Activities and Findings

1. Negotiation-based sharing of resources
   • Developed the Secure Content Exchange Negotiation System (SCENS), a centralized multi-interface access point where humans and agents can index, identify, and set conditions for exchange for resources
   • Formulated the MetaDL framework that underlies the SCENS system, and which provides for the interconnection of existing data repositories through exchanges of metadata
   • Created complementary approaches based on metadata analysis for indexing and retrieval of images and other multimedia objects
   • Developed an automated trust negotiation (ATN) model based on extending current approaches to include third parties

2. Routing, analysis, and optimization in peer-to-peer and sensor networks
   • Developed new routing approaches for peer-to-peer and sensor networks

3. Cyber-security tool development
   • Created a social network-based tool for analyzing and visualizing activity in peer-to-peer, negotiation, and dynamic situations
   • Developed new collaborative filtering tools based on formation of recommendations from the data in distributed clients

4. Biweekly educational seminars on topics related to resource sharing, networks, and security
