Abstract

Recently, the dynamic Task Offloading (TO) in the cloud computing paradigm has gained immense popularity among researchers. However, the traditional systems were ineffective due to the absence of multilevel decentralized trust management. Hence, this work proposed a multilevel decentralized trust management framework named OS-GRU and S-FUZZY-based dynamic TO in Blockchain (BC)- aided IoT Edge-Cloud Computing (ECC). Initially, the IoT devices are registered in the edge layer. Also, the DL-Scrypt is used to generate the hash code of the SLA. Then, the devices log in to the network to access the cloud resources using SLA. Similarly, the trust evaluation is done between the edge layer and fog layer using S-Fuzzy. If the trust is high then the hash code is verified in the blockchain. If verified, the tasks are clustered using k-means. Thereafter, the trust between the fog layer and cloud layer is validated, followed by load-balancing. Subsequently, the load-balanced data is inputted to the workload prediction framework. Now, the proposed OS-GRU is utilized to identify the cloud server’s workload. Next, the task’s features and cloud features are used to perform dynamic task offloading. Thus, the experimental outcomes proved that the proposed methodology had higher significance with an accuracy of 98.63 %.

支持区块链的边缘云中基于OS-GRU和s -fuzzy的多级分散信任管理动态任务卸载

近年来，云计算范式中的动态任务卸载（TO）得到了研究者的广泛关注。然而，由于缺乏多层次的分散信任管理，传统的系统效率低下。为此，本文在区块链（BC）辅助物联网边缘云计算（ECC）中提出了基于OS-GRU和s - fuzzy的多层去中心化信任管理框架。最初，物联网设备注册在边缘层。另外，还使用DL-Scrypt生成SLA的哈希码。然后，设备登录到网络中，通过SLA访问云资源。类似地，使用S-Fuzzy在边缘层和雾层之间进行信任评估。如果信任值高，则在区块链中验证哈希码。如果验证，则使用k-means对任务进行聚类。然后，验证雾层和云层之间的信任，然后进行负载平衡。随后，将负载平衡的数据输入到工作负载预测框架中。现在，建议的OS-GRU被用来识别云服务器的工作负载。接下来，使用任务的特性和云特性来执行动态任务卸载。实验结果表明，该方法具有较高的显著性，准确率为98.63 %。
