英文摘要： The sensor network and opportunistic network technologies have presented a trend of further integration due to the trait of natural opportunistic transmission in sensor networks and the data-related features in opportunistic networks. In this project, we would compare and analyze the latest technologies of these two areas, especially focusing on combining the infrastructure-free transmission technologies in opportunistic network and content-based data distribution and caching management techniques in sensor networks to study the issues of data dissemination and gathering, data storage and cache management in opportunistic wireless sensor networks. We would propose content-based efficient and reliable data dissemination schemes using the network metadata information, and propose data gathering technologies based on pattern recognition and prediction to efficiently collect the sensing data and to optimize the mode of communications among nodes. As the data dissemination and data caching are closely linked, we would also propose context-aware data storage and cache management technologies to manage various data and to alleviate the shortage of storage space. The proposed schemes and algorithms are fundamental blocks of various applications in the opportunistic wireless sensor networks, and related research is just
