摘要: Abstract Cloud radio access network (C-RAN) supports the explosion of Internet Things (IoT) applications and demand for massive in 5G networks. However, centralized trustless operators causes severe malicious insider threats, such as maliciously tamper accidentally delete data. Blockchain, a traceable non-tamper distributed ledger maintained by all nodes, has been considered feasible method to overcome these while size blockchain is limited practical byzantine fault tolerance (PBFT) consensus algorithm where participants, nodes who participate algorithm, bring heavy communication traffic. In this paper, we first propose C-RAN enabled (BC-RAN) with PeerTrust-based PBFT (Trust-PBFT) prevent threats scale up network. We also tri-chain structure divide transactions into three categories storage facilitate traceability. The calculates trust value each node, those high values will be elected participants PBFT. Simultaneously, due introduction PeerTrust, another benefit improve performance efficiently. Besides, an adjustment mechanism designed-newly implemented impede effects produced Finally, several simulation experiments are designed evaluate compare fault-tolerance scalability Trust-PBFT.
