Modeling Energy & Reliability of a CNT based WSN on an HPC Setup
Abstract
We have analyzed the effect of innovations in Nanotechnology on Wireless Sensor Networks (WSN) and have modeled Carbon Nanotube (CNT) based sensor nodes from a device prospective. A WSN model has been programmed in Simulink-MATLAB and a library has been developed. Integration of CNT in WSN for various modules such as sensors, microprocessors, batteries etc has been shown. Also average energy consumption for the system has been formulated and its reliability has been shown holistically. A proposition has been put forward on the changes needed in existing sensor node structure to improve its efficiency and to facilitate as well as enhance the assimilation of CNT based devices in a WSN. Finally we have commented on the challenges that exist in this technology and described the important factors that need to be considered for calculating reliability. This research will help in practical implementation of CNT based devices and analysis of their key effects on the WSN environment. The work has been executed on Simulink and Distributive Computing toolbox of MATLAB. The proposal has been compared to the recent developments and past experimental results reported in this field. This attempt to derieve the energy consumption and reliability implications will help in development of real devices using CNT which is a major hurdle in bringing the success from lab to commercial market. Recent research in CNT has been used to model an energy efficient model which will also lead to the development CAD tools. Library for Reliability and Energy consumption includes analysis of various parts of a WSN system which is being constructed from CNT. Nano routing in a CNT system is also implemented with its dependencies. Finally the computations were executed on a HPC setup and the model showed remarkable speedup.
