Recovery in Mobile Database System

Mobile computing is a rapidly emerging trend in distributed computing. This new mobile computing environment poses challenging problems in designing fault-tolerant systems because of the dynamics of mobility, and limited bandwidth available on wireless links. Traditional fault-tolerance schemes, therefore, cannot be directly applied to these systems. Mobile systems are often subject to environmental conditions which can cause loss of communication or data. Presented here is a scheme for recovery upon failure of a mobile host. This paper portrays the limitations of the mobile wireless environment and improvement over existing recovery scheme is presented which suit the mobile environment.
