Abstract:CPU scheduling is a process which allows one process to use the CPU while the execution of another process is on hold(in waiting state) due to unavailability of any resource like I/O etc, thereby making full use of CPU. The aim of CPU scheduling is to make the system efficient, fast and fair.The Objective of this paper is to improve the existing Round Robin Scheduling by reducing the individual process waiting time and also reduces average waiting time and turnaround time. In this paper we also compare the existing round robin scheduling algorithm with the proposed algorithm with the help of Gantt charts.

 

Keywords– CPU Scheduling, Round Robin Scheduling, Improvised Round Robin Scheduling, Waiting Time, Turnaround time.

Abstract: Job scheduling is an important process in cloud environment to schedule the tasks and to minimize resource utilization. Recently, a lot of research works have been designed for job scheduling using different data mining techniques. The efficiency of existing job scheduling techniques was lower due to misclassification results. In order to solve this limitation, Softmax Bootstrap Ensembled Multiclass Scheduling (SBEMS) Technique is proposed. The SBEMS Technique employs multiple learning algorithms to obtain better predictive performance for job scheduling in cloud environment. The SBEMS Technique is developed by combining Sofmax regression tree classification with boostrap aggregative ensemble method. The SBEMS Technique creates '𝑀' number of Softmax Regression Tree........

Abstract: The enhanced PGP Security that we are proposing is based only for digital signatures & encryption/decryption of the messages. The algorithm that is used here consists of asymmetric algorithm as RSA 4096 & the symmetric algorithm used is AES-256(Advance Encryption standard). Also we require hashing function in order to secure the digital signature as well as messages. Hence we use Whirlpool hashing function which is open source & is based on 512 block cipher that makes the application more powerful than the previously used.

Abstract: Internet has both brighter and darker side when it comes to information access. Authentication plays a major role in attempting authorized access to secured sections of web applications. Completely Automated Public Turing test to tell Computers and Humans Apart (CAPTCHA) is a security program used as non-reusable element for authentication purpose. Though there exist few robust CAPTCHA's like complex image CAPTCHA, iCAPTCHA and ReCAPTCHA they are to be used through CAPTCHA service provider(e.g.: Google) In some environments, a system is considered to be strong if the password is not transmitted to the verification process. This paper proposes two real-time authentication mechanisms namely cognitive CAPTCHA and honeypot generation for protecting the information being provided over internet.

Abstract: Privacy in distributed environments introduces new security challenges since two parties in a typical access control may not always belong to the same security domain. Therefore, protection of personal identifiable information (PII) throws a fresh challenge in privacy equation in this context. Customarily, the challenge is how to preserve privacy when two parties in different security domains are involved in access control, particularly in distributed environments. This paper presents the conceptualization of privacy in typical distributed context, to raise issues when two parties in access control requires to protect privacy sensitive information.

Abstract: Early study tries to use chatbot for counselling services. They changed drinking habit of who being consulted by leading them via intervene chatbot. However, the application did not concerned about psychiatric status through continuous conversation with user monitoring. Furthermore, they had no ethical judgment method that about the intervention of the chatbot. We argue that more reasonable and continuous emotion recognition will make better mental healthcare experiment. It will be more proper clinical psychiatric consolation in ethical view as well. This paper suggests a introduce a novel chatbot system for psychiatric counselling service. Our system understands content of conversation based on recent natural language processing (NLP) methods with emotion recognition. It senses emotional flow through the continuous observation of conversation. Also, we generate personalized counseling response from user input, to do this, we use additional constrains to generation model for the proper response generation which can detect conversational context, user emotion and expected reaction.

Abstract: One of the basic and challenging issues in the wireless sensor networks is energy consumption. They are consist of many small size sensor nodes that have limited memory and battery. The most of the node energy is used in during the transmit data in the network. Therefore, power consumption management in the sensor nodes is very important and has a big role in the network lifetime. The consumed energy to transmit data in sensor networks can be decreased by different techniques so one of the most effective method is organizing nodes in the form of clusters and selection of appropriate cluster heads. In this paper, the Bayesian method is used to select the cluster heads. Selection of nodes using the proposed method reduces the energy loss of nodes in data transmission and increasing network lifetime.

Abstract: Augmented reality is gaining more popularity and have been considered as a vital technology. A combination of AR and VR is known as Mixed Reality (MR).This concept is more complicated than augmented reality and virtual reality since it integrates the several types of technologies which includes advanced optics, sensors, and computing power. This allows users to visualize the real world and virtual world at same time, a high range of communication between users and computational device for manipulation of the surrounding information. We use SLAM technology to derive some particular application on AR/VR. SLAM technology will allow user the capability to arrange augmented concepts in real time space which gives the best creating scenario of overlying virtual images. We give a brief idea about SLAM technology using which user can clarify the concepts of localization and mapping. Among various techniques to implement SLAM technology we discuss Visual SLAM technology, which is more interested in AR/VR/MR aspects..

Abstract:Distributed Denial of service (DDOS) has the most dangerous economics damages DDoS Attacks have plagued the Internet, corporate websites, and networks for more than a decade. Although DDoS attacks aren't new, modern threats and tactics are more advanced than ever. DDoS attacks are occurring with increas-ing frequency and causing a great damage against a rapidly growing number of targets worldwide. The most difficult problem against the defense of the Distributed Denial of service attack is how to distinguish between the legitimate traffic and the real traffic? To protect ISP companies against such attack, an IPS system implementation are needed to detect and prevent flooding attack, as it is one of the challenging issue. This paper introduces the major attacks types and tools used by attacker and study the mitigation techniques by implementing snort as IPS system. Moreover, the paper examines various mechanisms of distributed denial of service attacks, its detection, and various approaches to handle these attacks.

Abstract: DBSCAN is a density based clustering algorithm which groups together data points of similar characteristics. It is based on two input parameters minpoints and epsilon. The disadvantage of DBSCAN algorithm is that it compares each point in the dataset with every other point in the dataset and resulting in runtime complexity of O(n2). In this paper, a new approach of finding clusters similar to the clusters formed by DBSCAN but with improved time complexity is introduced. A quantitative performance analysis of the new methodology, the Bisecting Min Max DBSCAN algorithm on the iris dataset proved that, not only is the algorithm faster than the traditional DBSCAN, but also gives good cluster quality
