High-Gain Stacked Minkowski Fractal Patch Antenna with Superstrate for 60GHz Communications,is added above the ground plane in order to increase the gain.The maximum simulated gain of the antenna with superstrate reaches 14.1dBi at 60GHz and is more than 10dBi all over the 60GHz band(from 57GHz to 64GHz). It is noted that by stacking the antenna and using H-shaped aperture coupling the ban

Tree-Mesh Based P2P Streaming Data Distribution Scheme, and the mesh-based structures have respective flaws while distributing the media data. The tree-based structure is highly vulnerable, so it is very suitable for the stable environment in small scale. And the mesh-based structure is quite stable, and can guarantee certain grade of service under the

A Dual-Decomposition-Based Resource Allocation for the Data Transmission in the Internet,ate allocation that the utility functions can be nonconcave and nondifferetiable, which turns utility maximization into nonconvex, constrained optimization problem that is well-known to be difficult. To solve this problem, the paper derives an important property for the dual decomposition of the ori
