the smart contract feature of the blockchain to create data transparency, as well as a secure communication platform, in the context of network slicing and among different service providers (SPs), creating a service and even reducing the delay imposed on the network. In this paper, we present a smart DBNS approach that uses smart contracts and blockchains to make interactions between SPs more secure and smart. The simulation results of the proposed method show that on average, the service delivery delay is reduced by 18% and 5%, respectively, in the two parts of the uRLLC and mMTC networks, and it promotes a new approach in the integration of these two technologies.
