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...

This paper introduces the Terrestrial Digital Video Broadcasting DVB-T, stating its innovative aspects and its major advantages for data broadcasting, particularly TV broadcasting. It also presents the experimental DVB-T network built up by Retevisión in the framework of the Spanish VIDITER project (Terrestrial Digital Video) and the European ACTS VALIDATE (Verification and launch of Integrated...

The graphical description techniques provided by UML-RT are significant aids in modeling aspects of structure and behavior in software architectures for reactive and embedded real-time systems. Here, we sketch an extension of UMLRT’s reach from binary communication to broadcasting. To that end, we introduce sequence diagrams tailored for capturing broadcasting scenarios. Furthermore, we describ...

This paper proposes an efficient network architecture to improve energy consumption in Wireless Sensor Networks (WSN). The proposed architecture uses a mobile data collector to a partitioned network. The mobile data collector moves to center of each logical partition after each decision period. The mobile data collector must declare its new location by packet broadcasting to all sensor node...

Our focus is on the study and development of efficient algorithms for the task of broadcasting within peer-to-peer (P2P) data distribution systems. The purpose of broadcasting is to completely distribute a target set of data pieces from a set of initial sources to all peers within the distribution system. Thus, findings from the study of the problem of broadcasting have useful implications for ...

We consider asynchronous deterministic broadcasting in radio networks. An execution of a broadcasting protocol is a series of events, each of which consists of simultaneous transmitting or delivering of messages. The aim is to transmit the source message to all nodes of the network. If two messages are delivered simultaneously to a node, a collision occurs and this node does not hear anything. ...
