Elastic neural network method for load prediction in cloud computing gridIJECEIAES
Cloud computing still has no standard definition, yet it is concerned with Internet or network on-demand delivery of resources and services. It has gained much popularity in last few years due to rapid growth in technology and the Internet. Many issues yet to be tackled within cloud computing technical challenges, such as Virtual Machine migration, server association, fault tolerance, scalability, and availability. The most we are concerned with in this research is balancing servers load; the way of spreading the load between various nodes exists in any distributed systems that help to utilize resource and job response time, enhance scalability, and user satisfaction. Load rebalancing algorithm with dynamic resource allocation is presented to adapt with changing needs of a cloud environment. This research presents a modified elastic adaptive neural network (EANN) with modified adaptive smoothing errors, to build an evolving system to predict Virtual Machine load. To evaluate the proposed balancing method, we conducted a series of simulation studies using cloud simulator and made comparisons with previously suggested approaches in the previous work. The experimental results show that suggested method betters present approaches significantly and all these approaches.

Scalable Distributed Job Processing with Dynamic Load Balancingijdpsjournal
We present here a cost effective framework for a robust scalable and distributed job processing system that
adapts to the dynamic computing needs easily with efficient load balancing for heterogeneous systems. The
design is such that each of the components are self contained and do not depend on each other. Yet, they
are still interconnected through an enterprise message bus so as to ensure safe, secure and reliable
communication based on transactional features to avoid duplication as well as data loss. The load
balancing, fault-tolerance and failover recovery are built into the system through a mechanism of health
check facility and a queue based load balancing. The system has a centralized repository with central
monitors to keep track of the progress of various job executions as well as status of processors in real-time.
The basic requirement of assigning a priority and processing as per priority is built into the framework.
The most important aspect of the framework is that it avoids the need for job migration by computing the
target processors based on the current load and the various cost factors. The framework will have the
capability to scale horizontally as well as vertically to achieve the required performance, thus effectively
minimizing the total cost of ownership

I. INTRODUCTION
These days’ people understand a lot more about high
availability, best practices and pattern. Over the past years it
has been observed that there are problems in handling the
load due to declined cost of hardware, advancement in
common technology, explosive growth of internet and need
of solving large scale problems. The question arises that
what basically load is? Load is the amount of request for
data performed by the user over the server.There is
anovergrowing need for data transfer on move. This drives
an urgent need to resolve Heavy overhead consumption in
routing issues. The resources in distributed computing
systems should be allocated to computational tasks. So as to
optimize some system performance parameters that
guarantee a user specified level of system performance.The
load balancing is concerned were resource allocation
policies to assign tasks to computing nodes. The primary
function of a load balancer is to keep your application on
running with no down time. It is invaluable tool for system
architecture and it has the benefit of being pretty simple to
understand.A local balancer is simply a device that sends
internet traffic to a group of application that serves with an
even load distribution. Load balancing improves the
distribution of workloads across multiple computing
resources. Load balancing is dividing theamount of work
that a computer has to do between two or more computes so
that more work gets done in the same amount of time and in
general all uses get served faster. Load balancing can be
implemented with hardware or software or both.
Server-side load balancer is usually a software program that
is listening on the port where external clients connect to
access services. The load balancer forwards requests to one
of the "backend" servers, which usually replies to the load
balancer. This allows the load balancer to reply to the client
without the client ever knowing about the internal
separation of functions. It also prevents clients from
contacting back-end servers directly, which may have
security benefits by hiding the structure of the internal
network and preventing attacks on the kernel's network
stack or unrelated services running on other ports.Some
load balancers provide a mechanism for doing something
special in the event that all backend servers are unavailable.
This might include forwarding to a backup load balancer, or
displaying a message regarding the outage.It is also
important that the load balancer itself does not become
a single point of failure. Usually load balancers are
implemented in high-availability pairs which may also
replicate session persistence data if required by the specific
application.[5]

Numerous scheduling algorithms are used by load balancers
to determine which back-end server to send a request to.
Simple algorithms include random choice or round
robinmore sophisticated load balancers may take additional
factors into account, such as a server's reported load, least
response times, up/down status (determined by a monitoring
poll of some kind), number of active connections,
geographic location, capabilities, or how much traffic it has
recently been assigned.An important issue when operating a
load-balanced service is how to handle information that
must be kept across the multiple requests in a user's session.
If the backend server has the information that is stored
locally on one backend server then subsequent requests
going to different backend servers would not be able to find
it. This stored information can be recomputed, in case load-
balancing a request to a different backend server just
introduces a performance issue.
II. EXISTING SYSTEM
The existing system worked on load balancing by using a
Dynamic Load Balancing Parallel Hash Join (LBJ)
algorithm. This algorithm is used for shared-nothing
hypercubecomputers.
Basically in this system, fragments get partitioned from a
relation who is initially horizontal. These fragments are
disjoint and are distributed among allthe processors. When a
join operation is performed, each processor firsthashes its
local portion of the relations into subbuckets. Theselocal
subbuckets are then stored back into the local disks.After
the subuckets are formed, the distribution ofthe data in each
bucket is computed, and the matchingsubbuckets are then
collected to their designated processor to form the
corresponding buckets by the use of a largest
subbucketretaining strategy to reduce communication
overhead. The gathering of the subbuckets is based on the
size of buckets to ensure balanced work load for each of the
processors during the join phase.Each processing node (PN)
on the hypercube is directlyconnected to each of its n
neighbors, where n = log, Nand N is the number of
processors. In this structure, eachprocessor is given a
unique n-bit binary address. Each bit givesthe coordinate of
that processor in the n-dimensional space.Thus, the
neighbors of the processors are those processorswhose
coordinates differ by exactly one bit position. Two PN's are
named paired nodes and the communication step is called a
pairing communication step.Overall the existing system
consists of the system environment which is a shared-
nothing hypercube multiprocessor computer and
therelations are horizontally partitioned into disjoint subsets
of the tuples and distributed across all the PN’s.

3.3 Dynamic scheduling algorithm.
Dynamic scheduling, as its name implies, is a method in
which the hardware determines which instructions to
execute, as opposed to a statically scheduled machine, in
which the compiler determines the order of execution. In
essence, the processor is executing instructions out of order.
Dynamic scheduling is akin to a data flow machine, in
which instructions don't execute based on the order in
which they appear, but rather on the availability of the
source operands. Of course, a real processor also has to take
into account the limited amount of resources available. Thus
instructions execute based on the availability of the source
operands as well as the availability of the requested
functional units. Dynamically scheduled machines can take
advantage of parallelism which would not be visible at
compile time. Dynamic priority scheduling is a type
of scheduling algorithm in which the priorities are
calculated during the execution of the system. The goal of
dynamic priority scheduling is to adapt to dynamically
changing progress and form an optimal configuration in
self-sustained manner. It can be very hard to produce well-

defined policies to achieve the goal depending on the
difficulty of a given problem.
In parallel computation, the scheduling and mapping tasks
is considered the most critical problem which needs High
Performance Computing (HPC) to solve it by breaking the
problem into subtasks and working on those subtasks at the
same time. The application sub tasks are assigned to
underline machines and ordered for execution according to
its proceeding to grantee efficient use of available resources
such as minimize execution time and satisfy load balance
between processors of the underline machine. The dynamic
scheduling algorithms allocate/reallocate resources at run
time.
3.4 Work done
Before using the load balancing software, the user will have
to first register on it. For this they will need to provide all
basic information and submit it. Once registration is done,
user get registered on website and now they can login using
user name and password entered while registration. This is
GUI which is visible to the user. While registration, various
validation are applied such as if male entered by user is
incorrect then registration form will not be accepted and a
message will be displayed that is entered mail is invalid.
Connectivity is established between front end and back end
using connection string so that the data entered by user will
get stored in SQL table. Whenever the file uploaded on any
of the sub server, then the count of that sub server will get
incremented by one. Likewise we will be able to find the
load that has been generated on each of the sub server. Once
the load is known for all sub servers, the task is assigned to
the server having lesser load. For assigning the task we are
using dynamic scheduling algorithm. The dynamic
scheduling algorithm work as follows:
1. Input task
2. Generate load list
3. CPU load in load list
4. Find minimum load in load list.
5. Assign task to respective server
6. Update the server to server load
While downloading a file, a file download window will be
displayed. Here all the sub server containing the uploaded
file will be displayed. The user can download the required
file from the respective server where the file was uploaded
previously.Data integrity is also maintained. If there is any
modification of data, changes in data or any update in data
the user will be notified with the size of file, date and time.
The user can download the modified version of the file if
data integration is done or else the original file can be
downloaded.
IV. LITERATURE SURVEY
In this paper, Hisao Kameda studied that job processing can
be shared by distributed computer system in the event of
overloads. This paper has considered two optimal policies
which dynamic and static. In these policies, job scheduling
is defined in order to minimize the system mean response
time. The main aim of this paper is to determine till what
extent the optimal dynamic load balancing policies
performs better than the static one by an exhaustive
numerical investigation on a model for which both the
policies are analytically studied. The overall mean response
time is minimized by both the policies. A comparison of the
performance of dynamic and static policies has been studied
in more sophisticated models. In these models there are
overheads which are considered, but the truly optimal
dynamic policy is not accurately obtained. Load balancing
policies have a purpose to improve the performance by
distributing the work load among more than one node.
Dynamic load balancing policies reacts to the current
system state and static load balancing policy depends on the
average behavior of the system[1].
In this paper, Katherine M. Bawngartner and Benjamin W.
Wah have explained a load balancing strategy for a
computer system which is connected by multi-access
broadcast network. The strategy that has been used in this
paper is to implement an efficient search technique for
finding stations with maximum and minimum work load by
using the existing broadcast capability of these networks. A
global scheduling strategy is studied in this paper, whose
objective is to find the maximum attainable performance of
such kind of strategy. A bus connection is common in many
local DCSs and workstations, so therefore a system with a
broadcast bus is chosen. This paper describes the proposed
strategy, the motivation of its development, its
implementation and its performance. The second part of this
paper describes a scheduling strategy. In this strategy the
workload is transferred from the loaded processor to the
minimally loaded processor. The detail studied of the
frequency of operation the technique for isolating the
processors, a characterization of load distribution and
performance based on simulations is done. The overview of
the scheduling problem on a broadcast bus is also under
seed in this paper. A broadcast bus is connected by a
multiple identical processor. Each processor can have
arrivals to the system or from the bus. Independent task can
be model by the jobs. The results are returned to the
originating processor if and only if jobs are migrated to a
processor across the bus after the execution is completed.
The queue, at each processor is finite: only a limited
number of jobs may be waiting for execution [2].

In this paper, Ming-Chang Huang & hossein Hosseini and
K. Vairavan have recommended a load balancing protocol
called fuzzy logic receiver, which uses fuzzy logic control
for load transfer. The nodes are located for load transfer
dynamically by a logical hierarchically structure on which
the protocol is based. The performance of the protocol is
better than the BID algorithm for the data is studied from
the simulation results shown in this paper and it also
showed that it is better than the Non-fuzzy logic receiver-
initiated protocol when utilization is less than 0.7 the
protocol has the same system performance Non-fuzzy logic
receiver-initiated protocol when system utilization is higher
than 0.7. The outcomes support the system architecture and
the protocol that are used in this paper results in better
system performance as compared to other conventional load
balancing methods [3].
In this paper, Kicn A. Hua (member of IEEE) and Jeffrey
X. W. Suthey have put forward a Dynamic Load Balancing
Parallel Hash Join (LBJ) algorithm for shared-nothing
hypercube computers. In this firstly a relation is
horizontally partitioned into disjoint fragments and then it is
distributed among all the processors. When a join operation
is been performed, each processor first hashes its local
portion of the relations into the sub-buckets. These sub-
buckets are then stored into the local disks. After the
formation of sub-buckets, the data that has been distributed
in each bucket can be computed, and the matching sub-
buckets are then received to their designated processor to
form the related buckets using the largest sub-bucket
retaining strategy in order to reduce communication
overheads. The collection of sub-buckets depends on the
size of the buckets that ensures balanced workload for each
of the processors during the join phase. In this paper, author
stated a load balancing scheme for the hypercube
interconnection topology. The technique that has been
proposed is based on a partition tuning strategy that takes
the advantage of the already balanced portion of the data
space. To keep the cost of communication low the data
transmission can be confined to the overflow areas [4].
In this paper, Anuradha Sharma and Seema Verma
examined that Grid computing is an extension of distributed
computing that includes coordinating and sharing of
computational power, storage of data and network resources
across dynamic and geographically dispersed organization.
To unite the power of widely distributed resources, and
provide non-trivial services to users is one of the
motivations of Grid computing that has been studied in this
paper. An efficient load balancing system is one of the
essential part of the Grid to achieve this goal. The rapid
growth in use of computer has lead in the increased number
of applications is also surveyed in this paper. These
applications make use of the shared hardware and software
resources (e.g. memory processor, files etc.) which
increased the amount of submitted job across internet. They
found a solution to the problem that can be solved if the
application is distributed across different computers in such
a way that the job response time and the overhead on a
single computer are reduced. Proper distribution of
applications across different available resources is termed as
load balancing. The paper describes that some algorithms
do not specify memory requirement of the jobs while giving
the jobs to particular resources and some algorithms do not
consider the cost for communication that cannot be
neglected. The requirement of memory is very important in
order to complete the execution of jobs at the selected
resources within the time limit in realizing a real Grid
system [5].
In this paper, R. Vaishnavi, Jose Anand and R. Janarthanan
have studied the drawbacks post by the previous Grid
systems on the data grids storage services, so they have
proposed the cryptographic protocol that is able to fulfil the
requirements for storage security related with a generic
desktop data grid scenario. This paper has proposed a
protocol that uses three basic mechanisms to complete its
goal: (A) symmetric cryptography and hashing, (B) an
information dispersal algorithm and (C) fragmentation
factor quantitative metric. The results that are received
define a strong relationship between the assurance of the
data at rest, the FF of the volunteer storage clients and the
number of fragments required to rebuild the original. This
paper defines the enhancement of the overall security of the
desktop data grid, using a protocol that uses three basic
techniques to cope with untrusted volunteer nodes
participating in these environments. The use of
cryptography and information dispersal algorithms is not
new for securing data and metadata in distributed systems
but the main contribution of this research paper consist of
enhancing the mechanisms with the adoption of the
fragmentation factor representing the guarantees offered by
the volunteer storage client to the grid user’s storage data
and the sensitivity of the data [6].
In this paper, a solution is proposed for dynamic load
balancing by Javad Mohammadzadeh, M- Hossein
Moeinzadeh, Sarah Sharifian-R, Leila Mahdavi. As the
nature of the problem is NP-hard the desired methods are
heuristic. A Simple Scheduling Method, Round Robin and
Genetic Algorithm are described as previous methods of
this problem so as to improve the results, a new
modification of Genetic Algorithm is explained. The
problem proposed in this paper is to schedule a number of

non-uniform tasks to a number of non-uniform processors
in order to minimize max-span and maximize processor
utilization. The non-uniform property of tasks and
processors means difference in size of tasks and
computational power of processors [7].
V. CONCLUSION
Previously it was observed that there were many problems
arising regarding the balancing of the load amongst the
computational resource.In our project we worked on this
project and came with a conclusion of developing a load
balancer. The main goal of the Load Balancing algorithm is
to distribute the jobs among processors to maximize
throughput, minimize total turnaround of jobs, to match the
application need with the available computing resources,
maintain stability, and resource utilization. Hence the load
balancer handles all the processes that will be handled same
time. Proper decision making will be done by toolkit for
load management and all the resources will be efficiently
used.This paper presents the allocation of tasks to the
computing nodes so that nodes evenly loaded.
