providing a high-quality service for transmission and playing real-time voice conversations (voice streaming) over wireless ad-hoc networks is no mean feat. buffering together with adjusting the playout time of the packets is a receiver-side solution to overcome this challenge. in this paper, a new adaptive playout adjustment algorithm is proposed to stream the voice conversations over wireless...

Abstract CDMA2000 1X, one of the world’s first commercial third generation (3G) systems, offers high-speed data services in conjunction with the voice service. This high data rate capability of CDMA2000 1X enables delivery of real-time stre...

When an ad hoc network is to be used in a disaster situation, it is likely that emergency information will be broadcast by voice streaming from a small number of nodes. Conventionally, simple flooding (SF) has been used as a method of broadcasting streams to the entire network. However, if SF is applied to information flows in which packets are generated at a high rate, as is the case with voic...

P2P computing offers a new interesting field for security researchers. Being highly distributed and lacking centralised, trusted entities for bootstrapping security mechanisms, these systems demand novel approaches for decentralised security solutions. Recently, a new class of P2P-applications has arisen: P2P-based voice and video streaming systems. The properties of these novel applications im...

This paper proposes an efficient approach for the identification of the predominant voice from polyphonic musical audio. The algorithm implements an auditory streaming model which builds upon tone objects and salient pitches. The formation of voices is based on the regular update of the frequency and the magnitude of so called streaming agents, which aim at salient tones or pitches close to the...

Voice over IP (VoIP) is rapidly changing the way we use the telephone for voice communications. The term "Voice over IP" defines the transport of VoIP‐based networks, including the signaling and streaming protocols as well as describing the codecs. VoIP is widely used by all kinds of consumers ranging from computer enthusiasts who are excited to get free long‐distance calls over the Internet to...

Large scale e-Research environments face classical distributed challenges: performance, heterogeneous equipment and variable contexts. The users of such infrastructures want to benefit from full interactive environments based on multimedia streams (voice, video, virtual reality) which are difficult to design and support on a large scale basis. In this paper, we present a new approach to support...

Abstract—Voice over Internet Protocol (VoIP) may provide good services through Mobile Ad hoc Networks (MANets) platform. It may cover many application scenarios range from safety to comfort related services. However, these networks introduce many challenges for supporting voice with QoS requirements. In this study, we take the first step in addressing the practical issues related to deploying v...

IIn this paper, we have successfully implemented a seamless handoff between heterogeneous networks to achieve a fast voice/video over IP (V oIP ) with Partially Reliable Stream Control Transport Protocol (PR-SCTP) instead of TCP or UDP. In order to improve real-time video/voice streaming over IP, the conventional framework IHU has been remodeled as a new framework called SCTP-IHU that can simul...
