Content Distribution in Overlay Multicast
… bandwidth consumption compared to the ideal IP-multicast-based solutions. Second, regarding the high throughput challenge, using multi-commodity flow theory, we establish the theoretical foundation for multi-tree overlay multicast. Based on this foundation, we propose a series of algorithms, …

Cooperative multicast in wireless networks
… The novel element is wireless, cooperative multicast that could be the basis for a new broadcast distribution paradigm. In the first part of the thesis,. we investigate efficient ways to construct multicast trees by exploring cooperation among local radio nodes to increase throughput and …

Reliable peer-to peer multicast streaming
P2P is increasingly gaining its popularity for streaming multimedia contents. The architecture of streaming has shifted from traditional client server architecture to P2P architecture. Although it is scalable and robust it faces its own challenges and problems such as churn. In tree topology …

Multicast Services for Multimedia Collaborative Applications
<p>This work aims at providing multicast services for multimedia collaborative applications over large inter-networks such as the Internet. Multimedia collaborative applications are typically of small group size, slow group membership dynamics, and awareness of participants' identities and …

Multicast Video Transport overiPOINT ATM Testbed
In addition to the development of Video Server and Video Client applications, we have designed and implemented a novel ATM Network Video Interface Module. This module receives ATM cells from an ATM switch port, performs all the re-assembly functions and extracts video data from the adaptation layer …

Multicast Support for Heterogeneous Packet Flows
In order to speedily deploy these new multicast services, this dissertation promotes the idea of a virtual overlay architecture, which provides a common framework for both IRMA and MHPF. In this framework, a virtual network of specialized multicast servers, i.e. IRMA servers or MHPF servers, is …

Secure multicast for power grid communications
Secure multicast for power grid systems faces a number of challenges like complex and error-prone group configuration, inefficient group key management, real-time challenges to existing security protocols and the balance among correctness, efficiency, feasibility and cost. We propose an …

Extensions for Multicast in Mobile Ad-hoc Networks (XMMAN): The Reduction of Data Overhead in Wireless Multicast Trees
… protocols have been explored, research involving multicast protocols has been limited. Existing multicast algorithms attempt to reduce routing overhead, but few, if any, attempt to reduce data overhead. The broadcast nature of wireless communication creates a unique environment in which overlaps …

Virtualization of multicast services in WiMAX networks
Multicast service is one of the methods used to efficiently manage bandwidth when sending multimedia content. To improve bandwidth utilisation, virtualization is often invoked because of its additional features such as bandwidth sharing and support of services that require high volumes of …

Simplified random network codes for multicast networks
… Network coding is particularly attractive for multicast. Building on the work done on random linear network codes, we develop a constrained, simplified code construction suitable for multicast in wireless networks. We analyze bounds on sufficient code size and code success probability via an …

RP relocation in protocol independent multicast-sparse mode
Protocol Independent Multicast - Sparse Mode is the most widely used multicast routing architecture. It builds a shared distribution tree centered at a Rendezvous Point and then builds source-specific trees for those sources whose data traffic warrants it. Current implementations of the protocol …
