Twiddlenet: Metadata Tagging and Data Dissemination in Mobile Device Networks.

摘要

Current mobile devices are much more than the limited modality communication tools or digital assistants they were only a few years ago; instead they offer a range of content capture capabilities, including high resolution photos, videos and sound recordings. Their communication modalities and processing power have also evolved significantly. Modern mobile devices are very capable platforms, many surpassing their desktop cousins only a few years removed. TwiddleNet is a distributed architecture of personal servers that harnesses the power of these mobile devices, enabling real time information dissemination and file sharing of multiple data types from commercial-off-the-shelf platforms. This thesis focuses on two specific issues of the TwiddleNet design; metadata tagging and data dissemination. Through a combination of automatically generated and user input metadata tag values, TwiddleNet users can locate files across participating devices. Metaphor appropriate custom tags can be added as needed to insure efficient, rich and successful file searches. Intelligent data dissemination algorithms provide context sensitive governance to the file transfer scheme. Smart dissemination reconciles device and operational states with the amount of requested data and content to send, enabling providers to meet their most pressing needs, whether that is continuing to generate content or servicing requests.
