Energy and QoS for vehicular communication in a motorway environment

This paper presents the study of an access point (AP) deployment strategy which aims to reduce the energy expenditure of ubiquitous motorway network coverage while ensuring Quality of Service (QoS) requirements are maintained at acceptable levels. For this reason, we, in this paper, study the consumption of energy in a scenario where three operational APs are deployed on a motorway with and without putting vehicular nodes into sleeping mode. To reduce the energy of ubiquitous deployment, we investigate the possibility of intermittent access point placement. This is experimented by eliminating the need for one of the three APs, however at the cost of degraded quality of service (QoS). Ad hoc setups such as multi-hop and cluster based routing (CBR) have been deployed as a replacement for a base station and QoS and energy consumption effects have been investigated. The CBR has been found to restore the performance while reducing the energy consumption significantly.
