In this study, we describe an effective video communication framework for the wireless transmission of H.264/AVC medical ultrasound video over mobile WiMAX networks. Medical ultrasound video is encoded using diagnostically driven, error resilient encoding, where quantization levels are varied as a function of the diagnostic significance of each image(More)
Vehicular Ad Hoc Networks (VANETs) are emerging as the preferred network design for intelligent transportation systems and are envisioned to be useful in road safety and commercial applications. A significant issue in VANETs is the design of an effective broadcast scheme which can facilitate the fast and reliable dissemination of critical safety messages to(More)
Demand on video traffic over mobile network is increasing in year on year basis, wireless link capacity cannot satisfying the traffic requirement. The difference in the traffic demand and the link capacity with varying link conditions results in poor quality of videos such as intermittent disruptions and long buffering time over mobile networks. Due to such(More)
It is known that probabilistic flooding in mobile ad hoc networks is characterized by phase transition phenomena [1], similar to the ones observed in the context of random graphs and percolation theory [2], which suggest the existence of a critical rebroadcast probability value beyond which high reachability is achieved with high probability. The phenomenon(More)
A number of probabilistic flooding schemes have been recently considered in VANETs to address problems of information dissemination in safety applications. The design approach has so far been simulative, a method which does not guarantee that the derived protocols will work when the simulation settings are violated in practice. In this paper, motivated by(More)
