We consider data-streaming from an access point to multiple receivers, which is modeled as packet erasure channel. A simple network coding is shown to achieve larger rate region than without network coding, using minimal control information. The performance is characterized exactly using state transition graph. The scheme is then mapped to an information theoretic formulation for broadcast channel...
Image segmentation is the key step from image processing to image analysis. Ostu thresholding, which features a good performance, is one of the main image threshold segmentation methods. Like other threshold methods, the application of the Otsu has been restricted for the long-paying computation. In order to overcome the disadvantages and get better results, a new method based on quantum particle...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
