1. The Architecture Of Software Defined Radios Essay
2.1 ARCHITECTURE OF SOFTWARE–DEFINED RADIOS
As Reed (Reed, 2002) and others have stressed out, that the benefits of SDR approach go way
beyond the multimode operations. Other benefits stem from the flexibility that comes with
programmability. For instance, it can simplify design by allowing reuse of a common RF front end
with new designs or modes of operation available through software changes. It also enables
improvements to radio performance and functionality through application of digital signal
processing (DSP) to implement adaptive beamforming, interference mitigation, and numerous other
techniques either proven or in development. As the SDR approach has gained traction, a variety of
hardware and software tools for development and exploration have become available. These tools
are broadly accessible with reasonable cost and ease–of–use enabling new opportunities for
engineering education and research. Examples include National Instruments (NI) universal software
radio peripheral (USRP)/ NI LabVIEW software , the Ettus Research USRP/ GNU's Not Unix
(GNU) Radio, WARP , the Lyrtech SDR Platform and the IMEC SDR Platform. For researchers,
these platforms can provide a starting point for development of prototypes operating on live signals.
Such prototypes can effectively demonstrate the practical viability of an implementation and are a
step toward end deployment.

MVP Framework The MVP is derived from MVC software pattern, Pop and Altar 2014, that is
useful for the structuring of user interfaces. The MVP design pattern separates the view from its
presentation logic to allow each to be distinguished separately Qureshi and Sabir 2014, In MVP, the
view goes on to become an ultra–thin component whose function is just to be able to offer a
presentation to the user. The view captures and deals with the events increase by the user, though
forwarding these directly to the presenter who is aware on the means of treating them. The presenter
then communicates with the model, and coordinates with the view's controls directly so as to present
the data. The limitations of the MVP framework are listed below The pattern is complicated and
may be not really necessary for simple screens. The pattern is one more thing to be learnt for busy

Instead, multiple isolated subsystems, called containers, run on a single control host and access a
single kernel. As shown in Figure 4, containers share the same OS kernel as the host; containers are
usually more efficient than VMs, each of which requires a separate OS instance. A Docker container
wraps up a piece of software in an independent subsystem, complete with file system and everything
it needs to run: code, runtime, system tools, and system libraries – anything that may be installed on
a server. This guarantees that it will always run the same, regardless of the environment in which it
is running. Containers hold the components necessary to run the desired software, such as files,

These are some reason that traditional processes replace agile processes mainly in small and simple
projects. This is happening because of traditional methods' limitations and deficiencies, which
includes a slow adaptation to business requirements changes, and a tendency to go over budget and
as well as behind schedule. The traditional methods also lack in providing improvements in
simplicity, productivity and reliability phenomena's. Despite of these limitations, traditional methods
are widely used by many software developers in projects. Traditional methods are capable to
provide high assurance, predictability, and stability and their nature is structural, straightforward,
and methodological. Agile processes mainly focus on incremental as well as iterative development.
Also, frequent deliveries after each sprints and customer collaboration are key element of Agile.
Agile process has many advantage such as short lifecycle, low bug–rate, high customer satisfaction,
and fast adaptation to changing requirements. Despite the fact that agile process has many

effects are moving through "several business models forcing companies to adapt or be left behind"
(Versace, 2014, p. 1). The expansion of the Internet and technological industry has no boundaries
and caters to all ages. Versace (2014) stated, "several industries that have only just starting
embracing the Internet, and one of them is the gambling and casino industry:" (para. 3). The online
gaming business or iGaming, "has grown into a multi–billion–dollar business, particularly in
Europe," (Versace, 2008).
The following statistics Newzoo.com (2016) reported are:
In 2016, the US games market will be worth $23.6 billion, with 179 million people playing games –
61% of the online population. Almost 60% of US gamers pay for games, spending an average of
$224 a year. Console gaming is by far the biggest segment in the US, with revenues of $11.4 billion

16. Advantages And Disadvantages Of Javascript Framework
Introduction. The last ten years have seen the release of a huge number of JavaScript frameworks.
Designed and developed to aid in the rapid development of websites, web applications and other
online software. Previously, to develop large applications that were secure, fully functional, cross
browser applications would have taken a team of developers, working on bespoke front–end and
backend systems. With the advancement of the web browser, along with the maturing of HTML5,
CSS3, JavaScript and the addition of frameworks the possibilities for complex web applications is
huge. It is now possible to substitute desktop applications with apps running in the browser. With the
addition of web frameworks, developers can worry less about the complexities ... Show more
content on Helpwriting.net ...
One of the biggest disadvantages of using JavaScript frameworks is the learning curve involved with
each different framework. Each has their own way of working and can take time to learn the
nuances of the framework. Another concern is new developers learning the frameworks and not the
JavaScript language. Because of the frameworks making development fairly easy, basic knowledge
of the language can be lost or overlooked. When using a framework a developer is limited to the
core behaviour provided. Its behaviour cannot be modified, so when developing an application a
developer must take into consideration its limitations. Security can be a big issue for JavaScript
frameworks, both positive and negative. Most frameworks are open sourced, so this allows people to
find flaws that could be exploited. People with bad motivations can study the code to figure out how
to attack a product using a certain framework. But on the positive side of things, being open–
sourced also allows a community of developers to find these flaws and eliminate them before they
become a problem. SEO is another concern when using certain frameworks. Because the code is
rendered client side for most frameworks, it is hard for them to be indexed by search

18. Software Define Network And Network Architecture
Abstract Software–Define Network (SDN) has emerged as a very promising network architecture in
recent years. It largely simplifies the network logic and makes the network traffic more controllable
by decoupling data plane and control plane out of the traditional network architecture, and having
centralized controllers to control network switches. The significant difference from the traditional
network architecture is that the network traffic routing is centralized into controllers such that
network switches are only need to perform forwarding, instead of complicated routing protocols.
The centralized controlling scheme of SDN has many novel and important capabilities such as
global view of the network, software–based traffic analysis, and dynamic reconfiguring of network
forwarding rules. The SDN has attracted the interests of many attackers due to the use of centralized
controlling architecture and many security flaws are remained to be addressed yet. Distributed
Denial of Service (DDoS) attack is one of the most frequent network attack that no effective
countermeasure is acknowledged in traditional network. Fortunately, the characteristics of SDN
bring us new chances to effectively against DDoS attacks. In this paper, we are going to discuss the
classifications and characteristics of DDoS, analyze the advantaged capabilities of SDN
architecture, and present a survey of the methods to detect and prevent DDoS attacks using SDN,

Abstract:
With the advent of fast and easy internet access, online shopping has reached a large number of
users today. In order to buy a product online, a user has to resort to multiple sources during the
course of their purchase, in order to gain information about the product and the purchase. In this
project, we build a smart webstore called Shopomatic, designed to simplify the process of purchase
of books over the internet [1]. Shopomatic contains the basic functionality of webstores, designed
for online shopping [2] [3]. These basic features include the categorical listing of products, a
shopping cart [4] containing a list of all the products selected by the user [5] and a checkout utility
[6]. In addition, this webstore exhibits extended connectivity with its users and other related web
services. The users are given an option of receiving email notification for certain events. These
events include successful registration of an account by the customer and successful checking out of
the shopping cart. Shopomatic is also integrated with amazon.com and it is designed to pull reviews
from amazon.com and display it in the user interface of Shopomatic.

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.

set of features satisfying the specific needs of a particular market segment or mission and that are
developed from a common set of core assets in a prescribed way.
Software product lines are emerging as a viable and important development paradigm allowing
companies to realize order–of–magnitude improvements in time to market, cost, productivity,
quality, and other business drivers. Software product line engineering can also enable rapid market
entry and flexible response, and provide a capability for mass customization.
The various product variants can be derived from the basic product family. The purpose is to reduce

38. Computer Architecture : The Terminal Server Architecture
The first famous business applications architecture that was used in the 1950s until 1990 was the
terminal server architecture.
Mainframe architecture:
At the beginning of the application architecture world, we had mainframes that executed all the
applications logic in a centralized manner and the mini computers as terminals that just displayed
the applications screens to the users and captured user's inputs. The main advantage of this
architecture was that deployment was easy to perform. The main disadvantage was that user
interface was very limited, the display was characters based and the user's inputs was limited to a
keyboard.
Client/Server
The terminal server architecture was replaced in the 1990 with the client server architecture. In this
era most of the application logic was moved to the clients and the server was mostly limited to a
database server to exchange data between client and server. One on the main disadvantage of this
architecture was that, you needed to deploy the application on each client and there could be
potential compatibility issues between different clients.
Web App model:
In the early 2000, web application architecture started replacing client/server architecture. Most of
the application logic went back to the server like in the mainframes era. This model solved the

History of REST
Since 1994, the REST architectural style has been used to guide the design and development of the
architecture for the modern Web (Roy T. Fielding, 2000)
When HTTP , Uniform Resource Identifiers (URI), was being developed by the Internet
Engineering Taskforce there was a need for a model to be created of how the WWW should actually
work.
This idealized model of the interactions within a web application, is what was then later referred to
as the Representational State Transfer (REST) architectural style and it became the foundation for
the modern Web architecture, providing the guiding principles by which flaws in the preexisting
architecture could be identified and extensions validated prior to deployment. (Roy T. Fielding., et
al., 2005)
World Wide Web
Initially the web was meant for researchers but around 1993 it became evident that more entities
were likely to use it as usage was starting to spread to campus dorms, clubs houses personal home
pages and later to the institutions and commercial companies.
When individuals started publishing their personal information, on different topics they felt fanatic
about this social network effect started a rapid growth of sites that still goes on to this day.
Commercial interest also was beginning, but it was evident by then that the ability to publish on an
international wide scale would be inevitable to business and related entities.

ABSTRACT
Nowadays, conventional software development methods have gradually been replaced by agile
software development methods. This phenomenon is mainly due to the conventional methods'
shortcomings, including a slow adaptation to rapidly changing requirements, and a tendency to be
over budget and behind schedule. This paper analyzes objectives, strengths, and weaknesses of both
conventional and agile methods. This paper also briefly explains the Unified Process, and the
common elements of the Scrum process. Finally, this paper suggests a new Component Integrated
software development process that combines the Rational Unified Process with the Scrum process to
accommodate the strengths of both methods while suppressing their weaknesses. ... Show more

One system development methodology is not necessarily suitable for use by all projects. Each of the
available methodologies is best suited for specific kinds of projects, based on various technical,
organizational, project and team considerations.
Conventional heavyweight, document–driven software development methods can be characterized
as extensive planning, codified process, reuse, heavy documentation and big design up front. These
are some reason that conventional methods have been replaced by lightweight agile software
development methods mostly in small–scale and relatively simple projects. This phenomenon is
mainly due to the conventional methods' shortcomings, including a slow adaptation to rapidly
changing business requirements, and a tendency to be over budget and behind schedule The
conventional methods also have not able to provide dramatic improvements in productivity,
reliability, and simplicity. Despite the existing shortcomings, the conventional methods are still
widely used in industry, particularly, for large–scale projects. Conventional methods come with their
straightforward, methodical, and structured nature, as well as their capability to provide
predictability, stability, and high assurance. Agile software development methods focus on iterative
and incremental development, customer collaboration, and frequent delivery through a light and fast
development life cycle. There are many positive benefits of the agile approaches.

Introduction As the majority of us know, eBay Inc. is an American based (Headquarters: San Jose,
California) multinational corporation that is dominant on the internet for consumer–to–consumer
product or goods sales. eBay Inc. was founded in the year of 1995 as a personal project by its
founder cum creator, Pierre Omidyar, for his personal goal of assisting his wife's personal hobby of
collecting Pez dispensers. However, in 1998 the company went public, and since then it's President
and CEO has been Meg Whitman ever since. It rose to prominence ever since as the largest online
auction and shopping website for consumers to buy and sell variety of products and goods.
Currently, it is a multi–billion dollar company with its services and operations available and present
in over thirty countries and more. What started as a personal project has gone on to revolutionize the
e–commerce platform and has become a huge success of the dot–com bubble. Throughout its
existence, eBay Inc. has used many different approaches towards its clients, and consumers in order
to make the environment as safe and reliable as possible. This is due to the fact that the e–commerce
platform has its own challenges from time to time, and for a company like eBay Inc. that does what
it does, it is very important to have the uttermost grip and upper hand on their information system

We assume that the public cloud infrastructure provides proper security and data backup solutions
with a Service Level Agreement (SLA) and mechanisms to fairly share its virtual resources among
all its running VMs. The last few years have witnessed the emergence of cloud computing as a
rapid, limitlessly scalable, and cost–efficient alternative in contrast to the in–house data centers. The
IaaS model delegates more control to the customers over the provisioned resources. Hosting Internet
applications in the IaaS environment is an efficient way to start a new and a sustainable business that
expands the IT infrastructure gradually with the business growth.

58. Agile Software Architecture Written By Christine Miyachi
The first article I focused on was Agile Software Architecture written by Christine Miyachi. This
article mainly focused on the concept of agile software development. The concept of agile
development is mainly based on interactions between the software developer and the consumer of
the software. An agile software is something that can be fixed at the last minute due to sudden
changes (Miyachi, 2011). With the ability to change the developing software at any moment in the
process, it is widely believed that the cost to do this would be very high but agile method experts say
that with changing software the cost will actually level out over time (Miyachi, 2011). In order for
this method to work, a development team must accept a process ... Show more content on

The article mainly focused on comparing an evolutionary method to the waterfall method. The
author of the article believed that the waterfall model is very unrealistic and dangerous to use as a
primary development tool for any project (Gilb, 1985). The waterfall method is scheduled for a
single finished date and all planning, design and analysis is done in the very beginning before the
software coding begins (Gilb, 1985). The evolutionary model is based on delivering to a real user,
measuring the added value to the user, and adjusting any issues (Gilb, 1985). A key difference
emphasized in the article was that a system built in the evolutionary model is real and always
changing while the waterfall method is not (Gilb, 1985). The waterfall method is more focused on
what the software will do as compared to the evolutionary method which is more focused on how
well the software will work for the client (Gilb, 1985). Gilb had the opinion that the waterfall
method is no longer a method to follow (Gilb, 1985). Back in 1985, Gilb wanted to show readers
that the evolutionary method was the way software should be developed and that the clients were
more interested in a technology that was perfected for them (Gilb, 1985). As seen in the waterfall
approach, it was very common to have a software developed for a client and the client would not
even know who the developer was (Gilb, 1985). The waterfall method was effective but it is a

Abstract: Software architecture is important because of communication among stakeholders, Design
decisions for understanding software, transferable design of a system. Software architecture
represents a common design of a system that most if not all of the system 's stakeholders can use as
a basis for mutual understanding, negotiation, agreement, and communication. Software architecture
manifests the earliest design decisions about a system, and these early bindings carry weight .It is
also the earliest point at which design decisions governing the system to be built can be analyzed.
Software architecture constitutes a relatively small, intellectually understandable model for how a
system is structured and how its elements work together, and this model is transferable across
systems. There are different types of architectural styles: Distributed architecture, data flow
architecture, implicit asynchronous architecture, data centered architecture, hierarchical architecture
and interaction oriented architecture. This paper compares all the architectural styles and aspects of
comparison are category, styles, advantages, disadvantages, examples.

Summary
The following analysis takes a look at scenario–based usability engineering and software
architecture–based design and the effects, if any, of each given design technique on software quality
attributes as defined by McCall. McCall lists the following attributes as part of a quality software
product: correctness, reliability, efficiency, integrity, usability, maintainability, flexibility, testability,
portability, reusability, and interoperability. These quality attributes will be used as evaluating
factors in determining whether scenario–based usability engineering or software architecture–based
design can help significantly increase the chances of meeting a project's goal with respect to that
quality attribute. This analysis should provide an overarching view as to which design scenario is
best suited for a project given a set of desired quality goals. Below is an introduction to the two
methods being compared.

conceptually created to eliminate conflicts in the development phase. An easy transition and
systematic architecture are essential functions to process an enterprise. The following paper
discusses TOGAF in detail, along with DoDAF and FEAF.
TOGAF is the most common enterprise architecture used globally to enhance business efficiency. It
meticulously consists of business, application, technical, and data architecture. [1] According to the
open group, TOGAF is built from an earlier framework (TAFIM).[2]TAFIM was initially derived
from the United States defense department.
The new conceptual and elaborated version on TAFIM (TOGAF) is easier to comprehend, broader,
developed to reflect a larger population group and flexible to work with other enterprises. Some of
the limitations mentioned in a research design include,
1. Although it's well designed and structured, it does not give a 'concrete guidance' to architects.
2. TOGAF acts more along the lines of a guidance tool, rather than a modeling language or a quality
management system.

I. Introduction
Eclipse is an open source Integrated Development Environment (IDE) for almost every computer
programming language over a dozen platforms (Mac, Linux, Windows, etc.). In fact, it is one of the
most popular IDEs nowadays for multiple programming languages, especially Java. Back in 2001,
Eclipse 1.0 came out as a framework, a flexible architecture that served as the building tool for
developers, providing a variety of accessible toolkits, private or public, to ease to process of
programming. Over the course of time, Eclipse takes in developers' feedbacks and enhances its
accessibility and usability, releasing new versions with more functionality (i.e. Java Development
Tools, Plug–in Development Environment, Rich Client Platform, etc.).
One of the core ideas behind Eclipse is to allow users (in this case developers) to write and share
modules (i.e. toolkits), different from the previous IDEs that hides their individual building classes.
For example, the pioneer Plug–in Development Environment (PDE) for Eclipse was designed
specifically for this purpose, allowing developers to build and test their own plugins that would later
benefit the performance of Eclipse. Eclipse provide an environment that individual users can
manipulate the framework to facilitate their daily work. Like most of the open source software,

Architecture gives the subtle element outline of a system. It is utilized to arrange all the system

dependent upon the complete working meanings of the conventions. The structural engineering is
emphasized in a circulated processing environment and its unpredictability can't be comprehended
