Energy and QoS Evaluation for a V2R Network

In this paper, the authors study the Quality of Service (QoS) and energy performance of the Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) based 802.11p scheme, and their previously proposed Modified version of Packet Reservation Multiple Access (M-PRMA) scheme for a Vehicle-To-Roadside (V2R) network in a motorway environment. The simulation results illustrate the deficiency of the 802.11p protocol in providing adequate QoS to support real-time communication for varying vehicular traffic loads expected on the motorway. The significant amount of energy required for carrier sensing in the 802.11p is realized when compared to the low listening energy expenditure levels of the M-PRMA protocol.
