“…Idjmayyel et al [5] reduces the energy consumption by minimizing the number of base stations while attaining the required QoS and provide an energy model for the sum of energies consumed in transmitting, receiving, listening and operating states for vehicular communication. Skordylis et al [6] proposed a development of carry-and-forward schemes that attempt to deliver data from vehicles to fix infrastructure nodes in an urban setting.…”

A solar-based vehicular ad-hoc networking technique is a key issue to exploit the on-board sensing, computing, energy harvesting, and wireless communication capabilities in the intelligent transportation system. Most existing research results mostly paid attention to the energy savings, but lacking in consideration of the energy harvesting. An electric solar vehicle considered in this paper is equipped with a solar panel so that the vehicle battery can be periodically charged while keeping the high ECR, where ECR (energy consumption ratio) is the average packet arrival ratio divided by the energy consumption. This paper proposes a new green time-bounded routing protocol, whose goal is to deliver messages to the destination within user-defined delay and to minimize the usage of radio and power consumption, because the radio spectrum and the power are the limited resources. Simulation results justify the efficiency of the proposed protocol.

Vehicular ad-hoc network (VANET)-based multimedia applications are considered to play a very important role in the future of intelligent transportation systems and vehicular infotainment systems. Socio-economic issues are identified among the main challenges in VANET-based multimedia applications. In response to these challenges, this paper proposes a novel user-oriented cluster-based multimedia delivery solution over VANETs that is able to address vehicle passenger preferences and deliver multimedia content of their interest. Such a solution will support various value added services in the vehicles, e.g. touristic video guide, news, entertainment, etc. In this paper the architecture of the proposed solution is presented together with the cluster-based mechanism employed for multimedia transmissions and the cluster head selection algorithm required for delivery infrastructure management. Simulation-based testing demonstrate how this solution increases system stability resulting in a longer life of the elected cluster head compared to the classic Lowest-ID cluster head algorithm, fact that positively influences the quality of the multimedia transmission.

“…To decrease the overall network energy consumption, a switching off strategy was proposed in [6], which reduced the number of base stations. A similar strategy was employed on the CPs in a city vehicular CDN, where the number and locations of the CPs were optimized with vehicle mobility and hourly traffic [7], [8].…”

-The unprecedented growth in content demand on smartphones has significantly increased the energy consumption of current cellular and backbone networks. Apart from achieving stringent carbon footprint targets, provisioning high data rates to city vehicular users while maintaining quality of service (QoS) remains a serious challenge. In previous work, to support content delivery at high data rates, the number and locations of caching points (CPs) within a content distribution network (CDN) were optimized while reducing the operational energy consumption compared to typical cellular networks. Further reduction in energy consumption may be possible through sleep cycles, which reduces transmission energy consumption. However, sleep cycles degrade the quality of service. Therefore, in this paper, we propose a novel load adaptation technique for a CP which not only enhances content download rate but also reduces transmission energy consumption through random sleep cycles. Unlike a non-load adaptive (deterministic) CP, the performance results reveal that the load adaptive CP achieves considerably lower average piece delay (approximately 60% on average during the day), leveraging the introduction of random sleep cycles to save transmission energy. The proposed CP saves up to 84% transmission energy during off-peak hours and 33% during the whole day while fulfilling content demand in a city vehicular environment.
