MDDV: a mobility-centric data dissemination algorithm for vehicular networks
MDDV is designed to exploit vehicle mobility for data dissemination, and combines the idea of opportunistic forwarding, trajectory based forwarding and geographical forwarding, and develops a generic mobile computing approach for designing localized algorithms in vehicular networks. Expand
Large-scale network simulation: how big? how fast?
Results from a recent performance study are presented concerning large-scale network simulation on a variety of platforms ranging from workstations to cluster computers to supercomputers, and an approach to realizing scalable network simulations that leverages existing sequential simulation models and software is described.

Spatial Propagation of Information in Vehicular Networks
Analytical models to study the spatial propagation of information in a highly mobile v2v ad hoc network are presented and show that information propagation depends on some vehicle traffic characteristics, e.g., vehicle density, average vehicle speed, and relative vehicle movement. Expand
A Cluster-Head Selection and Update Algorithm for Ad Hoc Networks
A novel cluster-head selection and update algorithm "Type-based Cluster-forming Algorithm (TCA)" is proposed, which outperforms both the lowest node ID (LID) and the Weighted Clustering AlgorithmExpand
Analytical models for information propagation in vehicle-to-vehicle networks
There has been increasing interest in information infrastructures based on vehicle-to-vehicle communications. Proposed network architectures have unique characteristics that distinguish them fromExpand
Efficiency of Simulated Vehicle-to-Vehicle Message Propagation in Atlanta, Georgia, I-75 Corridor
Exploitation of in-vehicle information technology (e.g., mobile computing and wireless communications) in surface transportation systems is a clearly emerging trend. Equipping vehicles withExpand
Numerical Conditioning Problems and Solutions for Nonparametric i.i.d. Statistical Active Contours
This paper proposes an active contour model based on nonparametric independent and identically distributed (i.i.d.) statistics of the image that can segment an image without any a priori information about the intensity distributions of the region of interest or the background, and introduces the notion of conditioning ratio to discuss this improved numerical behavior.

Interference-Based Capacity Analysis for Vehicular Ad Hoc Networks
An interference-based capacity analysis is carried out for the abstracted 1-dimensional VANETs scenario for the worst-case interfering scenario, which finally leads to the stochastic characteristics for both the link and network capacity. Expand
