Recovery of mobile transactions

Abstract

This paper addresses the recovery and rollback problem in mobile transactions (MT). We propose mobile transaction recovery protocols to model recovery in a mobile computing environment. In the proposed model the mobile host (MH) and the mobile support station (MSS) communicate with each other through messages which are logged at MSS. The image of mobile transaction is created through these message logs on MSS. In the recovery of mobile transactions these image transactions and message logs are extensively used. The recovery algorithms work in the mobile computing environment with different kinds of failures and transaction rollback.
