Nowadays, Mobile Cloud Computing (MCC) is widely accepted as a concept that can significantly improve the user experience when accessing mobile services. For MCCs, a stable and reliable topology is an important research topic. However, the problem of reaching consensus in the distributed system is one of the most important issues to design a fault-tolerance system. The protocols of reaching consensus are required so that the distributed system still can be well performed even if certain components in the system were failed. In this study, the Trusted Timely Computing Base (TTCB) is used when the message is transmitted. However, the consensus problem is revisited with the assumption of transmission medium failure on malicious faults in the Cluster-based MCC in this study. The proposed protocol, Trustworthy MCC (TMCC), can make all fault-free nodes reaching consensus with minimal rounds of message exchanges and tolerate the maximal number of allowable faulty components.
