An Overview of Directed Diffusion

TL;DRAbstract

this paper examines a new data dissemination paradigm for such sensor networks. This paradigm, which we call directed diffusion , is data-centric. Data generated by sensor nodes is named by attribute-value pairs. A node requests data by sending interests for named data. Data matching the interest is then "drawn" down towards that node. Intermediate nodes can cache, or transform data, and may direct interests based on previously cached data (Section 3)
