Edge is the important feature of image. The image edges contain rich knowledge which is very important for finding characteristic of image by object recognition. It is the commonly used technique in image processing.This paper shows a fuzzy rule based algorithm that is capable of finding edges effectively from grey scale images. This paper presents that kind of operators in computer vision applications. The gradient and standard deviation is used as input for fuzzy system. The algorithm in which fusion of hue component and principal component are implemented and then the results are compared with modified fuzzy based algorithm.Keywords

In a wireless network, there is a large number of mobile nodes that share the communication medium. The wireless network employs carrier sense based MAC algorithms such as Carrier Sensing Multiple Access (CSMA) and CSMA with Collision Avoidance (CSMA/CA) for efficient sharing of communication channel. But this method does not solve the problem of hidden nodes. Hidden nodes are those nodes that are out of range of other nodes or a group of nodes. The network throughput reduces because of packet collisions caused by these hidden nodes. To solve hidden node problem, the Request-To-Send (RTS) and Clear-To-Send (CTS) mechanism is widely used in wireless networks for reserving the channel to transmit data from source to destination. This paper is aimed to provide a survey on methodology and various algorithms and methods of implementing RTS/CTS mechanism in wireless networks.Keywords

As concerned with wireless networks, the communication is done through the radio links where chances of unauthorized user are more which consequently degrades the performance of network and result is more delay. Wireless networks are broadly classified into two broad categories: infrastructure mode and infrastructure less mode. Various protocols are defined under this which uses their different mechanism for detection and isolation of the wormhole attacks. In this paper some of the studies are defined on the basis of methods used for the detection and avoidance of attacks adhere to its use in it. As the numerous attacks may arise over network on MANET, their comparison has been discussed on the basis of techniques and their effects.
This paper intends to find out all the possible ways to detect and avoid the wormhole attack in the network. It may not lead to complete isolation of the attack but plays an important role to reduce the wormhole attack.

Due to the extensive range of applications the use of wireless sensor networks (WSNs) in past few years have increased a lot and it has become a hot research area now a days. One of the important issues in wireless sensor network is the intrinsic limited battery power in network sensor nodes. Since most of the energy is consumed by the transmission and reception, energy efficient routing protocol is required to enhance the lifetime of WSN. In this paper we presents the review of existing hierarchical routing protocol NEW LEACH and proposed a new approach that is better and more energy efficient than the existed approaches. In the proposed work, two enhancements are made. These enhancements are efficient cluster head replacement technique by using dynamic threshold value and the concept of upper threshold for sending data. Both NEW LEACH and Proposed protocol are simulated in MATLAB. The result shows that our proposed algorithm performs better than the NEW LEACH in terms of network lifetime.Keywords

Speckle noise is an intrinsic yet undesirable residual part of the medical ultrasound images, which considerably degrades the visual quality and limits the accuracy of automatic diagnostic techniques. Hence speckle suppression is an essential task before the examination and processing of the medical ultrasound images. Aiming at the problem of multiplicative speckle noise, an improved despeckled method is proposed in this paper, which is based on WaveletShrinkage_Guided filter. The proposed method used the Daubechies20 (d20) wavelet transformation to decompose the ultrasound images and an improved wavelet shrinkage algorithm to filter the high-frequency component. The wavelet coefficients of low-frequency sub-bands are filtered by an improved guided filter with varying regularization parameter and the inverse DWT is used to obtain the noise free image. Synthetic image and an ultrasound image experiments with the comparison of the Guided filter and WaveletShrinkage_Guided filter are carried out. The quantitative results of the proposed strategy show, that it outperforms the other despeckling methods in terms of favorable speckle suppression and edge preserving factors.Keywords

In the hyper-connected world, data has been playing a significant role in earthing the system of every domain that one can think of. But, it is undeniable fact that today data has prone to serious threats as it was never before, which has questioned the reliability, integrity as well as security of data. So, the technology has emerged that can mitigate all these issues, and that technology is none other than the technology residing at the heart of Bitcoin, The Blockchain.
Blockchain is one of the powerful technologies that has brought a revolution in conventional trading techniques. Conceptually, it is an open and distributed ledger that maintains an irrefutable database of records of all transactions or values that have been executed and shared peer-to-peer directly obsoleting the need for trust-worthy intermediatory in a secure, verifiable, moreover, in a permanent way alleviating the risk of fraud.
The main objective of this paper is not only to make blockchain a common business trading language but also to present its compelling applications in contrasting domains that are beyond currency rides, specifically in healthcare, politics, and its strategic implications in bridging strong economy using smart contracts that can revolutionize our digital global village.
