Cloud computing will be a major technology in the development of the future Internet of Services. Service providers want to remove the bottle neck of the cloud computing system in order to satisfy user requirement. And in order to save energy consumption they also need to apply new energy-efficiency mechanism and observe its effects on a data center. As it is difficult to test new mechanism in real...
The high-precision positioning of obvious target for the image edge, we usually use line diffusion function model, when we generally use normal function, in this paper, we use simple arc tangent function instead of normal function for positioning the image edge, the mathematical model of this method is simple and has fast calculation. getting the gray value of the phase as observations for adjustment...
Various transmission control protocol (TCP) improvement schemes have been proposed to improve TCP performance over complex wireless networks. Some of them consider reducing the ACK packets, such as TCP-DBA. However, this scheme doesn't perform so well in wireless network with high packet delay and multi-hop. In this paper, a new enhanced scheme has been proposed to improve TCP performance in such...
