| Popis: | In this paper, we study the problem of quality of service (QoS)-aware cost management of sensor-cloud comprising of multiple sensor-cloud service providers (SCSPs) and sensor-owners. The rapid adaptation of the wireless sensor network (WSN) technology led to the conceptualization of the sensor-cloud infrastructure which primarily aims to reduce the complexities associated with operating WSN-based applications by rendering Sensors-as-a-Service (Se-aaS). However, the oligopolistic market scenario of sensor-cloud involving multiple SCSPs and sensor-owners significantly impacts its profitability and QoS. Thus, there is a need to explore the dynamics of this market competition elaborately in order to maintain the usability of sensor-cloud. Existing literature focusing on sensor-cloud fails to address these issues. Hence, in this work, we analyze the interactions between the SCSPs and the sensor-owners in the Se-aaS market using a game-theoretic approach. We propose a QoS-aware dynamic cost management scheme, named QUEST, to determine the optimal strategies of the various actors in sensor-cloud market. Through simulations, we observe that using QUEST, the price paid by end-users decreases by 10.31-20.43% and the profit of sensor-owners increases by 66.83-89.94%. Moreover, QUEST ensures the optimal distribution of service-requests among the SCSPs and the sensor-owners, and the satisfaction factor of the end-users. |
