On the Fixpoint Problem of QoE-based Charging (Invited Paper)
نویسندگان
چکیده
While with traditional QoS-based charging the pricing structure mainly reflects the delivered QoS in order to regulate the demand, the role of service prices in a Quality of Experience (QoE) context is more complex. Amongst others, the charged price may in addition have a direct impact on the user's quality perception. In this paper, we analyze the structure of the resulting fixpoint problem and discuss the corresponding equilibrium. Based on recent user trials, additional insight into the characteristics of the related feedback loops is provided, before we conclude with outlining some consequences for future QoE-based charging mechanisms.

QoE-aware Power Management in Vehicle-to-Grid Networks: a Matching-theoretic Approach
Frequency, time and places of charging and discharging have critical impact on the Quality of Experience (QoE) of using Electric Vehicles (EVs). EV charging and discharging scheduling schemes should consider both the QoE of using EV and the load capacity of the power grid. In this paper, we design a traveling plan-aware scheduling scheme for EV charging in driving pattern and a cooperative EV c...

DC fast charging (DCFC) and optimal placing of them is a fundamental factor for the popularization of electric vehicles (EVs). This paper proposes an approach to optimize place and size of charging stations based on genetic algorithm (GA). Target of this method is minimizing cost of conversion of gas stations to charging stations. Another considered issue is minimizing EVs losses to find neares...
متن کاملCharging for Quality-of-Experience: A New Paradigm for Pricing IP-based Service
Over the last couple of years, the interdisciplinary research area of “Internet Economics” has received rapidly increasing attention, especially regarding various proposals for Qualityof-Service (QoS) aware charging of IP services. However, the continuously strong trend towards flat-rate pricing in today’s fixed and mobile networks indicates that QoS differentiation does not provide a suitable ...
متن کاملA Novel Charging Plan for PEVs Aggregator Based on Combined Market and Network Driven Approach
With the large-scale production of plug-in electric vehicles (PEVs), a new entity, the PEV fleet aggregator manages charging and discharging processes of the vehicles. The main objective of an individual aggregator in interaction with electricity markets is maximizing its profit. In this paper, the performance of this aggregator in day-ahead and real-time electricity markets, considering (a) cu...
