The BTnode platform is a versatile and flexible platform for functional prototyping of ad hoc and sensor networks. Based on an Atmel microcontroller, a Bluetooth radio and a low-...
The lifetime of wireless sensor networks can be increased by minimizing the number of active nodes that provide complete coverage, while switching off the rest. In this paper, we ...
Localization is an important and extensively studied problem in ad-hoc wireless sensor networks. Given the connectivity graph of the sensor nodes, along with additional local info...
