This final report summarizes technical achievements made for Phase I STTR project, entitled Autonomous Distributed System - Multiple-Level Distributed Data Fusion for Future DADS Using Bayesian Network Technology -, during the period from 1 July 2001 to 15 January 2002. The future DADS, also known as mini-DADS or micro-DADS, is the next-generation DADS envisioned for 2020 littoral undersea threats. The most prominent feature of the future DADS is the elimination of a fiber line for an acoustic arrays for each of the current DADS sensor node, which poses a wide variety of technical challenges to implement distributed data fusion, including target detection, tracking, and classification. The Phase I efforts are to show technical feasibility of application of the distributed Bayesian network inference algorithms developed by IET and OSU in the past decade. Communication between nodes is conducted using Bayesian networks fragments to represent local information, and Bandwidth Agile Situation Dissemination technique for transmitting Bayesian network fragments in face of communication limitations.
