Islam is a da'wah religion, so its adherents are required to always carry out da'wa activities in society. Da'wah can be carried various ways that do not conflict with Islamic teachings. One way through electronic mass media such as radio. This research field research, which collects data the systematic and comprehensive manner. So carrying this exploration, it requires creators go direc...

The paper considers broadcasting protocols in radio networks with known topology that are efficient in both time and energy. The radio network is modelled as an undirected graph G = (V,E) where |V | = n. It is assumed that during execution of the communication task every node in V is allowed to transmit at most once. Under this assumption it is shown that any radio broadcast protocol requires D...

The widely-studied radio network model [Chlamtac and Kutten, 1985] is a graph-based description that captures the inherent impact of collisions in wireless communication. In this model, the strong assumption is made that node v receives a message from a neighbor if and only if exactly one of its neighbors broadcasts. We relax this assumption by introducing a new noisy radio network model in whi...

Examination of the Quality of Service (QoS) at the end-user level of multimedia broadcasting systems is necessary in order to retain the overall performance and the user’s satisfaction level from the provided services, by revealing the possible weaknesses of the systems’ specifications. Accordingly we examine Digital Audio Broadcasting (DAB) system’s characteristics at the services level, with ...

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...

This paper presents several techniques for broadcasting multimedia data (audio and video) over the Internet. Internet broadcasting (also called webcasting) techniques have become very important in applications such as Internet (or Web) radio and television, realtime broadcasting of critical data (such as stock prices), distance learning, videoconferencing, and many others. We describe the curre...
