“Enabling Electromagnetic Communication in
Wireless Nanosensor Networks”
Josep Miquel Jornet, Georgia Tech
Nanotechnology is enabling the development of miniaturized sensors that can detect with unprecedented accuracy nanoscale events such as the presence of chemical compounds in concentrations as low as one part per billion or the existence of different biological agents such as virus, bacteria or cancerous cells. Wireless nanosensor networks (WNSNs) will expand the capabilities of single nanosensors by allowing them to cooperate and share information. Classical communication paradigms need to undergo a profound revision before being used in the nanoscale. I will survey the state of the art in nanosensor technology from the device perspective, giving details on the internal architecture and components of an individual nanosensor device as well as the main challenges in their integration in a single unit. After reviewing the different options for communication among nanosensors, the use of electromagnetic waves in the terahertz frequency range is justified from the device perspective and in light of the quantum properties affecting nano-antennas. Then the characteristics of the terahertz channel in the nanoscale are reviewed, emphasizing the need of new solutions for communication in WNSNs. Finally, the open research challenges in terms of network architectures, algorithms and protocols for nanosensor networks are highlighted, defining a roadmap for the development of this new networking paradigm.
Josep Miquel Jornet is pursuing his PhD in the Broadband Wireless Networking Laboratory at Georgia Tech under the supervision of Dr. Ian F. Akyildiz. His research interests concern nanonetworks in general and electromagnetic nanosensor networks in particular. He holds an MS in information and communication technologies from the Universitat Politècnica de Catalunya in Barcelona and was previously a visiting researcher at the MIT.
