Design and evaluation of TLV-eCAST for safety message dissemination in VANETs

Abstract

Vehicular ad hoc networks (VANETs) will play a vital role in reducing the number of road accidents and fatalities as well as vehicular traffic optimization. In this paper, we propose TLV-eCAST, the last vehicle based early broadcasting for disseminating safety-related alert message in VANET. The proposed TLV-eCAST uses the early warning system on the basis of time to collision (TTC) as well as just broadcasting by the last vehicle in the transmission range of sending vehicle. The performance of TLV-eCAST is evaluated through simulation and compared with other message dissemination algorithms. © 2014 Springer-Verlag Berlin Heidelberg.
