چکیده

In this paper we present work in progress on extending multimedia conferencing standards to scalable, mobile multimedia group support based on SIP initiated Source Specific IP Multicast. We propose extensions of SIP for negotiating SSM sessions. SIP protocol specifications and semantics are compatibly extended without adding new SIPmethods. We will introduce a multimedia communication software with distributed architecture as implementation reference. The software is built on a scalable video codec adaptive to heterogeneous network capacities.

Scalable distributed conference control in heterogeneous peer-to-peer scenarios with SIP

An increasing number of popular conferencing applications operate in a lightweight, infrastructure-independent ad hoc fashion and extend into the mobile realm. These P2P-type systems raise the demand for scalable, adaptive self organization of conferencing in a standard-compliant way. This paper addresses the challenge of distributed conference management with SIP and makes the following two co...

Adaptive P2P Caching for Video Broadcasting over Wireless Ad Hoc Network

With the advance of science and technology, wireless networks are becoming a significant part of today’s access networks. Ad hoc networks are wireless mobile networks without an infrastructure. Recently more and more multimedia services are applied to ad hoc networks. Because of the problem of the mobility, it always makes the interruption of video packets transmission, which causes the worse q...

SP-driven QoS provision Mechanism for Real-Time Multimedia Streaming over P2P Networks using Admission Control

Enabling Quality of Service (QoS) for End-to-End real-time multimedia content delivery across heterogeneous P2P networks is challenging but vital for the efficient service provision. In this paper, we present an admission control based for the real-time multimedia streaming over Service Provider (SP) driven peer-to-Peer (P2P) networks. SP-driven P2P networks are the P2P networks where network p...

Effective Video Streaming using Mesh P2P with MDC over MANETs

Peer-to-Peer (P2P) streaming and Mobile Ad hoc Networks (MANETs) have turned out to be two of the most active research areas for pervasive computing. These areas were developed independently of each other with the result that there is insufficient verification of whether the P2P distribution paradigm and specifically P2P real-time video streaming would work on MANETs. In this paper, we demonstr...

Architecture and Performance Evaluation of MP2P

A novel mobile peer-to-peer (MP2P) in cellular networks is presented in this paper. The proposed architecture is based on Session Initiation Protocol (SIP) that is part of the IP Multimedia Subsystem (IMS) in the third-generation mobile cellular networks. In this architecture, P2P control messages are transported in SIP messages, so called P2PoverSIP. By way of SIP, the operators can have contr...
