Video on Demand (VOD) system is an electronic video rental system where the clients have the ability to request and view the video at any time, which makes the VOD to become an important technology with many applications. Numerous periodic VOD broadcasting protocols have been proposed to support a large number of receivers. Broadcasting is an efficient transmission scheme which provides on-dema...

Because adaptability greatly improves the performance of a broadcast protocol, we identify three ways in which machine learning can be applied to broadcasting in a mobile ad hoc network (MANET). We chose broadcasting because it functions as a foundation of MANET communication. Unicast, multicast, and geocast protocols utilize broadcasting as a building block, providing important control and rou...

The broadcasting problem asks for the fastest way of transmitting a message to all nodes of a communication network. We consider the broadcasting problem in conflictaware multi-channel networks. These networks can be modeled as undirected graphs in which each edge is labeled with a set of available channels to transmit data between its endpoints. Each node can send and receive data through any ...

Broadcasting in processor networks means disseminating a single piece of information, which is originally known only at some nodes, to all members of the network. The goal is to inform everybody using as few rounds as possible, that is minimize the broadcast time. Given a graph and a subset of nodes, the sources, the problem to determine its specific broadcast time, or more generally to find a ...

In the beginning the information is available only at some sources of a given network. The aim is to inform all nodes of the given network. Therefore, every node can inform its neighborhood sequentially and newly informed nodes can proceed in parallel within their neighborhoods. The process of informing one node needs one time unit. The broadcasting problem is to compute the minimum length of s...

This chapter studies the cooperative broadcasting in wireless networks. We especially focus on multistage cooperative broadcasting in which the message from a source node is relayed by multiple groups of cooperating nodes. Interestingly, group transmissions become beneficial in the case of broadcasting as opposed to the case in traditional networks where receptions from different transmitters a...

Wyner’s wiretap channel is extended to parallel broadcast channels and fading channels with multiple receivers. In the first part of the paper, we consider the setup of parallel broadcast channels with one sender, multiple intended receivers, and one eavesdropper. We study the situations where the sender broadcasts either a common message or independent messages to the intended receivers. We de...

We consider deterministic broadcasting in geometric radio networks (GRN) whose nodes know only a limited part of the network. Nodes of a GRN are situated in the plane and each of them is equipped with a transmitter of some range r . A signal from this node can reach all nodes at distance at most r from it but if a node u is situated within the range of two nodes transmitting simultaneously, the...

Broadcasting is an essential operation for Wireless Ad Hoc Networks to perform routing path discovery, and it has become the predominant technology for message dissemination in Vehicular Ad Hoc Networks (VANETs). In the reactive routing schemes of wireless ad hoc network, Routing Request (RREQ) packets are broadcast from the source, and once received the destination traces back the broadcasting...
