In this study, we analyze the extended real-time Polling Service (ertPS) algorithm, which is designed to support Voice-over-Internet Protocol (VoIP) services with various size of data packets and silence suppression in IEEE 802.16e system, by using a two dimensional Markov Chain where the grant size and the voice packet state are considered. In addition, we propose an enhanced uplink resource a...

Voice Over Internet (VOIP) is a rising popular Internet application that offers good services by Mobile Ad-hoc Network (MANET). MANET offers a appropriate platform for the deployment of multimedia and voice session over IP network in various application scenarios that provides safety to comfort related services. But this network also faces many issues on QoS because of packet drop, due to trans...

The Internet’s phenomenal growth, worldwide coverage and increasing data delivery capabilities have made possible its use as an alternative communications medium for real-time voice messages. In addition, using the Internet for voice communication circumvents the high costs of long-distance phone rates. However, the Internet is a relatively harsh environment for real-time voice communication. P...

Voice over IP (or VoIP) is a common term to refer to the different protocols that are used to transport real-time voice and video and the necessary signaling by means of the Internet Protocol (IP). H.323 [1] is an ITU-T standard for real-time voice and video communication over packet networks. During the past two years it has become the standard on the Internet for VoIP. Another relatively rece...

Internet telephony (or VoIP) has been viewed in two different ways. First, some hold that it is largely similar to earlier architectural changes in the PSTN, continuing the transition from analog to circuit-switched digital and now to packet-switched transmission. Others believe that Internet telephony is primarily another Internet application that happens to interconnect with a “legacy” networ...
