In recent years, mobile devices such as smart phones, tablets empowered with tremendous technological advancements. Augmenting the computing capability to the distant cloud help us to envision a new computing era named as mobile cloud computing (MCC). However, distant cloud has several limitations such as communication delay and bandwidth which brings the idea of proximate cloud of cloudlet. Cloudlet has distinct advantages and is free from several limitations of distant cloud. However, limited resources of cloudlet negatively impact the cloudlet performance with the increasing number of substantial users. Hence, cloudlet is a viable solution to augment the mobile device task to the nearest small scale cloud known as cloudlet. However, this cloudlet resource is finite which in some point appear as resource scarcity problem. In this paper, we analyse the cloudlet resource scarcity problem on overall performance in the cloudlet for mobile cloud computing. In addition, for empirical analysis, we make some definitions, assumptions and research boundaries. Moreover, we experimentally examine the finite resource impact on cloudlet overall performance. By, empirical analysis, we explicitly establish the research gap and present cloudlet finite resource problem in mobile cloud computing. In this paper, we propose a Performance Enhancement Framework of Cloudlet (PEFC) which enhances the finite resource cloudlet performance. Our aim is to increase the cloudlet performance with this limited cloudlet resource and make the better user experience for the cloudlet user in mobile cloud computing.
