The Research And Implementation Of Mobile Cloud Computing Platform Based On OpenStack

Mobile cloud computing is a new technology which is now developing rapidly.With its rapid development,how to efficiently deal with the data storage and computing that are transmited by a large number of mobile terminals has become a serious challenge.OpenStack can be used as a kind of very effective solution for IaaS,through this solution,the large enterprises can integrate a lot of hardware resources and provide storage or computing services to Individuals or small and medium-sized enterprises.In the process of providing services,we are inevitably involved for the instance node of virtual machine access,operation control,load balance of the virtual cluster and many other problems.Now the instance cluster nodes' access tools for the OpenStack are all based on a Web application,so there is no mobile devices(such as Android phones)that can be using on OpenStack cluster control.In view of the above problems,this paper puts emphasis on analyzing the operation principle of OpenStack cloud platform,the characteristics of its components and the management of the instance of the virtual machine.Using the OpenStack cloud platform,this paper analyses the main function of the MobileStack that need to be implemented and gives the requirements analysis,design and implementation for the three subsystems of MobileStack(Monitoring Server Subsystem,Controller Server Subsystem and Mobile Terminal Subsystem),so we can realize the seamless docking for the PC-Mobile-Cloud.Through in-depth studying and comparing with the related technologies and algorithms of load balancing,this paper puts forward a kind of improvement for consistent hashing algorithm and set up the test environment in the virtual node instance cluster environment.We use the JMeter to simulate users' request,through the experiments we can compare the traditional consistency of the hash algorithm and the improved algorithm for instance node load balancing.
