The Design of a Low Power MEMS Based Micro-hotplate Device Using a Novel Nickel Alloy for Gas Sensing Applications

In this paper comparative analysis of MEMS (Micro-electro-mechanical System) based Micro-hotplate using three different heating elements use as separately are presented. Three different materials (viz. DilverP1, Polysilicon, and Platinum) are used as heating elements with same thickness of 0.2 µm. CoventorWareTM simulator has been used for construction of 3D model and electro-thermo-mechanical analysis of Micro-hotplate device. Power consumption, stress and displacement of Micro-hotplate are studied at operating temperature (165 ºC). It is obtained that power consumption, stress and displacement of Dilverp1 heating element are 13.06 mW, 190 MPa and 0.028 µm which are less in comparison to those with Poly Silicon heater and Platinum heater at moderate temperature (150-200 °C) over the sensing material (ZnO).

Cellular Automata Based Data Security Scheme in Computer Network using Single Electron Device

The internet conceptualized new ways of social interaction, activities globally. Internet serves billions of users worldwide. By the end of 2011it is expected that 22% of the world’s population will regularly surf internet. Beside this, internet incorporated high risks for e-users by enabling intruders to gain access via security holes. Network security is a course of action for assuring data from illicit accessing, exploitation, exposure, damage, alteration, or disorders related to the impulsive growth of popularity of e-users. Cellular Automata (CA) has been recommended in favor of the potential usage of data security. Single Electron devices (SED) have unanimously contributed in significant reduction of size of electronic devices and are now weighed up as the best substitute of future device family. Here we address a novel adaptive method to assimilate CA using SED in data security

Design and Analysis of a High Speed, Power Efficient 8 Bit ALU Based on SOI / SON MOSFET Technology

This paper shows an overall performance comparative analysis in terms of Average Power Consumption, Average Delay and Power-Delay Product for an 8 bit Arithmetic Logic Unit (ALU) using bulk MOS, Silicon-on-Insulator (SOI) and Silicon-on-Nothing (SON) technology. The entire design is done in 32nm technology for all the three cases (Bulk, SOI & SON) and then compared. The comparisons have been carried out with the help of the simulation runs on Synopsys HSpice tool, and that clearly indicates, for lower Supply Voltages (Vdd), SOI / SON technology provides a significant reduction in Average Power Consumption, Average Delay and Power-Delay Product compared to that of Bulk MOS technology.

A Novel Power Efficient Routing Scheme for Wireless Sensor Networks

The nodes in a sensor network are severely constrained by energy. Reducing the energy consumption of the nodes to prolong the network lifetime is considered a critical challenge while designing a new routing protocol. In this paper we propose a new power-aware, adaptive, hierarchical and chain based protocol - CCPAR (Clustered Chain based Power Aware Routing) that utilizes the periodic assignments of the cluster head role to different nodes based on the highest residual battery capacity for ensuring the even dissipation of power by all the nodes. Transmission from a single cluster head to the base station in each round and the distribution of the data aggregation workload among all the nodes, save the cluster heads from early exhaustion. The use of data aggregation also reduces the amount of information to be transmitted to the base station. By chaining the nodes in each cluster and using a separate chain for the cluster heads, CCPAR offers the advantage of small transmit distances for most of the nodes and thus helps them to be operational for a longer period of time by conserving their limited energy. The simultaneous construction of multiple chains in different clusters reduces the time for chain construction as well as the length of each of the chains. These shorter length chains solve the problem of excessive delay in transmission for the distant nodes. Use of a fresh set of parameter values in each round provides the users the flexibility to change these values in a way to control the power consumption. The introduction of MAX threshold enables CCPAR to be quickly responsive and thus highly suitable for time critical applications. From the performance evaluation we observe that CCPAR outperforms other protocols in terms of energy saving and longevity of the network
