Intricate Modeling and Analysis of CNT and MEMS based Sensor Nodes
Post: #1



We have analyzed the effect of innovations in Nanotechnology on Wireless Sensor Networks (WSN) and have modeled Carbon Nanotube (CNT) and Micro-Electro- Mechanical Systems (MEMS) based sensor nodes. SUGAR library in MATLAB has been used to illustrate the static analysis of deflection, display the structure and to compute the displacement parameters of a cantilever beam subjected to an external force. A WSN (Wireless Sensor Network) model has been programmed using Simulink in MATLAB. We have shown the integration of CNT in WSN as CNT based sensors, microprocessors, batteries etc. 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 reliability of CNT based devices and their key effects on the WSN environment.


The combination of recent technological advances in electronics, nanotechnology, wireless communications, computing, and networking has hastened the development of Wireless Sensor Networks (WSNs) technology. Wireless Sensor and Actor Networks (WSANs) constitute an emerging and pervasive technology that is attracting increased interest for a wide range of applications. WSN see application in various areas like space research, biomedical engineering, military applications such as battlefield surveillance and the quest for making low power, reliable and cheap sensor nodes has been a prime focus in recent years. We know that Nanotechnology has enabled realization of low power devices such as MEMS devices and CNT based FETs [11-12]. CNT based sensors have shown many benefits over their past counterparts and are suitable candidates in this Nanotechnology driven age [24]. Nanotechnology uses the smallest unit of matter to engineer new materials and devices atom by atom, aiming at achieving superior properties and performance through atomic scale architecture. An improvement in techniques of Nano-characterization and Nano-fabrication has helped us to pave the way to develop many novel materials that can be applied to various spheres of technology. For example the impact of Nanotechnology on Wireless Communications has been shown by Er. Ping Li in [14]. An Architecture of Quantum-Based Nano-sensor Node for Future Wireless Sensor Networks has been proposed [10]. WSN in space application has been shown in [6] which use adaptive MEMS antennas. Wireless Sensor Networks with Biomedical Applications has been shown by Zachary Walker describing the importance of Middleware [22]. Miniature Acoustic Communication Subsystem Architecture for Underwater Wireless Sensor Networks has been proposed by Saunvit Pandya [33]. WSN architecture for the Wireless Health Mobile Bio-diagnostic System for physiological studies has been proposed [34]. Thus, we have expanded and proposed designing and modeling of MEMS based array of sensors in our paper that can lead to its practical applications in these areas.
