Performance Comparison of IEEE 802.11p and IEEE 802.11b for Vehicle-to-Vehicle Communications in Highway, Rural, and Urban Areas

Abstract

Communication between vehicles has recently been a popular research topic. Generally, the Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), and Infrastructure-to-Infrastructure (I2I) communications applications can be divided into two sections: (i) safety applications and (ii) nonsafety applications. In this study, we have investigated the performance of IEEE 802.11p and IEEE 802.11b based on real-world measurements and radio propagation models of V2V networks in different environments, including highway, rural, and urban areas. Furthermore, we have investigated the most used V2V mobility models and simulation tools. Comparative performance evaluations show that the IEEE 802.11p achieves higher network throughput, low end-to-end delay, and higher delivery ratio compared to IEEE 802.11b. Overall, our main objective is to describe potential advantages, research challenges, and applications of V2V networks and show how IEEE 802.11p and IEEE 802.11b will perform under different radio propagation environments.

Radio Communication for Communications-Based Train Control (CBTC): A Tutorial and Survey

“…Typical IEEE 802.11p applications include safety-related traffic updates, route guidance, parking assistance etc. [170].…”

“…The band is divided into 1 control channel and 6 service channels. Similarly, in Europe, it has been allocated a 20 MHz spectrum [170]. The limited number of control channels reduces the time required to search for an AP, thereby making the process of connection establishment faster [83].…”

“…It is more restrictive in terms of the usage and the radio technologies, and thus automatically reduces most of the interference problems inherent in the ISM band [171]. Table VIII summarizes the data rates as well as communication ranges supported [170]. IEEE 802.11p allows all nodes to be on the same channel and configured with the same SSID by default.…”

Performance Evaluation of 802.11p-Based Ad Hoc Vehicle-to-Vehicle Communications for Usual Applications Under Realistic Urban Mobility

“…On one hand, efficient resource management and service access could be achieved through vehicular cloud networks, and on the other hand, the passengers inside the vehicles could benefit of innovative applications while the vehicle will be in an almost autonomous [6]. The one presented in [2] is one of the most complete.…”

“…The results presented in Fig. 14 represent respectively the wireless LAN state when only one application is running (first row: the results are the average over scenarios 1,3,4,5,6,7,8), when three applications are running (second row: the results come from scenario 9) and when a full mesh traffic occurs between every pairs in the network (third row: the results come from scenario 2 where 50 broadcast traffic flows were sent simultaneously). When reasonable traffic is sent (one or three applications running), AODV realizes a throughput close to the load.…”
