摘要：

ln sensor networks, it is crucial to design and employ energy-efficient communication protocols since nodes are battery-powered, and thus their lifetimes are limited. We propose a data dissemination protocol for periodic data updates in wireless sensor networks, called SAFE (sinks accessing data from environments), which attempts to save energy through data delivery path sharing among multiple sinks that have common interests. Simulation results show that the proposed protocol is energy-efficient as well as scalable to a large sink population.
