The fault-tolerance is an important research topic in the study of distributed systems. To cope with the influence from faulty processors, reaching a common agreement in the presence of faults before performing certain special tasks is essential. However, a Mobile Ad-hoc Network (MANET) may suffer from various types of processor failure. In order to enhance the fault-tolerance and reliability of the MANET, the Byzantine Agreement problem in the virtual subnet network of MANET is revisited in this paper. The proposed protocol can make each healthy mobile processor reach an agreement value to cope with the faulty component in the virtual subnet network.
