Performance Analysis of Adaptive Rate Mechanism for IEEE 802.11p in DSRC for Road Safety Application in Vehicular Networks

Abstract

Dedicated Short Range Communication (DSRC) designed to be built in to every vehicle for safety and commercial non-safety application, is a robust technology that is supported by IEEE 802.11p standard due to the mobility of vehicle that cannot be avoidable. High data rate is one of the requirements for devices operating in this category. As with such, there is need for vehicles to change data rate depending on channel condition. In this paper, we have present a detailed simulation on two popular rate algorithms, Onoe and AARF in an infrastructure wireless network, and evaluation of results for different metrics is carried out.
