Similarly Ubiquitous computing is the rising trend of implanting computational ability into everyday objects to make them efficiently communicate to accomplish useful tasks. The evolution of these technologies leads to exponential growth of smart sensors and devices which require faster, secure, energy efficient data transmission. Light fidelity otherwise called as Li Fi is the high speed wireless communication technology that applies light as medium through light emitting diodes and is a greener, secure and safer technology for ubiquitous communication in IoT. In this paper firstly, we will understand the working of Li Fi. Secondly, we will see the role of Li-Fi in IoT and finally discuss how Li + Wi Fi is a true enabler of IoT.

The design is implemented in 130nm CMOS technology. In comparison to other conventional technique the proposed LNA shows improvement in performance parameter such as NF, gain, stability and power dissipation. . In this paper a CMOS inverter along with resistive negative feedback is used to provide necessary biasing and impedance matching at input port. The LNA design is inductorless and hence the size is small. Using this technique LNA shows a gain of 34-22 dB with a noise figure of 1.6-1.9dB for operating bandwidth of 600 MHz – 3GHz. The proposed LNA drains 13mA current from 1.2V power supply.

Here, CMOS inverter based wideband LNA is used in this design. Input Impedance matching is achieved by using negative resistive feedback along with feed-forward topology. The proposed amplifier achieves wideband input matching with S11 of less than -10 dB for overall bandwidth range. The designed LNA demonstrates a 33--24dB voltage gain (S21), 1.6—1.9dB noise figure (NF) with IIP3 of +8.02dB. The design drains 13mA of current from 1.2v supply with power consumption of 15.6mW.

Machines have become autonomous and, for the efficient operation of systems, decision-makers require a clear picture of the plant's situation and overall performance. Sensors provide real-time machine data that can assist in understanding trends, enabling experts to analyze and optimize processes and also provides the ability to predict faults. Thus, providing access to plant data at the right level and time is critical for effective operations. Operators are required to quickly spot issues in real-time to take corrective measures which require effective delivery of information using specific Data Visualization techniques. This paper depicts a system developed by the integration of the latest technologies to virtually visualize the performance of an industrial plant for decision-guiding insights to reduce problems and improve production.

Gas Filling Plants are used to fill, count & deliver Gas Cylinder ensuring an automated & efficient batch production. Increase in overall efficiency and safety of the Gas Filling Station by introducing Supervisory and Data Acquisition System which overcomes human intervention although the different types of devices are used. This system is designed using a master and slave modules consisting of ARM microcontroller, GSM module and ZigBee module. In this system, slave module monitors various parameter of Gas Plant and sends the data to remote based master module. Depending on the data received by slave, master controls various devices of slave module. Here, both slave and master controller is LPC2148. For data transmission through GSM, a tri band GSM/GPRS engine STM300 is used due to its ability to support TCP/IP protocol. The sensor node is implemented using ARM 7 microcontroller pro...
