Novel Geocast Routing Protocols for Safety and Comfort Applications in VANets

Abstract : —Routing in cooperative vehicular networks is a challenging work due to high mobility of vehicles and difficulty of localization. In this paper, we study the geocast routing problem in Vehicular Ad-Hoc Networks (VANets), which aims at delivering data to a specific group of mobile vehicles identified by their geographical location. Although many geocast routing protocols have been proposed, only partial inherent constraints of VANets (such as mobility, frequent fragmentation and overload) are taken into account. Therefore, we propose two novel robust geocast routing protocols: The first one called Robust Geocast Routing Protocol for Safety Applications (RGRP-SA), while the other one, namely Robust Geocast Routing Protocol for Comfort Applications (RGRP-CA). Simulations conducted in NS-2 demonstrate that our safety-oriented RGRP-SA protocol outperforms the counterpart protocols in terms of number of sent packets and end-to-end delay. Besides, it is also shown that our comfort-oriented RGRP-CA protocol serves well comfort applications by providing reliable data delivery and high throughput.
