Abstract
With the rapid growth of interest in media-rich user experience, content distribution networks (CDNs) gained considerable attention. Since, most of the energy is consumed by cache points (CPs) and the associated equipment, it is imperative to deploy fewer number of CPs or switch off as many as possible to save energy. This results in degraded quality of service (QoS). It is an usual dimensioning technique to optimise the number and locations of caching points (CPs) of a content distribution network (CDN), where the objective is to reduce operational energy. In this paper, we reduce non-renewable energy consumption (carbon footprint) by introducing renewable grid energy (in the form of wind energy) and adaptive CPs. Further, we propose algorithms for provisioning high number of simultaneous downloads, which reduce overall waiting time and number of dropped request of city vehicular users. The end result is substantial improvement in quality of service (QoS). The proposed CPs save 100% grid energy during the whole day while fulfilling content demand in a city vehicular environment.
