摘要：With fast-growing consumer demands and rapidly-developing mobile technologies, portable mobile devicesare becoming a necessity of our daily lives. However, existing mobile devices rely on the wireless infrastructure toaccess Internet services provided by central application providers. This architecture is inefficient in many situations andalso does not utilize abundant interdevice communication opportunities in many scenarios. This paper proposes thehuman network (HUNET), a network architecture that enables information sharing between mobile devices throughdirect interdevice communication. We design B-SUB, an interest-driven information sharing system for HUNETs. InB-SUB, content and user interests are described by tags, which are human-readable strings that are designated by users.An experiment is performed to demonstrate the effectiveness of this tag-based content description method. To facilitateefficient data dissemination, we invent the Temporal Counting Bloom filter(TCBF) to encode tags, which also reduces the overhead of content routing. Comprehensive theoretical analyses on theparameter tuning of B-SUB are presented and verify B-SUB’s ability to work efficiently under various networkconditions. We then extend B-SUB’s routing scheme to provide a stronger privacy guarantee. Extensive realworldtrace-driven simulations are performed toevaluate the performance of B-SUB, and the results demonstrate its efficiency and usefulness
