Abstract

Traditional sensing models assume one or a few powerful sensors and centralized computation. Today, technological trends enable the creation of inexpensive, small, intelligent devices for sensing and actuation. If many small sensors can work together as a sensor network, they provide several advantages over traditional centralized sensing. By placing the sensor close to the object being sensed, signal processing and target discrimination problems in sensing can be greatly simplified. By communicating over several short hops rather than one long hop, energy consumed in communication can be reduced [29]. Moreover, by processing data in the network, often the amount of data transferred can be reduced, further saving energy [22].
Motivated by robustness, scaling, and energy efficiency requirements, this paper examines a new data dissemination paradigm for such sensor networks. is paradigm, which we call …
