A Scalable Collect
نویسندگان
چکیده
In a multicasting application it is often desirable for a source to get information on the status of receivers. We call this operation a collect. In large scale groups it is not feasible to have individual messages flowing from each receivers to the source. We present a collect using a hierarchical control structure which progressively aggregates data from subsets of receivers to the source. The hierarchical control structure is based on a control structure that is also used for implementing reliable multicast. In this paper we propose such a collect mechanism, called CAGE. We describe several types of collects (standard, scheduled, asynchronous) depending mainly on when aggregation of data starts. We then show how the collect propagates intermediate results into the control structure.

متن کاملIntelligent scalable image watermarking robust against progressive DWT-based compression using genetic algorithms
Image watermarking refers to the process of embedding an authentication message, called watermark, into the host image to uniquely identify the ownership. In this paper a novel, intelligent, scalable, robust wavelet-based watermarking approach is proposed. The proposed approach employs a genetic algorithm to find nearly optimal positions to insert watermark. The embedding positions coded as chr...
