Experimental Verification of Docker-Based Distributed Cloud Applications for Secured Mobile VoIP

Cloud computing paradigm has been driving the cloud-leveraged refactoring of existing ICT services including VoIP. In this paper, we design and prototype secured mobile VoIP services with open-source Asterisk PBX software by employing Docker lightweight virtualization for mobile devices. We also experimentally verify the quality of secured voice and the associated communication delay over distributed global connectivity environment.
