Policy Based Fault Tolerant Scheme in Pervasive Computing

-Pervasive computing integrates digital and physical devices. Users can access digital data and applications from the environment as easily as accessing them through their computers. The system has to be flexible to various kinds of faults and should be able to function even though the fault occurs. This paper deals with various classes of failures, their implication to pervasive computing, the challenges to be addressed in designing a fault tolerant pervasive computing system and a policy based fault tolerant pervasive computing system where the policy deals with the separation of the program into distinct features. This policy based approach is more flexible and adaptable.
