Incorporating ubiquitous wireless sensor networks (WSNs) and powerful cloud computing (CC), Sensor-Cloud (SC) is attracting growing attention from both academia and industry. However, pricing for SC is barely explored. In this paper, filling this gap, five SC pricing models (i.e., SCPM1, SCPM2, SCPM3, SCPM4 and SCPM5) are proposed first. Particularly, they charge a SC user, based on 1) the lease period...
The uncertainty of cloud resources makes task scheduling very difficult, and may results in a waste of energy of cloud resources if some cloud resources stay in unusable state for a long time. This paper proposes the cloud resource evaluation model based on entropy optimization (EOEM) to solve the uncertain problem. The evaluation results also can be used to develop resource management strategies,...
