PROJECT TITLE :

A Stochastic Geometry Model for Multi-Hop Highway Vehicular Communication - 2016

ABSTRACT:

Carrier sense multiple access (CSMA) protocol is standardized for vehicular Communication to make sure a distributed and economical communication between vehicles. However, several vehicular applications require efficient multi-hop info dissemination. This paper exploits stochastic geometry to develop a tractable and accurate modeling framework to characterize the multi-hop transmissions for vehicular networks in an exceedingly multilane highway setup. In explicit, we study the tradeoffs between per-hop packet forward progress, per-hop transmission success probability, and spatial frequency reuse (SFR) efficiency imposed by different packet forwarding schemes, namely, most forward with fastened radius (MFR), the nearest with forward progress (NFP), and therefore the random with forward progress (RFP). We additionally outline a brand new performance metric, denoted as the mixture packet progress (APP), that is a dimensionless quantity that captures the aforementioned tradeoffs. To this finish, the developed model reveals the interplay between the spectrum sensing threshold (?th) of the CSMA protocol and also the packet forwarding theme. Our results show that, contrary to ALOHA networks, that continuously favor NFP, MFR might achieve the highest APP in CSMA networks if ?th is correctly chosen.
