Scalable Techniques for Large Scale Dynamic Channel Building

摘要

This report summarizes the research and software artifacts produced as part of the Agile Information Control Environment (AICE) program in the area of real-time content-based information dissemination through resource- constrained channelization. By identifying opportunities to multi cast shared information needs to multiple users simultaneously, channelization increases the information throughput of information dissemination system while balancing the sender/receiver processing load. Multiple channelization algorithms are presented within this report and their characteristics explored. A mathematical framework for analyzing these algorithms is outlined and corresponding measures of effectiveness defined. Besides theoretical analysis, the report outlines simulation-based models and operational tools used to quantify the various algorithms' performance within the context of the theoretical measurements. From our analysis and simulations based on operational missions, the report concludes that channelization can reduce the network load while increasing the information throughput by more than 100% compared to traditional unicast stove-pipe approaches.
