Endogenous Trusted DRL-Based Service Function Chain Orchestration for IoT

Abstract : With the development of the Internet of Things, trust has become a limited factor in the integration of heterogeneous IoT networks. In this regard, we use the combination of blockchain technology and SDN/NFV to build a heterogeneous IoT network resource management model based on the consortium chain. In order to solve the efficiency problem caused by the full amount of data on the chain, we deploy light nodes and full nodes for the consortium chain. At the same time, we use the idea of identification to realize the separation of identification and resource information, build the application mode of on-chain identification and off-chain information, and realize resources endogenous trust management. We also propose a practical Byzantine fault-tolerant consensus mechanism based on reputation value to save consensus costs and improve efficiency. Combined with artificial intelligence technology, we introduce deep reinforcement learning for service function chain orchestration, and design a service function chain orchestration algorithm based on Asynchronous Advantage Actor-Critic to optimize orchestration costs. The final simulation results show that the consensus algorithm and service function chain orchestration algorithm we designed have good performance in terms of cost saving and efficiency improvement.

 EXISTING SYSTEM :

 ? THz based communications require rethinking of existing solutions and investigate novel approaches that offer a seamless operation over the entire THz band. ? Various shortcomings in existing wireless communications has led to the foundation for the next generations. This paper provides a detailed survey on 6g wireless network. ? Upcoming technologies such as artificial intelligence (AI), virtual reality, and the Internet of Everything (IOE) require low latency, ultrahigh data rates and reliability, for the uplink and downlink which cannot be satisfied by existing 5G?s ubiquitous mobile ultra-broadband, ultrahigh-speedwith-low latency communications, and ultrahigh data density.

 DISADVANTAGE :

 ? In order to overcome the interference problem, inter-cell cooperation has been studied in LTE under the name of coordinated multi-point (CoMP) transmissions or network MIMO. ? The main problem is that while globally optimal policies are known and can be computed in principle (see, e.g.,for the max-min fairness policy), these policies do not scale neither in performance nor computationally. ? In symbiotic radio networks, the user association problem can be solved with limited environmental information using DRL. ? UAV communications involve some security and privacy problems such as eavesdropping and jamming. These problems may pose threats to personal information, so it needs to be comprehensively investigated.

 PROPOSED SYSTEM :

 • In the framework of PoX, enormous alternative mechanisms have been proposed in terms of cost, eco-friendliness, fairness and performance. • Fast smart contract deployment (FSCD) is an advanced mechanism proposed for accelerating and securing the service in B-RAN . • By implementing the concept of template in smart contracts, the root contract in FSCD defines the service terms in detail, which is later automatically applied to all services. • In order to implement the proposed design and better test its performance, we assess the basic capability needs in B-RAN and construct a corresponding prototype.

 ADVANTAGE :

 ? The key contribution of their study is to demonstrate how the presence of foveated rendering can improve the rendering performance by reducing the field of view. ? It is necessary to optimize the performance of the cloud rendering pipeline. ? The future C-V2X architecture should support the deterministic transmission, in additional to the enhanced performance of latency, reliability, and throughput. Synchronization is the premise. ? These new technologies not only provide enhanced transmission performance, but also provide positioning, sensing, and 3D imaging capabilities. ? Iterative processing is used in the SCC decoder, and a performance similar to that of a classic PCC may be achieved.
