Cars as Roadside Units: A Cooperative Solution

Abstract

Abstract-The gradual penetration of Dedicated Short Range Communications Radio (DSRC) technology in the years to come is a formidable problem that could adversely effect the implementation of safety and non-safety applications. In this paper, we propose a solution that might mitigate the negative impact of the partial and gradual penetration problem of DSRC technology. The proposed solution is based on a self-organizing network paradigm that draws its inspiration from biological systems, such as social insect colonies [1]. By designing the local rules and a distributed algorithm needed to perform this function, it is shown that DSRC-equipped cars can indeed serve as RSUs. Results show that the message reachability and connectivity in urban vehicular networks can be increased substantially in a cost-effective manner as the proposed approach does not entail deployment of infrastructure-based RSUs.

A Multiband Proximity-Coupled-Fed Flexible Microstrip Antenna for Wireless Systems

“…The designed antenna, due to its bandwidth characteristics, can be suitable for applications related to the Vehicle-to-Vehicle (V2V) Communication Systems, employed to provide safety warnings and traffic information, such as the Wireless Access in Vehicular Environments (WAVE)/Dedicated Short Range Communication (DSRC) based Intelligent Transportation System (ITS) [25,26] and also for short range communications devices employed in V2V and in vehicleto-roadside (V2R) communications units [27]. As a matter of fact, the operating bandwidth required for these systems is very limited (from 20 to 80 MHz around the operating frequency of 5.8 GHz) [25,26].…”

Cars as roadside units: a self-organizing network solution

“…Vehicles that act as temporary RSUs can make brief stops during which they act as a communication bridge for other vehicles in the network [2], [3]. We envision that using vehicles as RSUs could improve not only the message reachability and network connectivity but also accelerate the adoption of DSRC technology in addition to avoiding the cost of deploying Roadside Units.…”
