Prime Grant Support: NSF • Currently, while on the move, people cannot efficiently search for local resources, particularly if the resources have a short life, e.g. an available parking slot, or an available workstation in a large convention hall. • Applications in matchmaking and resource discovery in many domains, including • social networks • transportation and emergency response • mobile electronic commerce. • Use Database and Publish/Subscribe technology to specify profiles of interest and resource information • Peer-to-Peer information exchange among mobile devices such as cell phones and pda’s, that form ad hoc network • Exchange uses short-range, unlicensed wireless communication spectrum including 802.11 and Bluetooth. • Exchanged information is prioritized according to a spatial-temporal relevance function to reduce bandwidth consumption and cope with unreliable wireless connections. • Adaptive push/pull of resource information • Developed and analyzed search algorithms for different mobility environments and communication technologies. • Designed a comprehensive simulation system that enables selection of a search algorithm. • Built a prototype system • Published 6 papers, received $250k in NSF support, delivered two keynote addresses on the subject. • Submitted provisional patent application • Future goals: design complete local search system, combine with cellular communication to central server, test technology in real environment, transfer to industry.
