This paper looks at the problem of delivering QoS controlled video streams from a single point (known as the headend or the distribution server) to to a collective of recipient nodes over a shared Internet backbone. Due to fact that the available bandwidth on the Internet backbone is highly variable and the bandwidth demands of the individual streams are(More)
The WiMAX OFDMA environment is unique in that it requires a two-dimensional allocation i.e. simultaneously in time and frequency on the downlink. The downlink resource has to be broken into sub-rectangles, each of which is allocated to one or more flows. In this paper, we have proposed a fast allocation algorithm to allocate the downlink resource to(More)
Image inversion techniques revolving around Tikhonov regularization try to use local heuristics to clean the noise and recover the image. We propose a segmentation based inversion algorithm which can recover the structural information in a two-dimensional image data composed of continuous sub-regions with discontinuous and disjoint adjacencies. We present(More)
We describe the design and implementation of a network layer interfacing scheme, which permits an 0%8072 transport layer process to operate on a variety of network layer implementations. We describe a mapping function that would create a correspondence between the network services required by the correspondent transport process and the set of network(More)

MIMO broadcast networks are an emerging technique for maximizing resource sharing in dense cellular networks; by using techniques based on dirty-paper coding, it is possible for a single transmitter to simultaneously service multiple receivers, by pre-subtracting interference. A different but related problem is InterCell Interference Coordination, where two(More)
