Abstract: Wireless sensor nodes typically have short memory and battery life. This limitation requires powerful algorithms that can be used to reduce power consumption. The main energy is consumed when sending data. Some of the energy is spent processing data. This document introduces another approach to reduce energy consumption. We consider both shipping and handling charges. So, it uses short range and data compression to reduce power consumption. We designed and implemented TARF, a robust trust-aware routing framework for dynamic WSNs. Without strict time synchronization or known geographic information, TARF provides reliable and energy efficient routes. Most importantly, TARF has proven effective against malicious attacks created by impersonators. TARF's robustness is verified through extensive evaluation using both simulations and demonstration experiments on large- scale WSNs under various scenarios.

Abstract: Wireless Sensor Networks (WSNs) have come predominant in both artificial operations as well as particular use. With the arrival of Internet of Things (IoT) there has been emphasis on exploration, development and operation of WSNs. WSN nodes are characterized by low processing power, limited continuance, and immobility. Our major objective is to plan and develop a WSN irrespective of these constraints with high quality. In this paper we've presented an in- depth analysis of one of these constraints i.e., limited power availability in WSNs. We've presented a review of major ways to conserve power in WSNs. Especial focus is given on AI grounded power optimization ways including clustering, fuzzy logic, neural network- based ways etc.

Abstract: Due to increasing population and COVID-19 pandemic, the biomedical wastes in the hospital are raised. The major goal of this initiative is to treat biomedical related waste properly by disposing, once the waste gets filled in the bins and to classify the biomedical waste for recycling purposes. In hospital there exists the manual detection and clearing of waste is being done once the biomedical waste bins got filled. This system of process has a high risk in contamination once the waste is not disposed at right time or when the waste is stagnant over time. Hence we proposed our project “Biomedical Waste Monitoring System And Recycling Method For Hospital Using IOT” in order to monitor the waste bins continually and alerts the concern scavenge team through automatic triggered SMS and Call facility for that 4 IR sensor, gas sensor, buzzer and GPS module are incorporated with dustbin and interfaced with microcontroller. Our system not only alerts the scavenger team when the bin gets filled, but also it will alerts the scavenger team when the bin high prone to contamination and the stinking smell exists. Using color codes of dustbin to segregate the 10 different categories of medical waste under 4 colors red, black, blue and yellow. The medical waste in blue color bin can be used for recycling it does not contain any harmful wastes and it is send to recycling unit, the waste is shredded into small particles and after sterilizing we can able to make new things.

Abstract: The second-order system is the lowest-order system capable of an oscillatory response to a step input. The response depends on whether it is an overdamped, critically damped, or underdamped second order system. Here we will find out transient response specifications of second order system. This system can be implemented using MATLAB software. But MATLAB software requires licence. In this paper, second order system is implemented using Scilab software. Scilab is an open source software and therefore the responses of second order system is implemented using Scilab.

Keywords: Scilab, response, damping, specifications, transient

Abstract: This paper concentrates on the fault ride-through capability of a Doubly Fed Induction Generator (DFIG) - based wind turbine using a Dynamic Voltage Restorer (DVR). The voltage variations from normal operating range due to faults may lead to improper disconnection of wind turbines, so the DVR is included to protect wind turbines from voltage disturbances. DVR can compensate the faulty line voltage, while the DFIG wind turbine can continue its nominal operation as demanded in actual grid codes. In this paper, the Simulation results for a 2MW wind energy conversion turbine are presented for without DVR and with DVR for L-G fault (asymmetrical grid fault) and L-L-L fault (symmetrical grid fault). The results clearly show that there is improvement in stator voltage, stator and rotor currents, and active and reactive powers when wind turbine is driven with DVR.

Abstract: Cell splitting in mobile communication is the process in which the bigger cells split up into smaller ones. In mobile communication we use cell splitting so that we can expand the capacity of the system. Cell splitting also helps to increase the number of channels. Whenever there is a bigger network for any area, the number of mobile users also increases.This system can be implemented using MATLAB software. But MATLAB software requires licence. In this paper, cell splitting is implemented using Scilab software. Scilab is an open-source software and therefore cell splitting implemented using Scilab.

Keywords: Scilab, Frequency reuse, cell splitting, cell.

Abstract: Numerous compression strategies have been developed as a result of the work of different researchers. It has been observed that a signal's entropy has an impact on its compressibility. If there are few coefficients in the energy distribution, compressibility is high. This paper focused on peak to average power ratio (PAPR) reduction scheme for OFDM system. OFDM has several properties which make it an attractive modulation scheme for high speed transmission. The main drawback of OFDM is high PAPR. The high PAPR causes the interference and degraded the performance of the system while OFDM signal pass through the amplifier. Here a simple scheme, clip and filter is used to reduce the PAPR of OFDM system. The compressed signal is transmitted and received using OFDM system. This process is carried out using Software Defined Radios (USRP-SDR)

Keywords: NISDR, PAPR, clipping and filtering method, partial transmit sequence technique and selective mapping technique.
