Multi-service Handoff Mechanism with QoS Support in Mobile Cloud Computing Environment

Abstract

Mobile devices are becoming the primary platforms for many users who always roam around and access the cloud computing applications. Mobile Cloud Computing (MCC) is the combination of cloud computing, mobile computing and wireless networks. Here we focus on the mobile cloud computing where the mobile device acts like a thin client connecting to the remote server through wireless network. We propose an improved multi-services handoff mechanism, which uses the list method of session initial protocol to make all active services execute handoff together. The mobile devices experience the problem when obtaining the multiple cloud services during the handoff process. The mobile users get storage facility by connecting with cloud through wireless network. We propose energy detection (ED) analytical model for handoff process that calculates the energy consumption for each handoff process in the cloud computing environment. Analytic model and simulation are developed to investigate the new mechanism. Our ED analytic model is developed to examine the consumed energy for different handoff processes in cloud computing. The model helps the mobile users to get prior information for the status of the mobile when executing the handoff process. The mobile device realizes the integrated handoff signaling procedure which saves much energy consumption.
