Session mobility in multimedia services enabled by the cloud and peer-to-peer paradigms

Abstract

Abstract-Services based on new information technology offering audio and video modality are viewed among the most important today. When users change location or device there is a need to keep these media sessions active.The main purpose of this article is to present a lightweight framework that allows session mobility through making profit of the cloud and peer-to-peer paradigms, while at the same time fulfilling the prevailing requirements for new session mobility multimedia services.We demonstrate the principles of the framework by creating a real prototype, allowing combined video and audio sessions to be migrated between devices, thus showing successful implementation of session mobility meeting requirements such as low degree of service provider dependency, no changes to current common network infrastructure, dealing with privacy issues, providing flexibility and low cost, and letting the user control when and where to migrate the sessions.It is our belief that relatively new paradigms such as peer-topeer computing and cloud services could enhance and support flexible session mobility in a mobile use context.

Inter-screen interaction for session recognition and transfer based on cloud centric media network

“…S. Mate et al [6] investigated device centric, network centric and hybrid approaches for session transfer. In [7], a lightweight framework for session mobility through the synchronized profits in the cloud and peer-to-peer nodes, was discussed. In [8], they set a separate session information server to enable the seamless session transfer among different terminals.…”

Web-based adaptive application mobility

“…This emerging mobile landscape of new small and powerful devices combined with far-reaching wireless networks and ever-growing bandwidths has both enhanced and brought on new challenges to all kinds of mobility aspects, e.g. service mobility (making services available regardless of devices or networks used), session mobility [3] (seamlessly keeping media streams active although switching user location, network and/or device) and of course terminal mobility.…”

A MIP-P2P based architecture for application mobility

“…There are four traditional types of mobility [14]: terminal mobility, allowing a device to change location and still be able to communicate; personal mobility (or user mobility), when a user can keep his or her user identity irrespective of terminal or network; session mobility [17] (or continuous Permission to make digital or hard copies of all or part of this work for personal or classroom use is granted without fee provided that copies are not made or distributed for profit or commercial advantage and that copies bear this notice and the full citation on the first page.
