Evaluation of Secure Multimedia Services over Wireless Access Network

With growth of Internet and wireless IP network, multimedia systems can be accessed from any-where and anytime. However, efficient real-time services are open and challenging research problem. To implement real-time services such as VoIP over wireless access network, IP header compression scheme can be used for saving bandwidth. Enhanced compressed RTP (ECRTP) has been used for lossy link and high round trip time, primarily for wireless links. In this paper, we present an efficient solution for header compression, which is modified form of ECRTP. It shows an architectural framework for delivering real-time services to the wireless access network while using secure RTP (SRTP). We have conducted simulations to evaluate quality of services (QoS) of audio streaming.
