TLDR
A new, realistic model of node motion based on the movement of vehicles on real street maps is presented, which is compared with the Random Waypoint mobility model, the most widely used mobility model.Abstract:
Without realistic modeling of node mobility, simulation evaluation of performance of mobile ad hoc networks may not correlate well with performance in a real deployment. In this work, we present a new, realistic model of node motion based on the movement of vehicles on real street maps. Our model can be used with the ns-2 network simulator. We compare our model with the Random Waypoint mobility model, the most widely used mobility model. Results show that, in many ways, the Random Waypoint mobility model is a good approximation for simulating the motion of vehicles on a road, but there are situations in which our new model is better suited.read more

Rapid Generation of Realistic Mobility Models for VANET
TL;DR: This work introduces a tool MOVE, a tool that allows users to rapidly generate realistic mobility models for VANET simulations and shows that the simulation results obtained when nodes moving according to a realistic mobility model is significantly different from that of the commonly used random waypoint model.

Eviction of Misbehaving and Faulty Nodes in Vehicular Networks
TL;DR: This paper proposes protocols, as components of a framework, for the identification and local containment of misbehaving or faulty nodes, and then for their eviction from the system, and shows that the distributed approach to contain nodes and contribute to their eviction is efficiently feasible and achieves a sufficient level of robustness.

Study of a bus-based disruption-tolerant network: mobility modeling and impact on routing
TL;DR: The study of traces taken from UMass DieselNet, a Disruption-Tolerant Network consisting of WiFi nodes attached to buses, finds that the all-bus-pairs aggregated inter-contact times show no discernible pattern, and suggests the importance in choosing the right level of model granularity when modeling mobility-related measures such as inter- contact times in DTNs.
CARAVAN: Providing Location Privacy for VANET
TL;DR: This paper proposes a location privacy scheme called CARAVAN, and evaluates the privacy enhancement achieved under some existing standard constraints of VANET applications, and in the presence of a global adversary.

Dynamic Source Routing in Ad Hoc Wireless Networks.
David B. Johnson,David A. Maltz +1 more
TL;DR: In this article, the authors present a protocol for routing in ad hoc networks that uses dynamic source routing, which adapts quickly to routing changes when host movement is frequent, yet requires little or no overhead during periods in which hosts move less frequently.
