Adaptive Multicast Routing Protocol Based on Reinforcement Learning
Current Mobile Ad-hoc Network (MANET) multicasting approaches either suffer from low Packet Delivery Ratio (PDR) or high overhead. These methods rely on metrics like hop count to find the optimal path to the destination. Once the path is selected, all packets are sent over the same path as long as …

The application of network coding to multicast routing in wireless networks
… application of network coding and opportunistic routing to improve the performance of multicast flows in wireless networks. Network coding allows routers to randomly mix packets before forwarding them. This randomness ensures that routers that hear the same transmission are unlikely to forward …

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 …

An All-to-All Multicast Routing Protocol in a Wireless Ad-Hoc Network to Improve Channel Utilization
… become more and more popular. Several different multicasting schemes for this type of network have been developed. But most of them are targeting a situation where the total number of senders is much less than the total number of receivers. This thesis analyzes different wireless communication …

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 …

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 …

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 …

Saturation routing for asynchronous transfer mode (ATM) networks
… of this thesis is to show that saturation routing, often in the past considered inefficient, can in fact be a viable approach to use in many important applications and services over an Asynchronous Transfer Mode (ATM) network. For other applications and services, a hybrid approach (one that …

A new framework for minimising handover in multicast mobility
… the efficient delivery of multimedia messages is multicast delivery.Multicast services do, however, introduce challenges within the network when the recipients of the service are moving. Powerful multicast routing protocols are designed for static client IP addresses. Hence, when the mobile node …
