system promises to offer end user “pay as go” model. To meet the expected quality requirements of users, cloud
computing need to offer differentiated services to users. QoS differentiation is very important to satisfy

Score based deadline constrained workflow scheduling algorithm for cloud systemsijccsa
Cloud Computing is the latest and emerging trend in information technology domain. It offers utility- based
IT services to user over the Internet. Workflow scheduling is one of the major problems in cloud systems. A
good scheduling algorithm must minimize the execution time and cost of workflow application along with
QoS requirements of the user. In this paper we consider deadline as the major constraint and propose a
score based deadline constrained workflow scheduling algorithm that executes workflow within
manageable cost while meeting user defined deadline constraint. The algorithm uses the concept of score
which represents the capabilities of hardware resources. This score value is used while allocating
resources to various tasks of workflow application. The algorithm allocates those resources to workflow
application which are reliable and reduce the execution cost and complete the workflow application within
user specified deadline. The experimental results show that score based algorithm exhibits less execution
time and also reduces the failure rate of workflow application within manageable cost. All the simulations
have been done using CloudSim toolkit.
LOAD BALANCING ALGORITHM ON CLOUD COMPUTING FOR OPTIMIZE RESPONE TIMEijccsa
To improve the performance of cloud computing, there are many parameters and issues that we should consider, including resource allocation, resource responsiveness, connectivity to resources, unused resources exploration, corresponding resource mapping and planning for resource. The planning for the use of resources can be based on many kinds of parameters, and the service response time is one of them.
The users can easily figure out the response time of their requests, and it becomes one of the important QoSs. When we discover and explore more on this, response time can provide solutions for the distribution, the load balancing of resources with better efficiency. This is one of the most promising
research directions for improving the cloud technology. Therefore, this paper proposes a load balancing algorithm based on response time of requests on cloud with the name APRA (ARIMA Prediction of Response Time Algorithm), the main idea is to use ARIMA algorithms to predict the coming response time, thus giving a better way of effectively resolving resource allocation with threshold value. The experiment
result outcomes are potential and valuable for load balancing with predicted response time, it shows that prediction is a great direction for load balancing.

Energy Efficient Heuristic Base Job Scheduling Algorithms in Cloud ComputingIOSRjournaljce
Cloud computing environment provides the cost efficient solution to customers by the resource provisioning and flexible customized configuration. The interest of cloud computing is growing around the globe at very fast pace because it provides scalable virtualized infrastructure by mean of which extensive computing capabilities can be used by the cloud clients to execute their submitted jobs. It becomes challenge for the cloud infrastructure to manage and schedule these jobs originated by different cloud users to available resources in such a manner to strengthen the overall performance of the system. As the number of user increases the job scheduling become an intensive task. Energy efficient job scheduling is one constructive solution to streamline the resource utilization as well as to reduce the energy consumption. Though there are several scheduling algorithms available, this paper intends to present job scheduling based on two Heuristic approaches i.e. Efficient MQS (Multi-queue job scheduling) and ACO (Ant colony optimization) and further evaluating the effectiveness of both approaches by considering the parameter of energy consumption and time in cloud computing.

Scheduling Divisible Jobs to Optimize the Computation and Energy Costsinventionjournals
ABSTRACT : The important challenge in cloud computing environment is to design a scheduling strategy to handle jobs, and to process them in a heterogeneous environment with shared data centers. In this paper, we attempt to investigate a new analytical framework model that enables an existing private cloud data-center for scheduling jobs and minimizing the overall computation and energy cost together. Our model is based on Divisible Load Theory (DLT) model to derive closed-form solution for the load fractions to be assigned to each machines considering computation and energy cost. Our analysis also attempts to schedule the jobs such a way that cloud provider can gain maximum benefit for his service and Quality of Service (QoS) requirement user’s job. Finally, we quantify the performance of the strategies via rigorous simulation studies.

LOAD BALANCING ALGORITHM TO IMPROVE RESPONSE TIME ON CLOUD COMPUTINGijccsa
Load balancing techniques in cloud computing can be applied at different levels. There are two main
levels: load balancing on physical server and load balancing on virtual servers. Load balancing on a
physical server is policy of allocating physical servers to virtual machines. And load balancing on virtual
machines is a policy of allocating resources from physical server to virtual machines for tasks or
applications running on them. Depending on the requests of the user on cloud computing is SaaS (Software
as a Service), PaaS (Platform as a Service) or IaaS (Infrastructure as a Service) that has a proper load
balancing policy. When receiving the task, the cloud data center will have to allocate these tasks efficiently
so that the response time is minimized to avoid congestion. Load balancing should also be performed
between different datacenters in the cloud to ensure minimum transfer time. In this paper, we propose a
virtual machine-level load balancing algorithm that aims to improve the average response time and
average processing time of the system in the cloud environment. The proposed algorithm is compared to the
algorithms of Avoid Deadlocks [5], Maxmin [6], Throttled [8] and the results show that our algorithms
have optimized response times.
REAL-TIME ADAPTIVE ENERGY-SCHEDULING ALGORITHM FOR VIRTUALIZED CLOUD COMPUTINGijdpsjournal
Cloud computing becomes an ideal computing paradigm for scientific and commercial applications. The
increased availability of the cloud models and allied developing models creates easier computing cloud
environment. Energy consumption and effective energy management are the two important challenges in
virtualized computing platforms. Energy consumption can be minimized by allocating computationally
intensive tasks to a resource at a suitable frequency. An optimal Dynamic Voltage and Frequency Scaling
(DVFS) based strategy of task allocation can minimize the overall consumption of energy and meet the
required QoS. However, they do not control the internal and external switching to server frequencies,
which causes the degradation of performance. In this paper, we propose the Real Time Adaptive EnergyScheduling (RTAES) algorithm by manipulating the reconfiguring proficiency of Cloud ComputingVirtualized Data Centers (CCVDCs) for computationally intensive applications. The RTAES algorithm
minimizes consumption of energy and time during computation, reconfiguration and communication. Our
proposed model confirms the effectiveness of its implementation, scalability, power consumption and
execution time with respect to other existing approaches.
Cloud computing is the fastest emerging technology and a novel buzzword in the field of IT domain that offer distinct services, applications and focuses on providing sustainable, reliable, scalable and virtualized resources to its consumer. The main aim of cloud computing is to enhance the use of distributed resources to achieve higher throughput and resource utilization in large-scale computation problems. Scheduling affects the efficiency of cloud and plays a significant role in cloud computing to create high performance environment. The Quality of Service (QoS) requirements of user application define the scheduling of resources. Numbers of researchers have tried to solve these scheduling problems using different QoS based scheduling techniques. In this paper, a detail analysis of resource scheduling methodology is presented, with different types of scheduling based on soft computing techniques, their comparisons, benefits and results are discussed. Major finding of this paper helps researchers to decide suitable approach for scheduling user’s applications considering their QoS requirements.

Recently, lot of interest have been put forth by researchers to improve workload scheduling in cloud platform. However, execution of scientific workflow on cloud platform is time consuming and expensive. As users are charged based on hour of usage, lot of research work have been emphasized in minimizing processing time for reduction of cost. However, the processing cost can be reduced by minimizing energy consumption especially when resources are heterogeneous in nature; very limited work have been done considering optimizing cost with energy and processing time parameters together in meeting task quality of service (QoS) requirement. This paper presents cost and performance aware workload scheduling (CPA-WS) technique under heterogeneous cloud platform. This paper presents a cost optimization model through minimization of processing time and energy dissipation for execution of task. Experiments are conducted using two widely used workflow such as Inspiral and CyberShake. The outcome shows the CPA-WS significantly reduces energy, time, and cost in comparison with standard workload scheduling model.
Intelligent Workload Management in Virtualized Cloud EnvironmentIJTET Journal
Abstract— Cloud computing is a rising high performance computing environment with a huge scale, heterogeneous collection of self-sufficient systems and elastic computational design. To develop the overall performance of cloud computing, through the deadline constraint, a task scheduling replica is traditional for falling the system power utilization of cloud computing and recovering the yield of service providers. To improve the overall act of cloud environment, with the deadline constraint, a task scheduling model is conventional for reducing the system performance time of cloud computing and improving the profit of service providers. In favor of scheduling replica, a solving technique based on multi-objective genetic algorithm (MO-GA) is considered and the study is determined on programming rules, intersect operators, mixture operators and the scheme of arrangement of Pareto solutions. The model is designed based on open source cloud computing simulation platform CloudSim, to obtainable scheduling algorithms, the result shows that the proposed algorithm can obtain an enhanced solution, thus balancing the load for the concert of multiple objects.

The development in the field of cloud webserver management for the execution of the workflow and meeting the quality-of-service (QoS) prerequisites in a distributed cloud environment has been a challenging task. Though, internet of things (IoT) of work presented for the scheduling of the workflow in a heterogeneous cloud environment. Moreover, the rapid development in the field of cloud computing like edge-cloud computing creates new methods to schedule the workflow in a heterogenous cloud environment to process different tasks like IoT, event-driven applications, and different network applications. The current methods used for workflow scheduling have failed to provide better trade-offs to meet reliable performance with minimal delay. In this paper, a novel web server resource management framework is presented namely the reliable and efficient webserver management (REWM) framework for the edge-cloud environment. The experiment is conducted on complex bioinformatic workflows; the result shows the significant reduction of cost and energy by the proposed REWM in comparison with standard webserver management methodology.

Cloud computing became a popular technology which influence not only
product development but also made technology business easy. The services
like infrastructure, platform and software can reduce the complexity of
technology requirement for any ecosystem. As the users of cloud-based
services increases the complexity of back-end technologies also increased.
The heterogeneous requirement of users in terms for various configurations
creates different unbalancing issues related to load. Hence effective load
balancing in a cloud system with reference to time and space become crucial
as it adversely affect system performance. Since the user requirement and
expected performance is multi-objective use of decision-making tools like
fuzzy logic will yield good results as it uses human procedure knowledge in
decision making. The overall system performance can be further improved by
dynamic resource scheduling using optimization technique like genetic

A Review on Scheduling in Cloud Computingijujournal
Cloud computing is the requirement based on clients that this computing which provides software,
infrastructure and platform as a service as per pay for use norm. The scheduling main goal is to achieve
the accuracy and correctness on task completion. The scheduling in cloud environment which enables the
various cloud services to help framework implementation. Thus the far reaching way of different type of
scheduling algorithms in cloud computing environment surveyed which includes the workflow scheduling
and grid scheduling. The survey gives an elaborate idea about grid, cloud, workflow scheduling to
minimize the energy cost, efficiency and throughput of the system
Cloud computing gives on-demand access to computing resources in
metered and powerfully adapted way; it empowers the client to get access to
fast and flexible resources through virtualization and widely adaptable for
various applications. Further, to provide assurance of productive
computation, scheduling of task is very much important in cloud
infrastructure environment. Moreover, the main aim of task execution
phenomena is to reduce the execution time and reserve infrastructure;
further, considering huge application, workflow scheduling has drawn fine
attention in business as well as scientific area. Hence, in this research work,
we design and develop an optimized load balancing in parallel computation
aka optimal load balancing in parallel computing (OLBP) mechanism to
distribute the load; at first different parameter in workload is computed and
then loads are distributed. Further OLBP mechanism considers makespan
time and energy as constraint and further task offloading is done considering
the server speed. This phenomenon provides the balancing of workflow;
further OLBP mechanism is evaluated using cyber shake workflow dataset
and outperforms the existing workflow mechanism.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric

Abstract: Cloud computing is a new design structure for large, distributed data centers. Cloud computing
system promises to offer end user “pay as go” model. To meet the expected quality requirements of users, cloud
computing need to offer differentiated services to users. QoS differentiation is very important to satisfy
different users with different QoS requirements. In this paper, various QoS based scheduling algorithms,
scheduling parameters and the future scope of discussed algorithms have been studied. This paper summarizes
various cloud scheduling algorithms, findings of algorithms, scheduling factors, type of scheduling and
parameters considered.
Keywords- Cloud Scheduling, algorithms, Quality of service (QoS), Qda scheduling algorithm, Improved Cost
Based, PAPRIKA, ANT Colony, Cmultiqosschedule algorithm, SHEFT Workflow , Job scheduling algorithm
based on berger model.
I. Introduction
Cloud computing is the rising techNology that delivers infrastructure as a service [IaaS], software as a
service[SAAS], platform as a service[PAAS] [1]. Cloud computing began to develop at end of 2007. It allows
customers to use application without buying any software and hardware and access the files at any computer
using internet. Cloud computing has become an interesting way of changing the whole computing through
internet. Cloud computing is a model that combines various resources from data center into outside services.
Scheduler for cloud computing checks the availability of processing resources on which task should be allotted.
Service providers ensure that income is utilized to their fullest so that resource power is Not left unused.
Scheduling is a critical problem in Cloud computing, because a cloud provider has to serve many users
according to their different needs.
Scheduling in cloud computing is of various types: task scheduling, workflow scheduling, resource
scheduling, job scheduling etc. Many researchers proposed various scheduling algorithms to achieve load
balancing and fairness among users. Because of different QoS parameters like cost, waiting time, execution
time, trust etc., scheduling in cloud computing is different from other scheduling environment like grid and
distributed scheduling. The demand of resources changes dynamically and scheduling becomes very difficult.
QoS is the collective effort of service performance, which determines the degree of user satisfaction for services
[2]. The cloud computing environment provides a different platform by creating a virtual machine that assists
users in accomplishing their jobs within a reasonable time and cost effectively without sacrificing the quality of
the services [3]. The main task is to efficiently and reasonably allocate the user’s needs to available resources
according to the QoS from both cloud side and user side. The paper is organized as follows: section II gives a
review on some scheduling techniques based on different. QoS parameters, section III shows the comparison of
various algorithms by taking different parameters and future scope of discussed algorithms, section IV shows
the metrics of various parameters and section V concludes the paper.
II. Related work
A. QDA scheduling algorithm
Luzhang et.al [4] proposed a QDA scheduling algorithm using cloud workflow as a background.
Algorithm works on instance-intensive workflow scheduling optimization problem. By combining staggered
sub-deadline allocation criteria and differentiate tasks based on QoS preferences of users, QDA algorithm is
proposed. It takes many QoS parameters like time, cost, bandwidth, reliability, quantifies them with particular
value and use them in QoS based sub-deadline allocation algorithm to meet complete QoS user satisfaction.
QDA algorithm simulates on cloudsim new program function called BindcloudToVmByDeadline. By taking
QoS utility function into account, QDA algorithm performs better in case of execution time, user satisfaction
and load balancing.

DOI: 10.9790/0661-17633538 www.iosrjournals.org 36 | Page
B. Improved Cost Based Scheduling algorithm
In [5] paper author proposed the approach that is improved cost-based scheduling algorithm. It
measured computation performance and resource cost. It also increased execution data transfer ratio by
combining the tasks.
C. PAPRIKA
Hilda Lawrance and Dr. Salaja Silas[6] proposed a task based scheduling of resources called
potentially all pair-wise rankings of all possible alternatives (PAPRIKA). By taking various QoS parameters
into account, tasks and resources are arranged according to user satisfaction and PAPRIKA method. According
to resources and tasks QoS parameter values, resources and Task matrix is created respectively. PAPRIKA
method is based on overall ranking of all possible alternative values. Resource priority is calculated by
allocating a threshold value to all QoS parameters, comparing all resources pair-wise with threshold value and
finding priority of each resource. Task from task line is taken and allocate tasks to resources according to the
user satisfaction. PAPRIKA method proves better result in case of task completion time and resource utility rate.
Resource utility rate of PAPRIKA method is higher when compare with S-CSRSA[11] algorithm.
D. ANT Colony Algorithm
The author proposed a poised Ant colony algorithm [7] which uses a pseudo random proportional rule
to poise the integral organization load while completing all the jobs at hand as soon as possible according to the
environmental status. This algorithm balances the workload as well as minimizing the make span.
E. CMultiQoSSchedule algorithm
Due to restriction that most scheduling algorithm takes only time and cost as QoS parameters, Wenjuan
Li et.al[8] proposed a new Novel based scheduling algorithm based on trust values. This approach used the trust
parameter for workflow scheduling in cloud. Novel workflow scheduling is divided into two stages that is macro
and micro. Trust value is calculated from both provider side and user side. On cloud provider side, trust agents
manage the trust relationship by differentiating trust domains according to existing cloud platform. Cloud
customers take help of intermediate institution to manage trust relationships. Using trust mechanism author
proposed a single workflow scheduling algorithm under time and cost constraints. It also introduced fuzzy
clustering method to classify workflow process. Cloudsim tool with extended features is used to simulate
results. This approach achieve high execution success rate, less completion time and more user’s satisfaction
when compared with dynamic level scheduling(DLS), modified critical path(MCP) and berger model. It
provides more success rate by eliminating dishonest providers. To use this model in actual cloud platform, its
efficiency and effectiveness should test.
F. SHEFT Workflow Scheduling Algorithm
This paper [9] proposed the SHEFT (Scalable HEFT) scheduling algorithm that helps increasing and
decreasing the number of resources at runtime. It provides facility to resources to scale at runtime, outperforms
in optimizing workflow execution time. It scheduled a workflow in a cloud environment elastically. There was
optimized execution time for the workflow.
G. Job scheduling algorithm based on berger model
Hongbo Yu [10], proposed a scheduling algorithm based on Berg Model that adapts to
commercialization and virtualization features of cloud environment. People element analysis theory is applied to
establish dual fairness constraints and efficiency. User’s demand of resources is based on various QoS based
parameters. Firstly, selection of resources is done on some expected constraints and then fair judgement
constraints allocate resources to tasks. Proposed algorithm reflects better fairness of user tasks. In future, it
should experimentally implement using Berg model.

V. Conclusion
Scheduling is a major factor in cloud environment. As shown in paper scheduling depends upon
various QoS parameters. This paper gives review on various QoS based task scheduling algorithms and the
future work to be done on that algorithms. The existing scheduling algorithm considered as topic of research and
can be used to introduce more efficient and improved performance of algorithms based on parameters like trust
value, execution rate, cost of the communication, speed and success rate.
