Resumen

Denial Of Service  en VANETs un problema o una fatalidad

Las redes inalámbricas y móviles tienen muchas ventajas como una fácil implementación, la movilidad del usuario y proporciona acceso a la red a los usuarios, independientemente de su ubicación.

Los problemas más críticos que se presentan en estas redes están en las asignaciones de recursos como el ancho de banda es limitado, la propagación (de múltiples rutas, fading, distorsión) y la seguridad ya que las comunicaciones se transmiten por ondas de radio.

En las nuevas arquitecturas paralelas / tecnologías se han convertido en Redes Vehiculares y de Internet de las Cosas ( IoT) .

En esta conferencia, se presentan cuestiones acerca de la disponibilidad de un problema en esas redes y la arquitectura, centrado en  redes vehiculares, se presentarán asimismo algunos trabajos realizados y otras obras para mejorar la seguridad en esos sistemas.

Herramientas estocásticos utilizadas para mejorar y / o para evaluar la capa MAC en las redes inalámbricas

 Las redes inalámbricas y móviles tienen muchas ventajas como una fácil implementación, la movilidad del usuario y proporcionan acceso a la red a los usuarios, independientemente de su ubicación.

Los problemas más críticos que se presentan en estas redes están en las asignaciones de recursos como el ancho de banda es limitado, la propagación (de múltiples rutas, fading, distorsión) y la seguridad ya que las comunicaciones se transmiten por ondas de radio.

En esta conferencia se presentan varios trabajos realizados para modelar / Mejorar la calidad de servicio en redes inalámbricas.

Tres métodos diferentes se presentarán en esta conferencia.

En la primera parte se presenta un nuevo modelo basado en cadenas de Markov para modelar las diferentes clases de servicio definidas en la norma IEEE 802.16.

La segunda parte se presenta un nuevo AC que se ha definido para el IEEE 802.16 y evaluado utilizando procesos estocásticos de Autómatas Networks. Finalmente se presenta una comparación estocástica para el control de admisión en redes inalámbricas que utilizan estándar IEEE 802.11.
