Building Transmission Backbone for Highway Vehicular Networks: Framework and Analysis

Connectivity of Highway Vehicular Networks

A realistic simulation framework for vehicular networks

Research in Vehicular Networks (VNs) has found in simulation the most useful method to test new algorithms and techniques. This is mainly due to the high cost of deploying such systems in real scenarios. When simulating vehicular environments, two different issues must be addressed: mobility and wireless communications. Regarding mobility, several mobility pattern generators have been proposed ...

A Probabilistic Framework for Highway Safety Analysis '

Brownian motion is used to model the uncertainty in the motion of cars on a highway. The probability of collision of two adjacent cars within a fixed horizon is calculated and its implications are discussed. Moreover, the probability of collision in the presence of emergency braking is also obtained by modeling the occurrence of emergency braking as a Poisson process.

Safety Message Transmission in Vehicular Communication Networks

Emerging vehicular safety applications require low latency communications and reliable packet dissemination for life saving safety messages. Significant developments have taken place over the past few years. IEEE WAVE and ISO CALM have been developed as international standards for ITS applications. Both WAVE and CALM support multichannel operations and use CSMA/CA as channel access mechanism. W...

SAT: Building New Trust Architecture for Vehicular Networks

Establishing trust in vehicular networks is a critical but also difficult task. In this position paper, we present a new trust architecture and model -situation-aware trust (SAT) to address several important trust issues in vehicular networks that rely on the current Internet infrastructure. The new model addresses several important trust issues that we believe are essential to overcome the wea...
