We propose an analytical model for multi-hop network to estimate total energy conservation to transfer the data packet over wireless multihop networks. The proposed model has been improved by means of energy efficiency which monitors the remaining hop energy. This model consider the communication parameter such as reliability, energy consumption, throughput, retransmissions of data packet & acknowledgement and communication delay. To implement our model, we used Matlab R2013a and Network simulator version 2.35. Our proposed simulation results has been compared with existing system models. © 2016 IEEE.

Diabetes is deliberate as one of the major contributors of crystallize infirmity and death in non-infectious diseases. Common method for determination of blood glucose concentration is using a self-monitoring glucose meter. This process requires pricking the finger and pry out the blood from the forearm and doing the chemical analysis with the help of disposable test strips. The pain and difficulty caused by this method have lead to the evolution of a noninvasive method. This method makes use of a near infrared sensor for transmission and reception of rays from fingertip. Near-infrared (NIR) is passing through the fingertip, before and after obstructing the flow of blood. By explicate the variation in received signal intensity achieved after reflection in both the cases, glucose present in blood can be predicted and wirelessly transmitted to a remote PC. The results show the potential of glucose measurement using Near-infrared. © 2015 IEEE.

Nanoparticle Lead sulfide was synthesized via simple chemical method and deposited on glass substrates at different substrate temperatures by thermal evaporation technique. The synthesized nanoparticle PbS was analyzed and confirmed by X-ray diffraction (XRD), Scanning electron microscopy SEM with EDX and thermogravimetry. The structural, optical, morphological and electrical properties of the deposited films were studied using XRD, UV-Vis, Raman, SEM with EDX, atomicforce microscopy AFM and Hall Effect measurements. The thickness of the deposited samples was measured using thickness profilometer. The Raman shift in the peak occurs toward lower energy with increasing substrate temperature deposited lead sulfide. The Z-scan study with open aperture was carried out at 532 nm using 5 ns laser pulse on the deposited films which shows that nonlinear absorption arises from saturable absorption process. The deposited PbS film exhibits p-type conductivity in Hall measurement. © 2014 World Scientific Publishing Company.

This paper proposed Fuzzified Particle Swarm Optimization and K-Harmonic Means algorithm (FPSO+KHM) for clustering the Electrical data systems. Thepartitioned clustering algorithms are more suitable for clustering large datasets. The K-Harmonic means algorithm is center based clustering algorithm and veryinsensitive to the selection of initial partition usingbuilt in boost function, but easily convergence in local optima. The proposed algorithm uses Fuzzified PSO and K-harmonic means algorithm to generate more accurate, robust, better clustering results, best solution in few number of iterations, avoid trapping in local optima and get faster convergence when compare to K-Harmonic Meansand hybrid PSO+ K-Harmonic Means algorithms. This algorithm is applied for two different set of IEEE bus electrical data systems. © 2013 IEEE.

Target localization and mobile node tracking problems in WSNs have been receiving considerable concentration recently, because of the requirements to achieve high localization accuracy, with the output of minimum cost. The drawback involved is the crisis of target tracking in Wireless Sensor Networks. Localization primarily refers to revealing of the spatial coordinates of a node. Target tracking deals with spatial coordinates discovery and movement tracking of a moving object. The mobile node location algorithms like weighted tracking methods and Arrival Time (AT) are insufficient for finding the location of the mobile device. The location estimation and weighted tracking method are mainly based on mobile target signal's Arrival Time (AT) measurement model. In this paper work, location tracking process can be achieved into two ways. At first part we find the location of the mobile node along with the extended weighted tracking method. This can be used to track the mobile device and to estimate the weight for the particular mobile node. Secondly, the concentration is towards the AT measurement model for measuring the signal arrival time. Finally, the proposed algorithm finds the location of the mobile device and improves the performance of the AT measurement model in different places. © 2015 IEEE.

Achieving efficient transmission by means of limited spectral resources has become crucial. Research in Orthogonal frequency-division multiplexing (OFDM) communication has risen in the last decade due to its ability to improve spectral efficiency and low-complexity implementation in frequency-selective fading environments. We address the problem of frequency synchronization in OFDM-based communications systems in the context of frequency-selective fading channels. By inserting null sub-carriers into a single OFDM block, frequency offsets are estimated. The paper clarifies issues related to the range of acquisition and identifiability of carrier frequency offset (CFO), and performance of estimators. Two novel MUSIC-based multi-CFO estimation methods were also investigated. The proposed methods enjoy low complexity to estimate multiple CFOs simultaneously, and they therefore enable PHY carrier aggregation to reduce hardware and computational complexity and to save synchronization time. Unlike conventional OFDM systems, multiple carrier frequency offsets (CFOs) must be taken into consideration for carrier-aggregated OFDM (CA-OFDM) communications. Several preambles have been constructed as pilots for individual component carriers. Using the preamble property, estimation methods for multiple CFOs have been proposed and investigated by using multiple signal classification (MUSIC) or a root-MUSIC algorithm. Simulation results prove that the proposed method can achieve good performance compared to previous systems. © Research India Publications.

This paper presents an Improved Particle Swarm Optimization (IPSO) and K- means algorithm for solving clustering problems for document and avoid trapping in a local optimal solution. Recent studies have shown that partitional clustering algorithms are more suitable for clustering large datasets. The K-means algorithm is the most commonly used partitional clustering algorithm because it can be easily implemented and is the most efficient one in terms of the execution time. The major problem with this algorithm is that it is sensitive to the selection of the initial partition and may converge to local optima. So here used Improved Particle Swarm Optimization (IPSO) +K-means document clustering algorithm. The proposed solution generates more accurate, robust and better clustering results when compared with K-means and PSO. IPSO algorithm is applied for four different text document datasets. The number of documents in the datasets range from 204 to over 800, and the number of terms range from over 5000 to over 7000 are take for analysis.

This paper demonstrates the automated traffic surveillance without any human intervention. The aim of this paper is to detect the traffic density and to work according to the traffic density. The traffic signal is structured with the camera which takes the snap of the road and the density is identified. Hence by this method the traffic is analyzed and the lights are transferred according to the traffic density. The number of objects present in the roads will be identified and those numbers are transmitted to the micro controller. The micro controller controls the traffic signal and the varied time is displayed in the 7 segment display. By this a dynamic approach is being followed to minimize the traffic delay and effectively commute even in heavy traffic scenarios. The primary aim is to eliminate waiting time, during peak hours. Some added advantage that are to be implemented are dealing at the time of unusual situation such as emergency vehicles like ambulances, patrol vehicles, fire engines etc., Time is varied in propotional to the traffic density. Using this model will eliminate unwanted waiting time in peak traffic hours. Single camera is used in determining density of the traffic which will reduce the cost of implementing. © 2014 IEEE.

Binding energy of an exciton in a wurtzite ZnO/Zn1-xMg xO strained quantum well is investigated theoretically in which the strong built-in electric field due to the spontaneous and piezoelectric polarizations is included. Numerical calculations are performed using variational procedure within the single band effective mass approximation by varying the Mg composition in the barrier. The exciton oscillator strength and the exciton lifetime for radiative recombination as functions of well width and Mg content have been computed. The internal field induced interband emission energy of strained ZnO/Zn1-xMgxO well is investigated with the various structural parameters. The total optical absorption coefficients and the changes of refractive index as a function of normalized photon energy in the presence of built-in internal field are analyzed. The result shows that the strong built-in electric field has influence on the oscillator strength and the recombination life time of the exciton. The optical absorption coefficients and the refractive index changes strongly depend on Mg composition. The occurred blue shift of the resonant peak due to the incorporation of Mg ions will give the information about the variation of two energy levels in the quantum well. © 2013 Elsevier B.V.
