Evolving a Surrogate Model of Transaction Managementfor Mobile Cloud

Mobile cloud computing with handheld deviceshad resulted in reducing the infrastructure and administrativecosts and creating more efficient, flexible and collaborativecomputing models for business growth. However, Transactionwithin a mobile cloud faces many restrictions. Building areliable and fault tolerant transactional data managementsystem for managing large volume of data is one of the majorchallenges in mobile cloud. Multiple researches are in progressto define the new models of success in mobile cloud transaction.In this paper, we propose Surrogate Object Model ofTransaction Management for mobile cloud. Each mobile nodein the cloud sends transaction request to its surrogate objectlocated in its respective mobile support station. Surrogateobject should check its data cache for transaction executionwith a given reliability instead of sending request to databaseserver such that the network lifetime is improved. Reliabilityand fault tolerance are achieved by moving transaction requestto surrogate object and network life time is maximized bymoving the surrogate objects to less loaded base stations. Weshow via simulations that the proposed approach achieve thebetter reliability and fault tolerance and also maximize thenetwork lifetime compared to existing approaches.
