Coding techniques for multicasting
We study some fundamental limits of multicasting in wireless systems and propose practical architectures that perform close to these limits. In Chapter 2, we study the scenario in which one transmitter with multiple antennas distributes a common message to a large number of users. For a system with …

Application Aware Multicasting in VPLS Networks.
Enterprise customer demand for business class Ethernet service offerings, over the years, has steadily increased. More so, the demand for high throughput coupled with efficient utilization of the available bandwidth. This has driven service providers to seek more reliable means of delivering …

Failsafe routing and multicasting in dynamic internets
… developing reliable procedures for routing and multicasting in networks that are subject to frequent changes in traffic load and topology. The routing procedures described in this thesis continue to reconstruct routes and forward messages correctly in the face of such changes, but they do not …

Key Management Techniques for Dynamic Secure Multicasting
Most of the Internet applications today require multicasting. For example, software updates, multimedia content distribution, interacting gaming and stock data distribution require multicast services. All of these applications require privacy and authenticity of the participants. Most of the …

Enhanced communication services for many-to-many multicasting using XTP
… of the various aspects involving reliable multicasting. XTP, one of the well-known transport protocols, provides a toolkit of mechanisms over which the user may build the protocol he so desires. It has been observed that the multipoint-to-multipoint mechanisms as described in the appendix …

Throughput analysis of input-queued packet switches : multicasting and speedup
The widespread use of new applications such as voice/video streaming, the WWW, and the MBone has caused an increased demand for bandwidth in the Internet. In response to this, Internet backbone speeds have increased to several gigabits/sec, thus causing packet switches and routers to become …

Multiplexing, scheduling, and multicasting strategies for antenna arrays in wireless networks
… of the data streams. Finally, we address the multicasting of common data streams in terms of opportunities for reduced redundancy as well as the conflicting objectives inherent in sending to multiple receivers. Our channel-aware extensions of space-time codes for multicasting gain several dB …

Study of architecture and protocols for reliable multicasting in packet switching networks
… is mainly a transport layer task, reliable group multicasting depends on routing architectures as well. This dissertation covers issues of both network and transport layers. Two routing architectures, tree and ring, are surveyed with a comparative study of their routing costs and impact to upper …

Topology-aware multicasting in phased mobile ad hoc networks for e-learning
This thesis presents an adaptive multicast routing protocol called a Topology-Aware Polymorphic Multicast Routing Protocol (TAPMRP) for use in Mobile Ad hoc NETworks (MANETs). TAPMRP is proposed to serve E-Learning classroom (ELC) environments, which are generally characterised by minimal topology …

Qos-Aware Service Management for Internet-Scale Distributed Applications
… resources, by proposing a special type of multicasting---service-added multicasting. Resource sharing is further maximized as we integrate traditional data multicasting into service multicasting. We call the integrated solution hybrid multicasting.

PSEUDO DIAMETER - A NOVEL CONCEPT IN DESIGNING HIGHLY BANDWIDTH EFFICIENT MULTICAST ROUTING PROTOCOLS
Multicasting is preferred over multiple unicasts from the viewpoint of better utilization of one of the most important network resources, namely network bandwidth. Multicasting can be done in two different ways: source based tree approach and shared tree approach. This research focuses on improving …

Atomic Broadcast in Heterogeneous Distributed Systems
… protocols renders itself inadequate for multicasting in interconnected LANs. The progress in development methodology for efficient and robust LAN software has not been matched by similar advances for WANs. A high-latency, a lower bandwidth, a higher probability of partitions, and a …

Anonymous Multicast Communication for Wireless Networks Using Layered Encryption and Hashing
… and more sensor network applications require multicasting to multiple base nodes, and anonymity of the base nodes have become an important aspect of communication in wireless sensor networks. Limited capabilities of the sensor node and a need of multicasting make the issue of anonymity more …

Multiuser Diversity Management for Multicast/Broadcast Services in 5G and Beyond Networks
… (QoS)/quality of experience (QoE) requirements, multicasting over millimeter-wave (mmWave) and sub-Terahertz (THz) frequencies, and handling complex mobility behaviors. In the broad problem space around these three significant challenges, we focus on the specific research problems of effectively …

Optimized Network Coding for Wireline and Aref Networks
… coding in wireless scenarios, we investigate multicasting in Aref networks. These networks do not capture interference, but they do incorporate deterministic broadcasting. We characterize the multicast capacity of Aref networks, the achievability of which is shown using an ensemble of random …

Optimising Networks For Ultra-High Definition Video
… systems. Transcoders and application layer multicasting (ALM) can reduce traffic in a video delivery system, but they are limited due to the static nature of their implementations. To overcome the restrictions of current static video delivery systems, an OpenFlow based migration system is …
