Reliable filecasting to vehicular users in wireless broadcast networks is a very challenging task, as an error-free transmission of the files is required. Reliability can be achieved by means of Forward Error Correction (FEC) and post-delivery file repair mechanisms. In this paper, we describe and compare the standardized FEC schemes in DVB-H (Digital Video Broadcast Handheld) at the link and a...

With the envisioned era of Internet of Things (IoTs), all aspects of Intelligent Transportation Systems (ITS) will be connected to improve transport safety, relieve traffic congestion, reduce air pollution, enhance the comfort of transportation and significantly reduce road accidents. In IoVs, regular exchange of current position, direction, velocity, etc., enables mobile vehicles to predict an...

In this paper, we consider the communications involved by the execution of a complex application, deployed on a heterogeneous “grid” platform. Such applications extensively use macro-communication schemes, for example to broadcast data items. Rather than aiming at minimizing the execution time of a single broadcast, we focus on the steady-state operation. We assume that there is a large number ...

Cooperative vehicle safety (CVS) systems are a key application of intelligent transportation systems. In CVS systems, vehicles periodically broadcast their information, e.g., position, speed, and braking status. In this paper, we theoretically analyze the performance of vehicle-to-vehicle (V2V) broadcast communications at an intersection and provide tractable formulae of performance metrics to ...

We consider the problem of transmission of information sources with memory over a broadcast channel. This is motivated by the practical application of the design of audiovisual broadcast systems for digital TV/digital radio. Using a parallel Gaussian source model and an additive white Gaussian noise broadcast channel model, we consider the problem of information source transmission with the goa...

Recently, various unicast routing protocols have been proposed to deliver measured data from the sensor node to the sink node within the predetermined deadline in wireless sensor networks. In parallel with their approaches, some applications demand the specific service, which is based on broadcast to all nodes within the deadline, the feasible real-time traffic model and improvements in energy ...

Broadcast infrastructure systems—such as servers, switchers, head-end encoders, and specialty studio displays—support a multitude of input image formats, and commonly require images to be converted to high definition (HD) or a different resolution before they can be stored, encoded, or displayed. While specialized ASSPs have addressed this market with varying degrees of success, the challenge h...

An analysis of multiple criteria decision support systems and facilities management web-based automation applications that were developed by researchers from various countries assisted the authors to create their own Multiple Criteria Decision Support Web-Based System for Facilities Management (DSS-FM). DSS-FM differs from others in its use of new multiple criteria analysis methods as were deve...
