This paper proposes a reversible data hiding scheme for vector quantization (VQ)–compressed images based on search order coding (SOC). Data is embedded by choosing one of the possible ways to represent each embeddable index and outputted code is legitimate SOC code. The proposed scheme has two advantages. First it is more secure, comparing with previous SOC based schemes that generate non–legitimate codes as output. Second it can be used beside other schemes to embed more data and also it is a solution for the problem of transmission of side information of schemes which their outputs are legitimate VQ codes.<\div>

The rapid growth in demand for computational power has led to a shift to the cloud computing model established by large–scale virtualized data centers. Such data centers consume enormous amounts of electrical energy. Cloud providers must ensure that their service delivery is flexible in order to meet various consumer requirements. However, in order to support green computing, cloud providers also need to minimize the cloud infrastructure energy consumption while conducting the service delivery. In this study, for cloud environments an energy–aware VMs consolidation is proposed. These algorithms have been implemented and evaluated using CloudSim simulator. Related simulation results shows improvement in QOS metrics. Simulation results demonstrate that there is a trade–off between energy consumption and quality of service in the cloud environment<\div>
