EFFECT OF TRAFFIC LIGHT SCENARIO ON VANETS CONNECTIVITY WITH LOW PENETRATION RATE

Abstract

Traffic light with Vehicular Ad-Hoc Networks (VANETs) has been developed recently. Many issues and challenges come up with this development that required an investigation. One of the most prominent challenges is connectivity under low penetration of vehicles with VANET technology. Traffic light scenario has been proposed in this field to overcome low penetration problem, but no studies have been done on their connectivity. In this paper, VANET connectivity with traffic light scenarios had been investigated. The most significant metric in this investigation is penetration rate, more specifically low values of it. Connectivity measurements, i.e. reachability, connection duration and re-healing time had been studied with real-time simulation. Three traffic light scenarios had been considered; no traffic light, normal traffic light and intelligent traffic light. The effect of these scenarios on VANET connectivity had been analyzed with low penetration rate and important conclusions had been stated for future works.
