We have analyzed the effect of innovations in Nanotechnology on Wireless Sensor Networks (WSN) and have modeled Carbon Nanotube (CNT) based system. We have shown the integration of CNT in WSN and formulated a Nano routing system. A proposition is put forward by us on the changes needed in the existing sensor node structure to improve its efficiency and to facilitate and enhance the assimilation of CNT based devices in a WSN. We have shown the functioning of CNT based Nano devices in WSN technology. Finally we have commented on the challenges that exist in this technology and described the important factors that need to be kept under consideration for the calculation of the energy of CNT based WSN.
