Blockchain-Based Reputation Management for Task Offloading in Micro-Level Vehicular Fog Network

Sarah Iqbal, Asad Waqar Malik, Anis Ur Rahman, Rafidah Md Noor
2020 IEEE Access  
In this work, we propose a secure fog computing paradigm where roadside units (RSUs) are used to offload tasks to nearby fog vehicles based on repute scores maintained at a distributed blockchain ledger  ...  The experimental results demonstrate a significant performance gain in terms of queuing time, end-to-end delay, and task completion rate when compared to the baseline queuing-based task offloading scheme  ...  The framework maintains a distributed ledger at RSUs maintaining a social reputation against every vehicle in the vehicular network.  ...
