Time critical and delay sensitive multimedia applications require more spectrum and transmission resources. With the provision of cognitive radios (CRs), the underutilized spectrum resources can be exploited to gain more bandwidth for the bandwidth hungry applications (multimedia applications). Cognitive radio networks (CRNs) also have the flexibility to adjust their transmission parameters acc...

This paper describes an enhanced automatic keyphrase extraction method applied to Broadcast News. The keyphrase extraction process is used to create a concept level for each news. On top of words resulting from a speech recognition system output and news indexation and it contributes to the generation of a tag/keyphrase cloud of the top news included in a Multimedia Monitoring Solution system f...

Over the past two decades, cable television has largely supplanted over-the-air broadcast as a TV distribution medium, at least in most urban and suburban areas. Several years ago, enterprising companies concluded that they could leverage the extremely wide bandwidth of cable TV systems required to deliver broadcast-quality television as a high-speed conduit for broadband data communications. T...

Today's world has been the world of media. Today can hardly find a place that people are far and separated from the media and media effects. Practices, knowledge, tastes, and many teachings of daily life of every human, somehow directly or indirectly will be affected by what the media has covered. This article attempts to focus on national media audience on one hand and satellite television net...

The IEEE 802.16 technology (WiMAX) is a better alternative to 3G or wireless LAN networks for providing last mile connectivity by radio link due to its high data rates, low cost of deployment and large coverage area and Ease of Use. With the IEEE 802.16e−2005 mobility amendment, WiMAX promises to address the ever-increasing demand for mobile high speed wireless data in fourth-generation (4G) ne...

The industrial Internet of Things (IoT) is aiming to interconnect humans, machines, materials, processes and services in a network. Wireless Sensor Network (WSN) comprises the less power consuming, light weight and effective Sensor Nodes (SNs) for higher network performance. Radio Frequency Identification (RFID) and sensor networks are both wireless technologies that provide limitless future po...
