Long-range and energy-efficient optical networking for tiny sensors

Acquiring real time sensory data using remote swarms of tiny sensors depends on efficient wireless networking. Often, battery longevity of the sensors is a critical design requirement, which makes long-range RF transmission inadequate for this task. A common solution is to use short-range and energy-efficient RF protocols within the swarm, then communicate with the outside world via a capable agent or a networking gateway. In this paper we...
