Survey on Secure Data Aggregation using Clustering Methods in WSN

Wireless Sensor Network is a group of specialized transducers with communication infrastructure for monitoring and recording conditions at diverse locations..It is constrained in terms of computation, communication,memoryand energy due to node failure, limited scalability and low battery power. Data aggregation is used to reduce communication overhead and energy expenditure in(WSNs). Data aggregation is a process of aggregating the sensor data using aggregation approaches. But the Data Aggregation techniques are prone to link and node failure, significant variation in readings and time consuming. In this survey, the cluster based data aggregation methods are discussed which overcome the issues in convectional data aggregation approaches. In clustering technique, a Cluster Head (CH) is selected which collects data from other sensor nodes in that cluster and forward aggregated data to the base station. Since cluster head is responsible for the aggregated data it is highly prone to malicious attacks. Therefore, different security frameworks which ensure data confidentiality and data integrity have also been surveyed

Performance of Chemical Vapor Deposited ZnO thin film as thermal interface material on optical properties of LED

Chemical Vapor Deposition (CVD) was used for the synthesis of ZnO thin film on Al substrates at various flow rates of O2 gas. ZnO thin film coated substrates were tested as thermal substrates on influencing the optical properties of high power LED at various operating currents. Spectrometer analysis showed that ZnO thin film prepared at 10 sccm O2 flow rate showed better performance by reducing the Color Correlated Temperature (CCT) at driving currents. CCT values were maintained with respect to driving currents by ZnO thin film interface at all driving currents than air interface (bare Al substrate). On luminous flux analysis, 5 sccm samples showed good performance on increasing the light of the give LED at all driving currents than bare Al boundary condition. The observed results were evidenced with help of particle size distribution analysis on all film surface using Nanoscope software. Overall, ZnO thin film deposited at low O2 flow rate would be an alternative to solid thin film interface material in electronic packaging applications

Online toll payment system using android application

Now a day’s android application are emerging popular day by day.Online toll payment system will be very useful for the passengers and also the payment can be done in online. The toll payment system consists of an application that generates QR-Scanner code that will be displayed on the mobile device after the payment is done. The application also gives notification to the passenger before 2km or 3km before reaching the toll booth. The generated QR code will be scanned through a camera mobile device which is connected to the mySql server. The code generated is compared with server data and will be verified

A brief review: Super-pixel based image segmentation methods

In this paper image segmentation techniques have been explored which uses super pixel as intermediate step along with fuzzy clustering methods. Superpixel segmentation is the process of partitioning an image into multiple segments called superpixels, which are homogeneous as in pixels inside every portion are comparable concerning certain attributes, for example, shading and surface. In spite of the fact that superpixelsegmentation as a rule yields over-sectioned results instead of item level fragments, it radically diminishes the quantity of picture primitives with insignificant loss of data and offers a simple approach to separate the probably picture objects with as few portions as could be expected under the circumstances. Likewise, since superpixelsegmentation gives a more characteristic and perceptually significant representation of the info picture, it is more helpful and powerful to concentrate area based visual elements utilizing superpixels. In order to get better segmentation the FCM use the GLCM features of turbo pixels instead of intensity values of pixels and hence help in decision making to put a particular turbo-pixel  into different fcm clusters. In the proposed work, we will explore these techniques in order to get better segmentation of different sections of the input images

Self-Tuning Service Provisioning for Decentralized Cloud Applications

Dynamic Proof of Storage (POS) could be a useful crypto graphical primitive that allows a client to inspect the honesty of outsourced documents and to with effectiveness overhaul the records amid a cloud server. A sensible multi-client distributed storage framework seeks the protected customer side cross-client de-duplication procedure that allows a client to skirt the transferring technique and acquire the ownership of the records now, once unique house proprietors of indistinguishable documents have transferred them to the cloud server. Considering the difficulties of structure differing qualities and individual label era, we tend to abuse a novel apparatus alluded to as Homomorphic recorded Tree (HAT). We have a tendency to demonstrate the assurance of our development and along these lines the hypothetical examination and trial comes about demonstrate that our development is temperate in watch

A Survey on breakdown vehicle alert system

Nowadays accidents are been highly viewed in all places frequently and causes demise of many people by making modest mistakes while driving near(school, hills, highways zones).Due to failure of engine which cause Breakdown of current conveyance. In which RF transmission plays a major role in this scenario with the avail of the RF frequency of an high pitch length which find the most proximate mechanic and police for back up and it additionally gives information as hazard alarm to all upcoming conveyances nearby on their dash board which is been installed as an LCD screen in the conveyance. The main objective is to design exhibit controller which gives peril information afore collision which is been adopted and played by RF transmission This paper presents an incipient design to control contingency of all automobiles The project is composed of these units: Alarm system and back up call. We have utilized a latest micro-controller for alerting far coming conveyance. The main motivation of our project is reduce the contingency rate in highways

Automatic extraction of domain specific hidden data for efficient response by search engine

As large amount of information is growing in web daily, lots of relevant data are available in the form of hypertext in web. Interested users can view publically index able pages of any web site and some information is hidden behind search forms and viewed after filling of the appropriate search interfaces. Lots of information is available behind the search interfaces known as hidden data. Right now unique web crawlers are utilizing distinctive methods for getting such profound data from the web and sent to the clients as per their problems. The purpose of fetching such deep information is to provide a large set of relevant response to the user according to their search query. In this paper a new technique suggested for automatic filling of search interfaces and then submits the form to the World Wide Web and collects the response in the form of web pages which will be send back after automatic submission of the form and then filter out relevant pages from these response pages according to the user specific query
