Abstract: Vehicular ad-hoc networks with inter-vehicular communications are a prospective technology which contributes to safer and more efficient roads and offers information and entertainment services to mobile users. Since large real-world testbeds are not feasible, research on vehicular ad-hoc networks depends mainly on simulations. Therefore, it is crucial that realistic mobility models are employed. We propose a generic and modular mobility simulation framework (GMSF). GMSF simplifies the design of new mobility models and their evaluation. Besides, new functionalities can be easily added. GMSF also propose new vehicular mobility models, GIS-based mobility models. These models are based on highly detailed road maps from a geographic information system (GIS) and realistic microscopic behaviors (car-following and traffic lights management). We perform an extensive comparison of our new GIS-based mobility models with popular mobility models (Random Waypoint, Manhattan) and realistic vehicular traces from a proprietary traffic simulator. Our findings leverages important issues the networking community still has to address.

SpotME If You Can: Randomized Responses for Location Obfuscation on Mobile Phones
Daniele Quercia,Ilias Leontiadis,Liam McNamara,Cecilia Mascolo,Jon Crowcroft +4 more
- 20 Jun 2011
TL;DR: This work proposes a piece of software (Spot Me) that can run on a mobile phone and is able to estimate the number of people in geographic locations in a privacy-preserving way and finds that erroneous locations have little effect on the estimations, yet they guarantee that users cannot be localized with high probability.
Evaluating Location Privacy in Vehicular Communications and Applications
TL;DR: This paper defines continuous network location privacy, and presents KDT-anonymity, which is a composite metric including average anonymity set size, i.e., K, average distance deviation, and anonymity duration, which derives formulas to calculate theoretical values of K, D, and T.

Congested traffic states in empirical observations and microscopic simulations
TL;DR: It is shown that the results of the microscopic model can be understood by formulating the theoretical phase diagram for bottlenecks in a more general way, and a local drop of the road capacity induced by parameter variations has essentially the same effect as an on-ramp.

TL;DR: A series of simulation models that account for street layout, traffic rules, multilane roads, acceleration-deceleration, and RF attenuation due to obstacles found that the delivery ratio and packet delays in VANETs are more sensitive to the clustering effect of vehicles at intersections and their acceleration/ deceleration.
