Vehicular networks experience a number of unique challenges due to the high mobility of vehicles and highly dynamic network topology, short contact durations, disruption intermittent connectivity, significant loss rates, node density, and frequent network fragmentation. All these issues have a profound impact on routing strategies in these networks. This paper gives an insight about available solutions on relat...
Vehicular Delay-Tolerant Network (VDTN) is a new disruptive network architecture where vehicles act as the communication infrastructure. VDTN follows a layered architecture based on control and data planes separation, and positioning the bundle layer under the network layer. VDTN furnishes low-cost asynchronous communications coping with intermittent and sparse connectivity, variable delays and even no end-to-e...
Desde os anos oitenta que os avanços das ciências básicas e das ciências da engenharia têm dado um impulso sem precedentes à investigação médica, o que criou as condições para a afirmação da Engenharia Biomédica como ramo autónomo da Engenharia. Este novo ramo da Engenharia impôs-se em domínios que incluem a imagiologia biomédica, a bioinformática, a biotecnologia, a biomecânica, os biomateriais, a engenharia d...
