SMiLE - Session Mobility in mobiLe Environments

Abstract

Nowadays most people own several devices, like a notebook or a smartphone, for satisfying their mobility and flexibility needs. Without special arrangements a program, its execution state and saved files-the latter two are commonly called “session”-are confined to a physical host. Session Mobility enables the user to break this law of locality, and instead creates a relation between the session and himself. In this paper we present a novel system for supporting session mobility in various scenarios. To support an almost automatic session handover between different devices a mobile agent system has been used. The selection of target devices has also been automated based on the usage context, the device's capabilities and a rough estimation of the actual location. Based on the Session Mobility in mobiLe Environments platform (SMiLE) a use case has been realized where a video session is migrated from a notebook to a smartphone and vice versa.
