Developing Challenges for a Cloudlet Solution of a Multi-lingual Dictionary Application

Cloud Computing is a recent trend technology that moves the World forward. It helps the mobile users to run computationally-intensive and memory-demanding applications on a remote cloud and access the results on their mobile devices. The usual processing of the cloud based applications is realized via a WAN connection. However, this approach is inefficient for real-time applications due to the relatively huge WAN latency. Cloudlet is a small cloud located near the mobile user, which can perform the same processing tasks as a remote cloud by using Virtual Machines (VMs), but its position close to the mobile phones enables them faster response, avoiding huge WAN latencies. In this paper we present details on development of a multilingual dictionary application running on a mobile device. The application will use VMs installed on the cloud/cloudlet for execution of the tasks and presenting the results on the mobile device. The user can insert a word for translation and find the corresponding meaning in a selected language. The mobile device will be used for data input, by inserting the word and for data output, presenting the result. The process execution (translation) will be realized on the cloud/cloudlet. Although the initial version supports translation between two languages, it can be easily expanded to support multilingual translation. We present several design details and provide a proof of a concept by developing a prototype and implementing the solution in a cloud environment.
