IP networks are on a steep slope of innovation that will make them the long-term carrier of all
types of traffic, including voice. However, such networks are not designed to support real …

Network quality of service (NQoS) of IP networks is unpredictable and impacts the quality of
networked multimedia services. Adaptive voice and video schemes are therefore vital for the …

Steganography based on bitrate modulation is a new type of information hiding approach for
Voice over IP (VoIP), which can naturally resist state-of-the-art steganalysis schemes, due to …

The effective end-to-end transport of delay-sensitive voice data has long been a problem in
multimedia networking. One of the major issues is determining the sending rate of real-time …

In recent years, Voice over IP (VoIP) call feature has become increasingly accessible to
customers due to advancements in internet services and the emergence of voice call …

Abstract Voice over Internet Protocol (VoIP) uses packet switching to transmit voice, video,
data and chat services. VoIP applications depend upon various speech codecs which vary …
