QoS Ensured Bandwidth Allocation in Mobile Cloud Computing

Mahesh D.S | Shalini Pawar

Abstract: Mobile Cloud Computing (MCC) is one of the significant technology trends that we have been observing for past few years, it brings rich computational capabilities to resource constrained mobile devices. The mobile users access services from the cloud service providers through interfacing gateways in terms of certain level of Quality Of Service (QOS) even if the interfacing gateways changes due to the mobility of the mobile node. In this paper we identify, formulate and address the problem of QOS ensured bandwidth allocation among the interfacing gateways for maximizing the utility. to ensure quality of service to the mobile users bandwidth shifting at the gateways is essential, but due to varying spectral efficiency across the associated channels only shifting is not sufficient for maintaining QOS. Hence bandwidth redistribution is formulated as utility maximization problem and solved using modified descending auction. In the proposed scheme, named as advanced auction based QOS ensured utility maximization (AAQUM) each gateway submits it required bandwidth to satisfy the QOS demand from the mobile users connected to it as a bid to the auctioneer cum seller cloud service provider (CSP). During the auction process the CSP distributes bandwidth among the gateways maximizing the profit and ensuring QOS to the mobile nodes. Simulation results establish the correctness of the proposed schema.
