Fault-aware algorithm based on mutual test comparisons and probability diagnostics for mobile computing environments
Bo Han · Journal of Tsinghua University(Science and Technology) · 2011
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 mobile nodes and the mobile server station.The probability diagnosis method is used to evaluate the detection results,with different strategies used to diagnose the fault node set.The algorithm performance is theoretically analyzed with simulations showing that the algorithm satisfies fault-aware requirements for mobile computing environments,with higher diagnostic ability,lower analysis times,and less communication overhead.
