Voice communication over internet not be possible without a reliable data network, this was first available when distributed network topologies were used in conjunction with data packets. Early network used single centre node network in which a single workstation (Server) is responsible for the communication. This posed problems as if there was a fault with the centre node, (workstation) nothin...

. Voice over Internet Protocol is an upcoming technology. VoIP enables voice communication through the Internet. Internet provides lot of services to the people. VoIP differs from conventional networks. The online transmission of audio data over networks faces lot of problems. Real time voice transmission is not as easy as ordinary text data. Networks are not designed to support real time commu...

Due to the rapid growth of the internet, customers request more applications over internet such as telephony and video. VoIP (Voice over Internet Protocol) is an emerging technology for voice communication which deploys many techniques to produce a high-quality service. Signaling is one of success keys of Voice over IP; the two most promised approaches in this case are H.323 and SIP. This paper...

Voice over Internet Protocol (VOIP) is one of the most notable applications of internet. Some other well known terms used for VOIP in literature include IP telephony or Internet telephony. It can be a better replacement for the traditional telephone systems because of its high resource utilization as well as low cost. Beside this, wireless LAN Network (WLAN) has emerged as a robust networking t...

VoIP over Mobile WiMAX provides high data rate voice connectivity to high speed mobile as well as to fixed users. Voice over Internet Protocol (VoIP) enables the transport of voice data over internet protocol base networks. The WiMAX mobile network provides data services to both mobile as well as pedestrian users and the quality of voice is greatly affected with the mobility patterns of mobile ...

Voice over Internet Protocol (VoIP) is one of the fastest growing Internet applications. It is a viable alternative to the traditional telephony systems due to its high resource utilization and cost efficiency. Meanwhile, Wireless Local Area Networks (WLANs) have become a ubiquitous networking technology that has been deployed around the world. Driven by these two popular technologies, Voice ov...

The Internet is becoming a massive knowledge resource for 3D multimedia information such as movies, news clips, and children’s stories. Multimedia information can be interactively modified using multimodal interfaces for entertainment to incorporate subjective perception in a scenario and to analyze situations using many what-if scenario modifications. In this paper we describe an XML voice int...

Voice communication is an emerging technology and has great importance in our routine life. Perceptual, Voice over Internet Protocol quality is an important issue for VoIP Apps services because VoIP Apps require real-time support. Many network factors (packet loss, packet delay, and jitter) affect to VoIP quality, to achieve this objective we used an approach based on Fuzzy Logic. We configure ...
