Performance analysis of audio streaming in secure wireless access network

Advances in the Internet and multimedia technologies have spurred many research efforts in Internet-based multimedia access system. In this paper, we presented such a model and framework for delivering real-time traffics to a wireless access network over public Internet protocol (IP) backbone network. We have presented a performance analysis of audio streaming when IP tunneling network using generic route encapsulation (GRE) along with Internet protocol security (IPSec) is implemented. The impacts on performance, with particular attention to Quality of Service (QoS) characteristics have been evaluated through a series of experiments. In this paper, the effects of a compression scheme based on compressed real-time transport protocol (CRTP) and resource reservation protocol (RSVP) are analyzed when delivering real-time traffics to the wireless access network through secured IP network.
