An Adaptable Security Framework for Wireless Sensor Networks
Authors: El Zouka Hesham A. 
Published: May 2018

The design of secureÂ and survivableÂ nodes is one of the most vital issues in designing energy-efficient protocols for wireless sensor network where the energy, memory and computational power of sensor nodes are limited. In this paper, some of the challenges facing the wireless sensor networks are discussed in attempting to prolong the battery lifetime of the nodes, and to secure the communication channel. While most of these attacks can be dealt with through cryptographic security protocols provided by key management schemes, there are always a few that manage to really cause problems. One such attack that is most common and significant in WSNs is cloning attack. In clone attack, the intruder tries to capture and compromise some nodes and inject them into several locations throughout the network in order to conduct other types of attacks. Moreover, if this attack is not detected early, then these replicated injected nodes will consume a large amount of the network resources. Several possible approaches are suggested to improve the security, authentication protocols, and key management schemes in WSNs.Â Furthermore, utilizing the existing security protocols in wireless sensor networks has led us to propose a secure framework which incorporates security protocols in a way that minimizes the energy consumption of the sensor nodes. Our algorithm ensures data confidentiality, node authentication, and data integrity while remaining within acceptable memory, time and energy constrains.

Embedded system use in smart house is very common now-a-days. Electrical device like TV, Computer, Mobile, Fan e.t.c. are very common for day to day life of everyone. These sorts of device are controlled manually by man or by remote control with different controller or different switch. As we are being more digitalized day by day and getting rid of any sorts of manual devices then we are more inclined to the digital controlling system.Â Developing countries are radically using this type of systems in a very large scale. We develop a system model that will help the developing smart house smarter. Our developed system works with the current electrical system. We developed the system that works automatically with the increase or decrease of temperature. If the temperature goes to 37Â° or more the fan runs with full speed the fan also run slower/faster when the temperature goes down/increase in every 2Â° and vice-versa. When the temperature is â‰¤ 20Â° itâ€™s automatically stops. It can also operate manually though it has a switch connected to motor.

Authors: Kadum Jaffar Emad , Fyath Raad Sami 
Published: May 2018

Distribution of wireless communication signals over implemented optical networks is a challenged task since the presence of wireless services may affect the performance of the existing wired ones. This paper addresses the possibility of integrating impulse radio-ultrawideband (IR-UWB) wireless services into implemented coherent optical orthogonal frequency division multiplexing (CO-OFDM) network. Simulation results are presented for the transmission of a 625Mb/s UWB Â signal with either 50Gb/s single-channel or three-channel OFDM system. Both Gaussian monocycle and 5th-orderÂ derivative Gaussian pulses are used to implement Â the UWB system with two modulation formats, namely ON-OFF keying (OOK) and biphase modulation (BPM).Â The simulation results reveal that the performance of the CO-OFDM channels is not affected in the presence of UWB signals.
3D from 2D for Nano images using images processing methods
Authors: Abousalem Zib ziab 
Published: May 2018

The scanning electron microscope (SEM) remains a main tool for semiconductor and polymer physics but TEM and AFM are increasingly used for minimum size features which called nanomaterials. In addition some physical properties such as microhardness, grain boundaries and domain structure are observed from optical and polarizing microscope which gives poor information and consequentially the error probability of discussion will be high. Thus it is natural to squeeze out every possible bit of resolution in the SEM, optical and polarizing microscopes for the materials under test. In our paper we will tackling this problem using different image processing techniques to get more clarify and sufficient information. In the suggested paper we will obtain set of images for prepared samples under different conditions and with different physical properties. These images will be analyzed using the above mentioned technique which starting by converting the prepared samples images (gray scale or colored images) to data file (*.dat) in two dimensional using programming. The 2D data will convert to 3D data file using FORTRAN programming. All images will subject to the generate filter algorithm for 3D data file. After filtering the 3D data file we can establish histogram, contours and 3D surface to analysis the image. Another technique will be prepared using Visual FORTRAN for steepest descent algorithm (SDA) which gives the vector map for the obtained data. Finally the depth from one single still image will be created and determine using OpenGL library under Visual C++ language, as well as, perform texture mapping. The quality of filtering depends on the way the data is incorporated into the model. Data should be treated carefully. From our paper we can analysis any part from any image without reanalysis the image, all size of the image as in this paper we take three samples with different size (256 * 256), (400 * 400), (510 * 510), this method decrees the cost of hardware and sample.
A Novel Approach Covert Channel for Secret Communications
Authors: Hadi Ali Hussein 
Published: May 2018

This paper presents a novel covert channel for secret communications. It implements a new application layer covert channel, by applying multimedia steganography techniques to hide secret messages. This new channel method (called Under Your Radar (UYR)) provides a stealthiness method for the communication channel and an efficient method for hiding messages, as proved by our investigations. Such a covert channel will be used for transferring secret messages in two phases. In phase one, the message characters will be embedded randomly into the pixels of video frames. The choice of pixels is dependent on finding an identical value of the character ASCII representation from one of the pixel channels. The positions of pixels will form the steganography key, which will be used later to extract the message. Also, the steganography key will be embedded in an image using the LSB steganography technique. In phase two, the secret message will be exchanged between the sender and the receiver by sharing the video along with the steganography key over a public service (e.g. a social network), which serves as the new covert communication channel. The experiments outcomes have showed an improvement on the success of the proposed covert channel in exchanging secret messages without rising suspicion by observers or detection tools.
Enhancing Cloud Computing Security by Using Pixel Key Pattern

Published: May 2018

Cloud is a term used as a metaphor for the wide area networks (like internet) or any such large networked environment. It came partly from the cloud-like symbol used to represent the complexities of the networks in the schematic diagrams. It represents all the complexities of the network which may include everything from cables, routers, servers, data centers and all such other devices. Cloud based systems saves data off multiple organizations on shared hardware systems. Data segregation is done by encrypting data of users, but encryption is not complete solution. We can do segregate data by creating virtual partitions of data for saving and allowing user to access data in his partition only. We will be implementing cloud security aspects for data mining by implementing cloud system. After implementing cloud infrastructure for data mining for cloud system we shall be evaluating security measure for data mining in cloud. We will be fixing threats in data mining to Personal/private data in cloud systems.Â Â

Published: May 2018

In order to increase the performance of computational algorithms in terms of efficiency of estimators, we tested new nonparametric estimators in fuzzy and cellular automata models.Â In particular, image de-noising algorithms exist to restore digital images corrupted by impulse noise.Â These algorithms may do poorly in many common cases, for example, when high contrast and sharp edges lead to outliers, spikes, or non-symmetric patterns for neighborhing pixels.Â This would stem from the choices of estimators in the algorithms. We investigated new nonparametric estimators and compared to existing methods in simulation study. We detected better performances of our new methods under various situations.

REGION GROWING IMAGE SEGMENTATION ON LARGE DATASETS USING GPU
Authors: Kaur Gurpreet , Jindal Sonika 
Published: May 2018

Image segmentation is an important image processing, and it seems everywhere if we want to analyze what inside the image. There are varieties of applications of image segmentation such as the field of filtering noise from image, medical imaging, and locating objects in satellite images and in automatic traffic control systems, machine vision in problem of feature extraction and in recognition. This paper focuses on accelerating the image segmentation mechanism using region growing algorithm inside GPU (Graphical Processing Unit). In region growing algorithm, an initial set of small areas are iteratively merged according to similarity constraints. We have started by choosing an arbitrary seed pixel and compare it with neighboring pixels. Region is grown from the seed pixel by adding in neighboring pixels that are similar, increasing the size of the region. When the growth of one region stops we simply choose another seed pixel which does not yet belong to any region and start again. This whole process is continued until all pixels belong to some region. If any of the segment makers has the fusion cost lower than the maximum fusion cost (a given threshold), it is selected to grow. Avoid information overlapping like two threads attempting to merge its segment with the same adjacent segment.Â Experiments have demonstrated that the proposed shape features do not imply in a significant change of the segmentation results, as long as the algorithmâ€™s parameters are properly adjusted. Moreover, experiments for performance evaluation indicated the potential of using GPUs to accelerate this kind of application. For a simple hardware (GeForce 630M GT), the parallel algorithm reached a maximum speed up of approximately 20-30% for different datasets. Considering that segmentation is responsible for a significant portion of the execution time in many image analysis applications, especially in object-oriented analysis of remote sensing images, the experimentally observed acceleration values are significant. Two variants of PBF (Parallel Best Fitting) and PLMBF (Parallel Local Mutual Best Fitting) have been used to analyze the best merging cost of the two segments. It has been found that the PLMBF has been performed better than PBF.Â It should also be noted that these performance gains can be obtained with low investment in hardware, as GPUs with increasing processing power are currently available on the market at declining prices. The parallel computational scheme is well suited for cluster computing, leading to a good solution for segmenting very large data sets.
Balancing Energy Consumption in Wireless Sensor Networks Using Biogeography Based Optimization Algorithm and Fuzzy Approach
Authors: Yasir Basim Abood , Li Yu , Hussien Aliaa , Wang Desheng 
Published: May 2018

Extending the lifetime of the energy constrained wireless sensor networks is a crucial challenge in wireless sensor networks (WSNs) research. When designing a WSN infrastructure Resource limitations have to be taken into account. The inherent problem in WSNs is unbalanced energy consumption, characterized by multi hop routing and a many-to-one traffic pattern. This uneven energy dissipation can significantly reduce network lifetime. This paper proposes a new routing method for WSNs to extend network lifetime using a combination of a fuzzy approach and Biogeography Based Optimization (BBO) algorithm.Â Determine an optimal routing path from the source to the destination by favoring the highest remaining battery power, and the lowest distance (minimum number of hops) to the sink. To demonstrate the effectiveness of the proposed method in terms of balancing energy consumption and maximization of network lifetime, we compare our approach with the BBO search algorithm and fuzzy approach using the same routing criteria. Simulation results demonstrate that the network lifetime is significantly increased by employing the proposed routing method.
Optimized Load Balancing Strategy In Cloud Computing : A Review
Authors: Kaur Parveen , Sachdeva Monika 
Published: May 2018

Now a days every organization is migrating towards cloud computing as cloud computing is considered being more flexible and scalable as compared to other technologies. The technology simply means to provide the computing resources and services through a network. This paper discusses the existing approaches for scheduling algorithms that can maintain the load balancing and provides better improved strategies through efficient job scheduling and modified resource allocation techniques. The load can be CPU load, memory capacity, delay or network load. Load balancing is the process of distributing the load among various nodes of a distributed system to improve both resource utilization and job response time while also avoiding a situation where some of the nodes are heavily loaded while other nodes are idle or doing very little work. Load balancing ensures that all the processor in the system or every node in the network does approximately the equal amount of work at any instant of time.

Published: May 2018

Secret sharing schemes are ideal for storingÂ highly sensitive data. A secret is divided into many parts and every participant gets his unique part. If we combine all of these parts and try regenerating the secret then it might be impractical, and therefore the threshold scheme is used. Shamirâ€™s secret sharing scheme supports the same. Here, some of the parts or all of them are required to reconstruct the secret. Any threshold number of parts are sufficient to reconstruct the original secret. The Admin has a set of files which are confidentiality and availability of data. Whenever a Client requests to access the files, the Admin performs authentication of the user through an encrypted and stored on multiple databases so as to achieve Authentication module, who makes use if Shamir's secret sharing concept. This is similar to the One Time Password (OTP) mechanism. If the Client is authentic, Admin grants him the decryption key and the Client can access the file. In this paper, we shall discuss all this in detail using which we can provide security, replication of data and authentication.Â
