<p><b>Abstract</b>—Application recovery in Mobile Database Systems (MDS) is more complex because of an unlimited geographical mobility of mobile units. The mobility of these units makes it tricky to store application log and access it for recovery. This paper presents an application log management scheme, which uses a mobile-agent-based framework to facilitate seamless logging of application activities for recovery from transaction or system failure. We compare the performance of our scheme with lazy, pessimistic, and frequency-based schemes through simulation and show that compared to these schemes, our scheme reduces overall recovery time by efficiently managing resources and handoffs.</p>
