The high levels of urban traffic is becoming a main concern in our societies, generating problems such as excessive fuel consumption, CO2 emissions. Recently, Intelligent Trans-portation Systems (ITS) have emerged as a way to mitigate these problems. However, traffic analysis, improvement typically rely on simulations, which should be as realistic as possible. Meeting this requirement can be complex...
The Delay Tolerant Networks (DTN) approach is considered the best strategy to address the specific issues of the VANETs, namely high mobility, variable node density or frequent radio obstacles. Several protocols have been proposed for DTNs, being the epidemic routing (and variations of it) the most representative protocol. Nevertheless, the availability of navigation systems, thanks to which each...
In recent years, new architectures and technologies have been proposed for Vehicular ad hoc networks (VANETs).However, the experiments to validate these proposals tend to overlook the most important and representative factors. Moreover, the scenarios simulated tend to be very simplistic (highways or Manhattan-based layouts), which could seriously affect the validity of the obtained results. In this...
