We address the worst-user bottleneck of wireless coded caching, which is known to severely diminish cache-aided multicasting gains due fundamental worst-channel limitation multicasting. consider quasi-static Rayleigh fading Broadcast Channel, for we first show that effective caching gain standard XOR-based coded-caching scheme completely vanishes in low signal-to-noise ratio (SNR) regime. Then,...

In this paper we address the problem of multicasting in military ad hoc networks from the viewpoint of energy efficiency. We discuss the impact of the wireless medium on the multicasting problem and the fundamental trade-offs that arise, and we propose and evaluate several algorithms for defining multicast trees when transceiver resources are limited. The algorithms select the relay nodes and t...

Multicasting is the transmission of packets to a group of zero or more hosts identi ed by a single destination address Multicasting is intended for group oriented computing Typically the members of a host group is dynamic that is hosts may join and leave groups at any time There is no restriction on the location or number of members in a host group A host may be a member of more than one group ...

In this paper we address the problem of providing transparent, reliable, and efficient network-level multicasting in wormhole LANs. We describe some alternatives for achieving deadlock-free multicasting using fast buffer reservation techniques at the host interface level. Tradeoffs involving complexity and performance of various solutions are discussed, and are illustrated using simulation resu...

Mobile TV is a new interesting area in the telecommunication industry. The technology for sending live video to mobile clients is characterized by relatively low CPU processing power, low network resources and low display resolution. In this paper we discuss a solution to all of these problems by using application layer multicasting. This can significantly reduce the needed bitrate and required...

In this paper, we investigate simultaneous wireless power transfer and secure multicasting via cooperative decode-and-forward (DF) relays in the presence of multiple energy receivers and eavesdroppers. Two scenarios are considered under a total power budget: maximizing the minimum harvested energy among the energy receivers under a multicast secrecy rate constraint; and maximizing the multicast...

In the terrestrial digital TV systems broadcasting is employed, meaning that all TV programs are sent over all transmitters, also where there are no viewers. This is inefficient utilization of spectrum and transmitter equipment. Applying interactive multicasting over DV approach that would substantially reduce the spect to deliver a certain amount of TV programs be achieved by Dynamic single-fr...
