A Framework of Mobile Cloudlet Centers Based on the Use of Mobile Devices as Cloudlets

Accessing remote cloud services usually involves high network latencies. To deal with this issue, several models of local cloudlets have been proposed, but most of which are based on powerful desktop machines running continuously and constantly to provide services to nearby users. In this paper, we propose a more ubiquitous solution based on less powerful but considerably more accessible machines, namely mobile smartphones. We envision a network of cloudlets distributed within a geographic area, connected to a root server that keeps track of their online presence and resource availability. Our framework is especially suitable for environments where cloud clients are interested in network and software services, in information and data generated and updated by applications or cached from accesses to remote cloud centers. We use the CloudSim simulator to evaluate the performance of the proposed solution and compare it with a peer solutions found in the literature.
