ABSTRACT
We present an analysis of and security extensions to the CASCADE (Cluster-based Accurate Syntactic Compression of Aggregated Data in VANETs) data aggregation technique. CASCADE organizes known vehicles into clusters, the size of which determines both the frame size used to distribute aggregated data and the distance ahead that vehicles are aware of (local view). We determine the optimal cluster size to balance the trade-off between local view length and expected frame size. The original CASCADE description does not consider security issues, so we present our framework for a secure CASCADE by employing received signal strength and laser rangefinders for position verification.

Accurate data aggregation for VANETs
VANET '07: Proceedings of the fourth ACM international workshop on Vehicular ad hoc networksData aggregation is an important issue for vehicular ad-hoc networks (VANETs). Congestion notification applications are built to warn drivers of traffic slowdowns far enough in advance that the drivers may take alternate routes. Data that is broadcast ...
Data aggregation in VANETs: the VESPA approach
Mobiquitous '08: Proceedings of the 5th Annual International Conference on Mobile and Ubiquitous Systems: Computing, Networking, and ServicesVESPA (Vehicular Event Sharing with a mobile P2P Architecture) is a system designed for vehicles to share information in vehicular ad-hoc networks (VANETs). The originality of VESPA is to support any type of event (e.g., available parking spaces, ...
