Wireless sensor network (WSN) is a group of small power-constrained nodes that sense
data and communicate it to the base station (BS). These nodes cover a vast region of …

Sensor networks are deemed suitable for large-scale deployments in the wild for a variety of
applications. In spite of the remarkable efforts the community put to build the sensor systems …

Motivated by the needs of precise forest inventory and real-time surveillance for ecosystem
management, in this paper we present GreenOrbs [2], a wireless sensor network system and …

The confluence of inexpensive wireless communication, computation, and sensing has
created a new generation of smart devices. Using tens to thousands of these devices in self …
