Intelligent routing in urban vehicular networks.

Abstract

Results demonstrate that I-TAR can achieve up to ~19% higher average packet-delivery-ratio (APDR) compared to the state-of-the-art. Additionally, the hybrid approach improves the APDR and average end-to-end delay (AEED) performances of I-TAR by 4% and about 8%, respectively. Under a more realistic scenario, where node availability is considered, a decline of up to ~51% decline in APDR performance is observed, whereas the proposed HI-TAR can increase the APDR performance by up to 50% compared to both I-TAR and the state-of-the-art. Finally, when multiple source-destination vehicle pairs are considered simultaneously, all the schemes that model and consider node availability, i.e. limited-availability, achieve from 72.2% to 82.3% lower APDR, when compared to those that do not, i.e. assuming full-availability. However, HI-TAR still provides 34.6% better APDR performance than I-TAR, and ~40% more than the state-of-the-art.
