A novel cloudlet-based communication framework for resource-constrained devices

In this paper, we present a new emerging technology for building mobility-enhanced and small-scaled mobile to cloud applications called Cloudlet. We address the reliability challenges in affording a powerful computing resources to the mobile applications. The proposed system connects to different end points (mobile, sensors, computer) in order to collect information and send it to the cloud server. In addition, the integrated system allows users to make autonomic applications and send intelligent commands to the cloud in both on-line and off-line mode. The system integrates heterogeneous wireless devices (embadded system, sensors, integrators) and various communicating technologies (WiFi IEEE802.11n, GSM/GPRS, 3G, etc) to enable connectivity which is monitored by a cloud Internet-of-Things platform. The performance of GPRS/GSM based framework is evaluated under realistic conditions to ensure data synchronization between Cloudlet and Cloud. The results showed that the proposed approach increases the downstream throughput from the Cloud to the Cloudlet.
