INTRODUCTION Scheduling may be defined as a technique that is used to allocate the specific work to the specific resource. The specific task or work can be expressed as virtual calculating elements like threads or data flows and these works are allocated to the hardware equipments like processors or expansion cards in order to complete the task. Usually the main focus of job scheduling technique is to trade off between different processors; on the other hand reduction of total processing time is also the field to be concerned. [1].In grid type scheduling two things need to be considered and that are job scheduling and resource scheduling. Firstly in job scheduling it is required to determine the suitable resource that can be allocated to the specific job [2]. Therefore the optimum processor needed to be determined so that the specific job can be allocated to it. In grid type scheduling two types of schedulers are required: local and grid. Firstly consider the local schedulers, these are the type of schedulers that perform in local region therefore they are highly efficient, quicker, and operates in identical environment and that's why completely take over the identical processors [3]. Grid type Schedulers are also referred as Meta type schedulers [4]. Further the scheduling technique can also be divided into two types: first is static scheduling and second is dynamic scheduling. In static type of scheduling, firstly the processes are allocated to appropriate processor and this particular processor will start execution of processes without any pause. In dynamic type of scheduling, the rescheduling of processes is permitted. It is possible to change the process execution on the basis of dynamic data gathered related to workload on processing units [5]. In the grid, various processing units are present to execute the process. Major objective is that it is required to identify the suitable processor to execute the particular job. Various techniques that can be used for job scheduling: Centralized scheduling: The type of scheduler used here is centralized scheduler. When all the processor is busy then it makes the performance of system efficient. Hierarchical scheduling: it also contains central type of scheduler and it will direct the process to the global type of scheduler. Decentralized scheduling: It does not contain any central type scheduler. It consists of distributed type of schedulers that cooperates each other in order to schedule the process [6]. 2. EXISTING JOB SCHEDULING ALGORITHM In recent years, there are number of job scheduling algorithms are existed which has been used by several researchers in their work. Some of the algorithms have mentioned below. 2.1 First Come First Serve Scheduling Algorithm(FCFS) This algorithm works as first in first out order where in the waiting queue number of jobs is available and FCFS executes the job which arrives at first in the queue. This algorithm provides several merits such as simple and easy executing whereas there is no requirement of any priority to the job [7]. On the flip side it has several demerits as it is non-preemptive, increases waiting and turnaround time and time consuming. The diagrammatically representation of FCFS algorithm has explained below where there are two queues such as ready and waiting. The tasks which are in waiting queue are waiting for their processing. The process which comes first will be processed first or wait until its turn.

Phishing is one of the serious offenses being committed. In Phishing hacker or group of hackers tries to acquire confidential information such as passwords or bank details etc in an attempt to steal users identity for financial gain or something much worse. In this paper, we are proposing an approach named “Phishing Prevention using server authentication” using which user can check the authenticity of the server with which he is willing to communicate. Here we are using visual cryptography along with general password authentication. In this scheme authentication via images is done. Here the keys being used could be single use keys or one for the time user wants to keep(depending on the will of the implementing party ). Under this scheme, the user chooses an image of his will. Then he performs cryptography operation over chosen image and converts it into shares (two at least). User uploads one share onto the trusted server...

Though beneficial but dangerous as the IoT (Internet of Things) nodes communicate over the unsecured wireless medium. The communication over unsecured wireless channel opened enormous ways for the illegitimate nodes to access the information and take control over the industrial machines despite being physically away. These threats can be overpowered with secure sessions; however, the exchange of keys to establish a secure session over a vulnerable channel becomes a challenge. Our approach (LKE) intend to solve this problem. LKE provides a lightweight key exchange platform to the legitimate IoT nodes and prohibit the unauthorized abuses. LKE uses lightweight Elliptic Curve Qu-Vanstone (ECQV) based implicit certificates for trust-building and generating keys among entities. All the messages exchanged are secured to prevent unauthorized access to information and preventing against forgery, replay, modification, impersonation and man-in-the-middle attacks, etc. The proposed scheme is tested on the AVISPA tool and results indicate its trustworthiness and strong resistivity against potential attacks. LKE has less computation and communication complexities due to the utilization of limited cryptographic operations which make it superior in comparison to other state-of-the-work.

Most of the organizations get customer reviews and feedbacks for their products for which they want quick reviews to action on them. Manual reviews would take a lot of time and effort and may impact their product sales, so to make it quick these organizations have asked their IT to leverage machine learning algorithms to process such text on a real-time basis. Gated recurrent units (GRUs) algorithms which is an extension of the Recurrent Neural Network and referred to as gating mechanism in the network helps provides such mechanism. Recurrent Neural Networks (RNN) has demonstrated to be the main alternative to deal with sequence classification and have demonstrated satisfactory to keep up the information from past outcomes and influence those outcomes for performance adjustment. The GRU model helps in rectifying gradient problems which can help benefit multiple use cases by making this model learn long-term dependencies in text data structures. A few of the use cases that follow aresentiment analysis for NLP. GRU with RNN is being used as it would need to retain long-term dependencies. This paper presents a text classification technique using a sequential word embedding processed using gated recurrent unit sigmoid function in a Recurrent neural network. This paper focuses on classifying text using the Gated Recurrent Units method that makes use of the framework for embedding fixed size, matrix text. It helps specifically inform the network of long-term dependencies. We leveraged the GRU model on the movie review dataset with a classification accuracy of 87%.

These are capable of detecting an event, processing the information, and transmitting that processed data. In WSN network there is a sink which conveys all information to the end user. The sink is placed anywhere in the target area. The nodes which are closer to the sink easily convey their message to it but the nodes which are at a great distance from it cannot directly forward their data to the sink, they have to send their data to the node which is closer to it than its neighbor forwards its data to sink. In this way the nodes which are closer to the sink have to send the data of the distant nodes along with their own so they get depleted in terms of energy, as their energy is used in sending their data along with the data of farther nodes. This problem is called HOT SPOT problem. In the proposed work the location of the sink node is optimized by using ACO. The simulation results of our proposed algorithm on MATLAB software demonstrated that it has reduced the network&#39;s energy consumption and improved other parameters like packet delivery rate.
