| Abstract: | The probability of a system fault in mobile computing environments is higher due to the complexity of the mobile environment,differences in the network conditions,limited resources in the portable devices,weak connectivity,security vulnerabilities and other factors.Awareness,isolation and recovery of faults can improve system fault-tolerance.For a mobile computing environment with a central node,the mutual test comparison method can be used to obtain fault symptom information using mutual tests between the ... |
