Many protocols and applications need a discovery mechanism to enable a given client node to locate one or several specific nodes involved in the same communication. However, there is no protocol ready to fulfill this service at the network layer. Every protocol usually implements its own solution. In particular, multicast protocols often use a search technique called expanding ring search. This...

This paper considers the downlink precoding for physical layer multicasting in massive multipleinput-multiple-output (MIMO) systems. We study the max-min fairness (MMF) problem, where channel state information (CSI) at the transmitter is used to design precoding vectors that maximize the minimum spectral efficiency (SE) of the system, given fixed power budgets for uplink training and downlink t...

Optical technology gains extensive attention and ever increasing improvement because of the huge amount of network traffic caused by the growing number of internet users and their rising demands. However, with wavelength division multiplexing (WDM), it is easier to take the advantage of optical networks and optical burst switching (OBS) and to construct WDM networks with low delay rates and bet...

Multicast network traac is information with one source node, but many destination nodes. Rather than setting up individual connections between the source node and each destination node, or broadcasting the information to the entire network, multicasting eeciently exploits link capacity by allowing the source node to transmit a small number of copies of the information to mutually-exclusive grou...

Title of Dissertation: Error Control for Multicasting in Satellite and Hybrid Communication Networks Daniel E. Friedman, Doctor of Philosophy, 2000 Dissertation directed by: Professor Anthony Ephremides Department of Electrical Engineering A problem inherent in ARQ multicasting over a broadcast channel is that a retransmission typically benefits only a minority of destinations while all others ...

tolerant networks are a class of emerging networks that experience frequent and long-duration partitions. These networks have a variety of applications in situations such as crisis environments and deep-space communication. In this paper, we study the problem of multicasting in TNs. Multicast supports the distribution of data to a group of users, a service needed for many potential TN applicati...

The academic and research communities are showing significant interest in the modern highly promising technology of wireless mesh networks (WMNs) due to their low-cost deployment, self-configuration, self-organization, robustness, scalability, reliable service coverage. Multicasting is a broadcast technique which communication started by an individual user shared one or multiple groups destinat...
