Migrating web application sessions in mobile computing (original) (raw)

Abstract The proliferation of different kinds of mobile devices, ranging from personal wireless devices, such as PDAs and smart phones, to small notebooks, is enabling ubiquitous personal computing. However, even if a personal device is able to access to different kinds of information, often it does not represent the best solution to retrieve a stream of data from the Internet or to visualize it with an acceptable quality.

Application mobility is achieved when migrating an application with its code, states and all related information from one device to another during its execution. As traditional applications are being challenged by apps, we believe it is time to rethink the notion of application mobility and explore the concept from a web perspective. More specifically, this paper aims to address the challenges associated with application mobility through mapping these against features within modern web technologies, analyzing their ability to meet the specific requirements of application mobility. An architectural proposal is described where we deploy application mobility using web technologies. We show that the emerging HTML5 standard along with related API:s and frameworks can provide an environment for delivering application mobility that strongly meets the requirements of support for offline work and heterogeneous environments.

In mobile computing and wireless communication, proxies are mainly used to overcome the three major problems of these networks: throughput and latency differences between the wired and the wireless links, host mobility, and limited resources of the mobile hosts (MH). This report aims to present a general classification of proxy-based approaches, describe the most frequent functions assigned to proxies, discuss
