With the advent of cloud computing, organizations tend to buy services from data centers of major cloud vendors. In contrast, community cloud computing as described in [1] gives an alternative way to reduce the costs or even obtain free resources, by sharing among communities. Because the utilization of computing resources in an organization is not constantly 100%, other members of the community can exploit these excessive resources. In this paper, we design algorithms for admission control and resource allocation, in order to deal with unreliably excessive computing resources. Furthermore, we introduce a social price in order to manage the allocation more efficiently, both in terms of social relations and of revenue.

Internet of Things (IoT) services have grown substantially in recent years. Consequently, IoT service providers (SPs) are emerging in the market and competing to offer their services. Many IoT applications utilize these services in an integrated manner with different Quality-of-Service (QoS) requirements. Thus, the provisioning of end-to-end QoS is getting more indispensable for IoT platforms. However, provisioning the system by using only QoS metrics without considering user experiences is not sufficient. Recently, Quality of Experience (QoE) model has become a promising approach to quantify actual user experiences of services. A holistic design approach that considers constraints of various QoS/QoE metrics together is needed to satisfy requirements of these applications and services. Besides, IoT services may operate in environments with limited resources. Therefore, effective management of services and system resources is essential for QoS/QoE support. This paper provides a comprehensive survey for the state-of-the-art studies on IoT services with QoS/QoE perspective. Our contributions are threefold: (1) QoEdriven architecture is demonstrated by classifying vital components according to QoE-related functions in prior studies, (2) QoE metrics and QoE optimization objectives are classified by corresponding system and resource control problems in the architecture, and (3) QoE-aware resource management e.g., QoE-aware offloading, placement and data caching policies with recent Machine Learning approaches are extensively reviewed.
