They could provide bogus information to drivers, masquerade as a different vehicle, or use denial–of–service attacks to bring down the network. The
nefarious possibilities are mind–boggling–the stuff of sci–fi thrillers. But system security will undoubtedly become a paramount issue for transportation
systems with the successful deployment of integrated sensor based and cooperative vehicles.
Difference Between Distributed and Non–Distributed Systems
A distributed system is a computing system in which a number of components cooperate by communicating over a network.
Computer software traditionally ran in stand–alone systems, where the user interface, application 'business' processing, and persistent data resided in
one computer, with peripherals attached to it by buses or cables.
Inherent complexities, which arise from fundamental domain challenges: E.g., components of a distributed system often reside in separate address
spaces on separate nodes, so inter–node communication needs different mechanisms, policies, and protocols than those used for intra–node
communication in a stand–alone systems. Likewise, synchronization and coordination is more complicated in a distributed system since components
may run in parallel and network communication can be asynchronous and non–deterministic.

A Load Balancing Of Cloud Computing
A load balancing in cloud computing
Presentation
Distributed computing is a pulling in innovation in the field of software engineering. In Gartner 's report, it says that the cloud will convey changes to
the IT business. The cloud is changing our life by furnishing clients with new sorts of administrations. Clients get administration from a cloud without
paying consideration on the subtle elements. NIST gave a meaning of distributed computing as a model for empowering omnipresent, helpful,
on–interest system access to a mutual pool of configurable registering assets (e.g., systems, servers, stockpiling, applications, and administrations) that
can be quickly provisioned and discharged with negligible administration exertion or administration supplier association. More individuals pay
consideration on distributed computing. Distributed computing is productive and versatile however keeping up the strength of preparing such a
variety of employments in the distributed computing environment is an exceptionally complex issue with burden adjusting getting much consideration
for specialists. Since the occupation landing example is not unsurprising and the limits of every hub in the cloud contrast, for burden adjusting issue,
workload control is essential to enhance framework execution and look after security. Burden adjusting plans relying upon whether the framework
progress are essential can be either static or element. Static plans don 't utilize the framework data

Introduction
The continuous developments in information and communication technology have recently led to the appearance of distributed computing
environments, which comprise several, and different sources of large volumes of data and several computing units. The most prominent example of a
distributed environment is the Internet, where increasingly more databases and data streams appear that deal with several areas, such as meteorology,
oceanography, economy and others. The application of the classical knowledge discovery process in distributed environments requires the collection of
distributed data in a data warehouse for central processing. However, this is usually either ineffective or infeasible for the following reasons:
Storage Cost: It is obvious that the requirements of a central storage system are enormous. A classical example concerns data from the astronomy
science, and especially images from earth and space telescopes. The size of such databases is reaching the scales of exabytes (1018 bytes) and is
increasing at a high pace. The central storage of the data of all telescopes of the planet would require a huge data warehouse of enormous cost.
Communication Cost: The transfer of huge data volumes over network might take extremely much time and also require an unbearable financial cost.
Even a small volume of data might create problems in wireless network environments with limited bandwidth. Note also that

2.2 Platform as a Service(PaaS) PaaS is a development platform supporting the full "Software Lifecycle" which allows cloud consumers to develop
cloud services and applications (e.g. SaaS) directly on the PaaS cloud. Hence, SaaS only hosts completed cloud applications whereas PaaS offers a
development platform that hosts both completed and in–progress cloud applications and this is the only difference between SaaS and PaaS. It provides
the Run–time environment for application,development and deployment tools. 2.3 Infrastructure as a Service(IaaS) Cloud consumers directly use IT
infrastructures (processing, storage, networks and other fundamental computing resources) provided in the IaaS cloud. IaaS provides access to
fundamental resource such as physical machines,virtual machine and virtual storage. Amazon EC2 is the example of IaaS. 3 Deployment Model It
defines the type of access of the cloud. 3.1 Public Cloud– It allows system and services to be accessible to the general public. 3.2 Private Cloud–It
allows system and services to be accessible within an organisation. 3.3 Community Cloud–It allows system and services to be accessible to a group of
organisation. 3.4 Hybrid Cloud–It is the mixture of public and private cloud in which the critical activities are performed by private cloud and
non–critical activities are performed by public

Design of Multi-Agent Systems
Design of MAS In multi agent systems, there are four basic elements that collaborate to build the design of the system. The first element is agents,
which composes of group of autonomous agents that are considered the first and main part of the internal structure of the MAS design (Manzoni,
2009). Those agents are different in their numbers, method of response, smartness, dealing with problems, and internal architecture in general. Since
agents are necessary to interact and cooperate with each other to find a solution for common tasks or uncommon tasks as well, by communicating via
special messages that can arrive at any time. Hence, every one of these agents must be based on particular information in regarding of its actions and
making decisions (Wooldrige, 2009).
Communication and interaction is the second element of the MAS design, which is considered the central estate of any distributed system. However,
the interaction only happens when two or more agents share the same interest in regard to solving a problem. More than that, it is significantly
important in the system because of the difference between agents (Wooldrige, 2009). Agents that are in the same system interact in three different
ways: direct interaction (messages passing), through an intermediary agent, or through their environment. In more detail, they could be directly
communicated by sending messages when they understand each other's language. This means speaking the same language and using the same

Big Data And Bare Metal Essay
Big Data and Bare Metal TOC & EXEC SUMARY GOES HERE ONCE PAPER COMPLETED Introduction The industry is inundated with articles on
big data. Big data news is no longer confined to the technical web pages. You can read about big data in the mainstream business publications such as
Forbes and The Economist. Each week the media reports on breakthroughs, startups, funding and customer use cases. No matter your source for
information on big data, one thing they all have in common is that the amount of information an organization will manage is only going to increase;
this is what's driving the 'big data' movement. Organizations are relying on increasing amounts of information from a variety of sources, text, images,
audio, video, etc., to analyze, improve and execute their operations. These information sources are very large and complex and include data sets that
are structured and unstructured and today's processing applications are inadequate and expensive. Industries suffering from big data challenges include
the financial services, healthcare, retail, and communications, to name a few. These industries have been collecting data for years and with the advent
of the 'Internet of Things' data is growing exponentially. The challenge is how to make sense of this data and turn it into business value– analytics and
predictive analytics. The big data phenomenon is about collecting and storing large amounts of data and running analytics application ns on these large
datasets.

Advantages And Disadvantages Of Leader Election
2.3.1Introduction
Leader election is a primary problem in distributed systems where it is important to coordinate processes group communications and activities. The
leader is responsible for controlling and coordinating all communications between processes in the network, absence of the leader makes the overall
system inconsistent, and loses the system reliability. To keep the system consistent, it is necessary to nominate another leader, the LEA solves this
problem by deciding which process will be the new leader, and making it well–known to other processes [(Akbar, et al., 2006), (Refai, 2010)].

Each node in the system has a state variable indicates its state value, when the process is in ordinary operation and the leader is active in the system,
then state variable contains the normal value. Candidate state denotes that the leader is failed and the system is in the leader election process, leader
state is obtained by only one process when the election process terminates. Moreover, every node in the system possess a local variable lead, which
indicates the current leader of the system [(Yadav, et al., 2012), (Gajre, 2013), (Lynch, et al., 2012), (Stroller, 1997)].
It is necessary that, all processes have the same LEA. As well, any LEA must satisfy the following properties[(Murshed and Allen, 2012), (Stroller,
1997)]:
(a)Safety: The nodes in the system never disagree on the elected leader. All the nodes must recognize the same node as a leader, after the termination
of the election process, at most one node will be elected as a leader, and all other nodes must have the same lead variable value.
In other words, for all nodes i and j in the system, if statei = normal and statej = normal, then leadi =

Distributed Practice Vs Massed Practice Essay
Distributed and massed practices are two different practices that have been used for hundreds of years. According to the 28th volume of the Cahperd,
"massed practice is generally defined as practice that occurs without rest between trials (Burdick, 1977)." However, the definition of distributed practice
is, "a practice schedule in which the amount of rest between practice trials is long relative to the trial length (Schmidt, 1991)." Furthermore, according
to Memory: Foundations and Applications, distributed practice "means that practice is spread out over time (pg 392)." An example that the Memory:
Foundations and Applications book states, is that if you were a college student distributed practice means for you that you would let's say spend ... Show

For example, mass practice works right before an exam; it will definitely leave some information in your head for the test. The advantages as well as
the boundaries of massed and distributed practice are based on three things according to Cahperd, "fatigue, time constraints, and number of participants.
However, overall distributed practice is much more efficient because massed practice "promotes little long–term retention (Memory: Foundations and
Applications pg 392)."On the other hand distributed practice promotes availability, so that if you need the information at another time in your life
you will have it there at your disposal. Distributed practice creates "More total learning than does massed practice in less time (Memory:
Foundations and Applications pg 392)." Distributed practice leads you to be able to remember the information not only for the test but from years
from now, while "cramming" and massed practice only allows you to stress out while you learn for information that you will forget right after the test.
Key factors like this as well as spacing your time and having a better retention rate all lead to distributed practice producing better

Computer Science Laboratory ( Csl )
History:
The term ubiquitous computing was first articulated in 1988 by Mark Weiser in Xerox Palo Alto Research Centre (PARC) Electronics and Imaging
Laboratory (EIL).
In late 1987, Bob Sprague, Richard Bruce and other members of PARC and EIL put forward the idea of developing wall sized flat panelcomputer
displays from large area amorphous sheets. Its been believed that The wall display was used as input for scanning images and electronic pens. These
researchers anticipated such computer walls different than 'one person one–desktop computer ' convention. They got the idea of spreading computers
ubiquitously and invisibly through environment from this idea.
Concurrently, anthropologists from PARC (Lucy Suchman) were working on people 's behaviour towards technology and they figured out that the use
of technology is more situational than feature oriented. The vision concentrated on how the computers are embedded within the social framework of
daily activities and interplay of the same with physical environment.
From this background the first ubiquitous program emerged which was written at Computer Science laboratory (CSL). This program was used in
removing the drawbacks found in the personal computing. Drawbacks such as it needs continuous attention, it's detached from other activities and
other people around and has occupied our lives. Mark Weiser wanted to focus on human to human computing and put computation back into
environmental background.

Cloud, The And, And Systems Administration

exploration it uses all late accomplishments in virtualization, circulated processing, utility registering, and systems administration. It intimates an
administration arranged structural planning through offering virtual products also stages as administrations, diminished data innovation overhead for
the end–client, extraordinary adaptability, diminished aggregate expense of proprietorship, on interest administrations and numerous different things.
This paper is a short review built of readings with respect to "cloud" figuring and it tries to address, related examination points, challenges ahead...
This extraordinary issue investigates how cloud stages furthermore reflections, either without anyone else present or in blend with different stages, can
be viably used to help certifiable science and building applications. We particularly looked for articles that tended to algorithmic and application details,
programming models and frameworks, runtime frameworks and middleware, end–to–end application work processes, and encounters with true
applications. What is Cloud? Distributed computing is extremely popular. "It 's turned into the expression of the day," says Gartner senior expert Ben
Pring, reverberating a hefty portion of his associates. The issue is that (as with Web 2.0) everybody appears to have an alternate definition. As an issue
for the Internet, "the cloud" is a recognizable prosaism, yet when joined with "figuring," the importance gets greater and fuzzier. A few investigators
and sellers characterize distributed computing barely as a redesigned adaptation of utility processing: fundamentally virtual servers accessible over the
Internet. Others go extremely wide, contending anything you expend outside the firewall is "in the cloud," including ordinary outsourcing. Cloud
figuring comes into concentrate just when you ponder what IT generally needs: an approach to build limit or include capacities the fly without putting
resources into new base, preparing new work force, or permitting new programming. Distributed

Abstract
Prior to 1994, student registration at Newcastle University involved students being registered in a single place, where they would present a form which
had previously been filled in by the student and their department. After registration this information was then transferred to a computerised format. The
University decided that the entire registration process was to be computerised for the Autumn of ... Show more content on Helpwriting.net ...
The high availability requirement implies that the computerised registration system must be able to tolerate a 'reasonable' number of machine and
network related failures, and the consistency requirement implies that the integrity of stored data (student records) must be maintained in the presence
of concurrent access from users and the types of failures just mentioned. It was expected that most human errors, such as incorrectly inputting data,
would be detected by the system as they occurred, but some "off–line" data manipulation would be necessary for errors which had not been foreseen.
Tolerance against catastrophic failures (such as complete electrical power failure, or a fire destroying much of the University infrastructure) although
desirable, was not considered within the remit of the registration system. A solution that would require the University buying and installing specialist
fault–tolerant computing systems, such as Tandem [1] or Stratus [2] was not considered economically feasible. The only option worth exploring was
exploiting the University 's existing computing resources. Like most other universities, Newcastle has hundreds of networked computers (Unix
workstations, PCs, Macs) scattered throughout the campus. A solution that could make use of these resources and achieve availability by deploying
software–implemented fault–tolerance techniques certainly looked attractive.

Abstract Grid Computing resolves high performance computing and throughput issues through sharing of resources. These resources are heterogeneous
in nature and geographically distributed to develop large scale applications. Scheduling and Load balancing is one of the key ideas in grid
environment. For efficient scheduling, proper management of resources is required. This paper mainly presents Guided Ant Colony Optimization (ACO)
based Variable Neighborhood Search (GAVNS) algorithm which represents how to schedule an independent jobs on grid nodes in order to optimize the
schedule and load on nodes/servers. The performance of proposed algorithm is compared with existing Variable Neighborhood Search (VNS)
algorithm. Simulation results have shown that GAVNS performs better than VNS. Moreover, better makespan is achieved through this technique.

In this paper, with the help of the advanced automation and information technologies, a new hydraulic regulation method was proposed to achieve
on–site hydraulic balance for the district heating systems with distributed variable–speed–pumps configuration. The proposed method was comprised
of a new hydraulic model, which was developed to adapt the distributed variable–speed–pumps configuration, and a calibration model with genetic
algorithm. By carrying out the proposed method step by step, the flow rates of all distributed pumps can be progressively adjusted to their designated
values. A hypothetic district heating system with 2 heat sources and 10 substations was taken as a case study to illustrate the feasibility of the
proposed method. Two scenarios were investigated respectively. In Scenario I, the flow rate of one substation varied according to its heat demand and
the flow rates of other substations maintained their original values. And in Scenario II, the flow rates of all substations varied synchronously with the
same relative rate. The results of the both scenarios indicated that all pumps could be properly adjusted to their designated flow rates by the proposed
method with a high frequency adjustment resolution as 0.001 Hz. H. F. Deng et al.(2007)[35] Currently, increasingly transactional requests require

INTRODUCTION In recent years, with the popularity of service orientation architecture, many modern business applications adhere to the paradigms
of service orientation and service oriented architectures in order to create loosely coupled, modular software systems, which is easy to be maintained
and extended. In the field of automation and control systems, SOA–based flexibility is of even more interest, because it contributes not only to
substantial reductions of installation and setup costs. These costs are of particular importance since manufacturing plants again and again have to be
adapted to new products resulting in changes of the technical equipment and the process flows performed. One of the proposed approaches to achieve
this goal is the creation of new services by composing already existing ones, instead of building up everything from scratches. This is called process
service composition. Service composition facilitates the creation of innovative services that suit the end–user needs, with a reduced time to–market and
better component reuse.

cite{EffNonCoo–15} explore the impact of the nodes' non–forwarding and partially–forwarding actions on the performance of Epidemic, SnW, and
Prophet protocols in terms of the data delivery ratio and delay. The experimental results demonstrate that DTNs tolerate a high percentage of
non–cooperative nodes (20–40% or even 60%) without too much harm, even though they still utilize the other nodes' resources to deliver their own
messages. Meanwhile, synthetic random mobility models are most vulnerable to less cooperation that implies that DTNs are robust against the nodes'
non–cooperative behavior.... Show more content on Helpwriting.net ...
While the works above consider nodes' social–oblivious selfishness behavior, Bermejo textit{et al.} cite{EmpiricalAlturistic–13} study human
altruism in AppExp and WebExp applications with respectively 800 and 737 nodes considering the nodes' remaining battery level and social tie
information. The experiments show that nodes respectively exhibit 70% and 52% altruistic behavior in AppExp and WebExp when a minor credit (1
dollar) is awarded. Meanwhile, the nodes are not willing to relay data received from others when their remaining battery level is less than 10%. Xia
textit{et al.} cite{Sig4UDD–113} explore the impact of IS and SS nodes on social–based routing protocols under uncertain node cooperation. In
particular, a signaling game approach (Sig4UDD) is proposed where Bayesian Nash equilibrium and perfect Bayesian equilibrium are employed to
analyze the nodes' one–stage and multi–stage interactions (Fig. ref{Sig4UDDScheme}). Meanwhile, a belief system is established to help the nodes
predict the type of their encounters and decide whether to forward a message to them or not. The experimental results demonstrate that nodes in
Sig4UDD can effectively establish their beliefs based on their previous interactions that can decrease the transmission cost significantly while
improving the data delivery delay. Similar to cite{Sig4UDD–113}, Wang textit{et al.} cite{UserUncenrtainty2015}

several middleware services implemented in technologies like SAP–XI, TIBCO, Web methods 8.2, and BizTalk. My responsibilities included
monitoring applications, gateways and servers, managing tickets, bug fixing and roll out to productions. Direct interactions with the client taught me
how to organize, automate, and synchronize the support services and finally, how to build customer loyalty. Working on various EAI (Enterprise
Application Integration) technologies familiarized me well with the production support phase of the software development. Management and handling
of the gateways and servers, used by Intel for transactions worth millions of dollars, induced a deep sense of responsibility in me and gave the
confidence to manage big projects.
The undergraduate curriculum at Mukesh Patel School of Technology Management & Engineering (MPSTME) exposed me

Advantages And Disadvantages Of Grid Computing
This paper gives an overview about Grid Computing and the various key issues related to that.Today we are in the Internet world and everyone prefers
to get fast access to the Internet. The growth of the internet with various resources and high speed networks changes the society enormously. We can
improve the speed of the computer using Grid. This paper presents clearly the vision of the grid computing and the architecture of grid computing.The
advantages and the disadvantages of the grid computing has also been discussed.
1.Introduction
The grid vision is the computational power such as resources, power, data are readily available as electric power1.Grid allows the user to use these
resources efficiently and securely. Grid computing is an... Show more content on Helpwriting.net ...
The main services provided through utility grids are software and special equipments. For instance, the applications can be run on one machine and all
the users can send their data to be processed to that machine and receive the result back.Grid Computing will not come in reality unless it provides a
core of services ,reliability and enough usability1.
III. Advantages and Disadvantages
There is no need to have large number of SMP servers. It efficiently uses the idle resources. If there is any failure in one grid ,the grid environment
automatically uses the other resources. Easy to scalable. Jobs can be executed in parallel and increase the speed of the computation. Grid computing
consists of some disadvantages too. Some applications need to be modified in order to use this application in grid computing. The applications which
are not designed to use an MPI (Message Passing Interface) will have to revert to an SMP (Symmetric Multi–Processing). Grid computing requires an
advanced infrastructure like small servers, fast connections between the servers and the use of quality tools, software and skilled technicians to
manage the grid.This grid computing is also costly and security issues also need to be

There are also lack of some mechanisms to register and classify the participants carefully, such as the tracing and monitoring for them. In the following
section, we will analyze the challenge for the cloud computing security in deep. B. The challenge for the security in cloud computing
In cloud computing environment, many users participate in the CLOUD and they join or leave CLOUD dynamically.
Other resources in the cloud computing environments are the same too. Users, resources, and the CLOUD should establish the trustful relationship
among themselves. And they will be able to deal with the changing dynamically.
The CLOUD includes distributed users and resource from distributed local systems or organizes, which have different security policies. According to
this reason, how to build a suitable relationship among them is a challenge. In fact, the requirements for the security in cloud computing environment
have some aspects, including confidentiality. multiple security policy, dynamic of the services., the trust among the entities, dynamically building trust
domains.
In the next section, we will propose the mechanism of trusted computing platform and other related functions that aid to achieve the trusted cloud

In the past applications were monolithic, and were built on a single stack such as .Net or Java and ran on a single server. There is no way to get
around building distributed software in today's market. Just think about the software out there today. The market consist of many different variations of
architecture tier an application may have such as an UI tier, caching tier, application tier, and persistence tier such as SQL or table logging.
Multiple components may spread across machines today. Software will have associated dependencies and these component dependencies can be in
conflict. One component might be dependent on a certain DLL and another component for another one. Those two different versions might not run or

It will be wasteful to have the same execution environments even though they have different scale characteristics. Developers also deal with test and
production to move throughout the development life cycle.
Since developers are increasingly building distributed operating systems, the way to deal with complexity is using the concepts of containers.
Containers are a native OS construct that provide light weight isolation. In Linux there is a concept that is comprised of different sub–concepts. There
are namespaces that provide isolations for user database, processes and IP addresses. Think of a container as hosted on top of an Linux OS and it gets
its own database, processes and IP addresses. It also gets cgroups which governs resources. They make sure that not one container is using all the
resources but it shared all the way across. Each container gets a read write view such a Union File system. These three make up the idea of a container.
Containers assist developers in making software portable. The software looks the same everywhere you deploy and run it. Also developers will not
need to install the app dependencies on user's host.
Once you have a distributed system that consist of different pasts, then the different parts can be hosted in that container.
Docker containers not just an application but

Abstract
Giving security in an appropriated framework requires more than client confirmation with passwords or advanced declarations and secrecy in
information transmission. Circulated model of cloud makes it helpless and inclined to refined dispersed interruption assaults like Distributed Denial of
Service (DDOS) and Cross Site Scripting (XSS). To handle expansive scale system access movement and managerial control of information and
application in cloud, another multi–strung circulated cloud IDS model has been proposed. Our proposed cloud IDS handles huge stream of information
bundles, investigate them and produce reports proficiently by coordinating learning and conduct examination to distinguish interruptions

Essay about Failures in a Distributed System
Failures in a Distributed System Paper Phyllis Lenoir POS/355 November 19, 2012 Asho Rao A distributed system is an application that executes a
collection of protocols to coordinate the actions of multiple processes on a network, where all component work together to perform a single set of
related tasks. A distributed system can be much larger and more powerful given the combined capabilities of the distributed components, than
combinations of stand–alone systems. But it's not easy – for a distributed system to be useful, it must be reliable. This is a difficult goal to achieve
because of the complexity of the interactions between simultaneously running components. A distributed system must have the following
characteristics: *... Show more content on Helpwriting.net ...
Four types of failures that can occur in a distributed system are: * Halting failures: A component simply stops. There is no way to detect the
failure except by timeout: it either stops sending "I'm alive" (heartbeat) messages or fails to respond to requests. Your computer freezing is a
halting failure. * Omission failures: Failure to send/receive messages primarily due to lack of buffering space, which causes a message to be
discarded with no notification to either the sender or receiver. This can happen when routers become overloaded. * Network failures: A network link
breaks. * Timing failures: A temporal property of the system is violated. For example, clocks on different computers which are used to coordinate
processes are not synchronized when a message is delayed longer than a threshold period, etc. www.code.google.com Timing failures– there is
suspicion of a possible failure related to the motherboard. This can be a result of a specific message strongly implicating the motherboard in some
sort of erratic system behavior. It may also be the case that the motherboard probably isn't the problem, but that we want to rule it out as a possible
cause. Since the motherboard is where all the other components meet and connect, a bad motherboard can affect virtually any other part of the PC. For
this reason the motherboard must often be checked to ensure it is working properly, even if it is unlikely to be the cause of whatever is

This coordinates elements supporting high adaptability and multi–occupancy. In addition, distributed computing minimizes the capital consumption.
This methodology is gadget and client area free. As indicated by the not at all like sorts of administrations offered, distributed computing can be
considered to comprise of three layers. IaaS or Infrastructure as a Service (IaaS) is the most minimal layer that gives fundamental base bolster
administration. PaaS – the Platform as a Service (PaaS) layer is the center layer, which offers stage arranged administrations, other than giving the earth
to facilitating client 's applications. SaaS – Software as a Service (SaaS) is the highest layer which includes a complete application offered as
administration on interest. SaaS guarantees that the complete applications are facilitated on the web and clients use them. The installment is being
made on a pay–per–use model. It takes out the need to introduce and run the application on the client 's nearby PC, in this manner mitigating the client

Developing An Advanced Modern Distributed Networking System
Abstract – Developing an advanced modern distributed networking system is very difficult and hard to manage as they operate over different
environments, hence they have little control over the system and the environment in which they execute. The hardware and software resources in these
networks may fail and become malicious unexpectedly. In these scenarios redundancy based reliability techniques can help manage such failures. But
when the network is faced with dynamic and unpredictable resources and also there are chances of hackers and attackers to easily enter the network, in
these situations the system or the network reliability can still fluctuate greatly. In order to tackle these kind of situations we need to come up with some
kind... Show more content on Helpwriting.net ...
Also if there is a desired increase in the system's reliability, then iterative redundancy achieves this reliability by using least resources possible. Iterative
redundancy is also good in handling Byzantine threat model, which is the common threat model in most of the distributed networks. Later in this paper
we formally prove iterative redundancy's self–adaption, efficiency and optimality properties. Then we use discrete event simulation; BIONIC and
XDEVS to evaluate iterative redundancy against the existing redundancy based models. At the end we will be contributing on top of this paper, in
order to eliminate some of the limitations in iterative redundancy and to make this technique much better. We will be seeing that the two assumptions
made in this paper will be contradicting in the real world example. To tackle these limitations, we will be presenting Master–Slave model and also
Hand–shake mechanism to finally, we will be proposing a redundancy based technique known as Physical Redundancy, in which we are using active
replication of the nodes and adding the voters in order to improve the reliability of the network at the node level. With this the error will be ruled out
and the network will act like there was no failure. Keywords: Redundancy, reliability, fault–tolerance, iterative redundancy,

A Byzantine Fault
Introduction
Faults occur in every system which may halt the systems functionality. A fault that presents different symptoms to different observers is called a
Byzantine fault. These Byzantine faults form the reason for the loss of a system service and are called Byzantine failures. A Byzantine failure may
occur due to arbitrary problems like corruption in their local state, production of incorrect outputs or by processing requests incorrectly instead of the
general situations like crashing or stopping. The ability of a system to defend itself from Byzantine failures is called Byzantine fault tolerance which is a
sub–field of fault tolerance.
A reliable computer system is a system that overcomes failures, one such failure is the Byzantine Generals problem. This problem is rare and
generally overlooked by the people who are unfamiliar with the problem. It brings down the entire network if not tackled properly. This problem is
most common in distributed dependable network. This paper aims at explaining the Byzantine Generals problem and providing a possible solution to
that problem.
My motivation to write this topic comes from the wide usage of distributed systems in various fields like particle physics, bioinformatics, weather,
climate, visualization and graphics, economics and finance etc., and the need to protect such systems. Failure of distributed systems leads to huge loss
of resources, time and money. Thus protecting from these kinds of failure is a challenging task

When you store your photographs online rather than on your home machine, or utilization webmail or an interpersonal interaction webpage, you are
utilizing a "distributed computing" administration. In the event that you are an association, and you need to use, for instance, a web invoicing
administration as opposed to redesigning the in–house one you have been utilizing for a long time, that web invoicing administration is a "distributed
computing" administration. Distributed computing alludes to the conveyance of processing assets over the Web. As opposed to keeping information
all alone hard drive or overhauling applications for your needs, you utilize an administration over the Web, at an alternate area, to store your data or
