Multi-hop wireless broadcast is a critical component in ad-hoc wireless networks. Vehicular Ad-hoc Networks (VANET) in particular utilize broadcast as a primary communication mechanism in many applications. Because of their simplicity, statistical broadcasting methods have been adopted in several VANET broadcasting schemes. However, it is difficult to develop analytical models of these protocols, therefore no results are known proving reachability characteristics for them like there are for topological protocols such as Multi-Point Relaying (MPR).Therefore, we describe a technique to design statistical broadcasting protocols with threshold curves that give a target level of reachability with a desired confidence level. We model the distribution of reachability in a statistical protocol using the Pareto distribution which is then used to estimate the confidence with which a given threshold value will provide reachability exceeding the application-specific target.We apply this technique to develop a protocol based on the distance-to-mean method that meets a target reachability of 99% with 95% confidence. Evaluations using JiST/SWANS verify the protocol's performance.

“…In [21] authors find that protocols based on topology, such as Advanced Adaptive Gossiping, and Multi-Point Relaying tend to have a decreasing retransmission efficiency as the node density increases, indicating they scale poorly with node density. Stochastic broadcast and the distance methods have thresholds that are set directly by node density.…”

From a distributed system approach, the computation of events locally was more efficient than the transmission to a central host, because this can significantly reduce the number of data transmissions by up to 90% [21].…”

This paper analyzes how street-level traffic data affects routing in VANETs applications. First, we offer a general review about which protocols and techniques would fit best for VANET applications. We selected five main technical aspects (Transmission, Routing, Quality of Service, Security and Location) that we consider are differential aspects of VANETs from current Ad-Hoc Networks. Second, the paper analyzes how to configure each technical aspect according to the goal of a wide range of VANET applications. Third, we look at the routing aspect in depth, specifically focusing on how vehicle density affects routing, which protocols are the best option when there is a high/low density, etc. Finally, this research implements a sensor technology, based on an acoustics sensor that has been deployed around the city of Xalapa in México, to obtain reliable information on the real-time density of vehicles. The levels of density were discretized and the obtained data samples were used to feed a traffic simulator, which allowed us to obtain a global picture of the density of the central area of the city. According to the specific levels of vehicle density at a specific moment and place, VANET applications may adapt the routing protocol in a real-time way.

“…En VANET tenemos que un Broadcast [6][4] inalámbrico Multi-hop, donde dichas redes exhiben situaciones de muy altas densidades de nodos, así la importancia que los protocolos broadcast puedan dar soporte con altas densidades [18], pero al menor costo con un óptimo despliegue de la infraestructura. Por lo tanto, la entrega de la información mediante multi-hops [19][20] [13] requiere de nodos intermedios que permiten llevar la comunicación hasta una radio base celular que se encargue de la última milla con el objeto de recolección en la oficina central de gestión y control, así tenemos que en VANET [9] dichos nodos también pueden ser vehículos similar a esto tenemos que a nivel de AMI los nodos o medidores inteligentes se interconectan entre sí con nodos de otras viviendas, esta fusión hace un esquema heterogéneo y a la vez altamente denso ya que la información es recolectada desde varias fuentes.…”

This paper presents an optimal deployment model on Universal Data Aggregation Points (UDAP); therefore, ideal for receive information of Vehicular Ad-Hoc Networks (VANET), and for the Advanced Metering Infrastructure (AMI), based on FiWi networks. The optimal dimensioning and scalability of fiber optic networks, and the candidates sites for each UDAP are considered in this work, so that the cost for infrastructure of communications will be acceptable, but considering reliability, efficiency, and with dynamic maintenance for long term. On the other hand, is possible to agglutinate the data of VANET and AMI using wireless networks in each UDAP; furthermore, we propose generate a link between UDAP with the minimum deployment of fiber optic links througth an ILP model and an algorithm named Clustering Location Deployment Allocation Cost-CLDAC. For this work, each UDAP considered different technologies of communications such as: WiFi, IEEE 802.15.4g, WiMax. Thus, this situation enables additional services to VANET and AMI are considering in the future, due to the exponential increase of wireless sensors used in different applications.
