Wireless Networks and Mobility Model
Networking , Technology & Science / January 21, 2018

In recent years, the deployment and importance of wireless networks has grown rapidly. Mobility plays a key role in this regard, and has driven the development of many new services, such as VoIP and interactive multimedia. Simulations of wireless networks employ several components critical to the accuracy of the simulations, one of the most important being the choice of mobility model, which creates the movement patterns of mobile nodes that forms the varying topology of the network. A typical mobility model first places the mobile nodes in their initial locations and defines the way that the nodes move within the network. Indeed, the mobility model emulates the real user movement through the inclusion of the critical movement factors such as direction, speed, destination, and the movement histories of the same, or similar, users. Overview of Mobility Model The mobility patterns are the key criteria that influence the performance characteristics of the mobile ad hoc networks. The mobility model is designed to describe the movement pattern of mobile users, and how their location, velocity and acceleration change over time. Since mobility patterns may play a significant role in determining the protocol performance, it is desirable for mobility models to emulate the movement…

What is Keystroke Dynamics, Applications and Definition
Technology & Science / January 20, 2018

The increasing use of automated information systems together with our pervasive use of computers has greatly simplified our lives, while making us overwhelmingly dependent on computers and digital networks. Technological achievements over the past decade have resulted in improved network services, particularly in the areas of performance, reliability, and availability, and have significantly reduced operating costs due to the more efficient utilization of these advancements. We argue that the use of keystroke rhythm is a natural choice for computer security. This argument stems from observations that similar neuro-physiological factors that make written signatures unique are also exhibited in a user’s typing pattern. Introduction of Keystroke dynamics Keystroke dynamics or typing dynamics refers to the automated method of identifying or confirming the identity of an individual based on the manner and the rhythm of typing on a keyboard. Keystroke dynamics is a behavioral biometric, this means that the biometric factor is ‘something you do’. These days each household has at least one computer keyboard, making keystroke dynamics the easiest biometric solution to implement in terms of hardware. With keystroke dynamics the biometric template used to identify an individual is based on the typing pattern, the rhythm and the speed of typing on…

Introduction of Context Aware Computing

Context-aware computing promises a smooth interaction between humans and technology but few studies have been conducted with regards to how autonomously an application should perform. Context-aware computing is a style of computing in which situational and environmental information about people, places and things is used to anticipate immediate needs and proactively offer enriched, situation-aware and usable content, functions and experiences. The notion of context is much more widely appreciated today. The term “context-aware computing” is commonly understood by those working in ubiquitous/pervasive computing, where it is felt that context is a key in their efforts to disperse and enmesh computation into our lives. Overview of Context-aware computing Context is a powerful, and longstanding, concept in human-computer interaction. Interaction with computation is by explicit acts of communication (e.g., pointing to a menu item), and the context is implicit (e.g., default settings). Context can be used to interpret explicit acts, making communication much more efficient. Thus, by carefully embedding computing into the context of our lived activities, it can serve us with minimal effort on our part. Communication can be not only effortless, but also naturally fit in with our ongoing activities. A great deal of effort has gone into the field of…

An Introduction of Big Data Analytics
Big Data , Technology & Science / January 18, 2018

In digital world, data are generated from various sources and the fast transition from digital technologies has led to growth of big data. It provides evolutionary breakthroughs in many fields with collection of large datasets A huge repository of terabytes of data is generated each day from modern information systems and digital technologies such as Internet of Things and cloud computing. Analysis of these massive data requires a lot of efforts at multiple levels to extract knowledge for decision making. Therefore Big data analytics examines large amounts of data to uncover hidden patterns, correlations and other insights. With today’s technology, it’s possible to analyze your data and get answers from it almost immediately – an effort that’s slower and less efficient with more traditional business intelligence solutions. Overview of Big Data Analytics The concept of big data has been around for years; most organizations now understand that if they capture all the data that streams into their businesses, they can apply analytics and get important value from it. But even in the 1950s, decades before anyone expressed the term “big data,” businesses were using basic analytics (essentially numbers in a spreadsheet that were manually examined) to uncover insights and trends. Artificial…

How Business Analytics Works

Every business is dynamic in nature and is affected by various external and internal factors. These factors include external market conditions, competitors, internal restructuring and re-alignment, operational optimization and paradigm shifts in the business itself. New regulations and restrictions, in combination with the above factors, contribute to the constant evolutionary nature of compelling, business-critical information; the kind of information that an organization needs to sustain and thrive. Business Intelligence (“BI”) is broad term that encapsulates the process of gathering information pertaining to a business and the market. What is Business Analytics? Business intelligence (BI) has two basic different meanings related to the use of the term intelligence. The primary, less frequently, is the human intelligence capacity applied in business affairs/activities. Intelligence of Business is a new field of the investigation of the application of human cognitive faculties and artificial intelligence technologies to the management and decision support in different business problems. The second relates to the intelligence as information valued for its currency and relevance. It is expert information, knowledge and technologies efficient in the management of organizational and individual business. Therefore, in this sense, business intelligence is a broad category of applications and technologies for gathering, providing access to,…

Voice over Long Term Evolution (VoLTE)
Networking , Technology & Science / January 16, 2018

Rapid increase in data traffic over cellular network is necessitating deployment of Long Term Evolution (LTE) in the cellular operator’s networks. While LTE provides efficient data traffic handling and high data rates, it lacks native circuit switched voice capability. Mobile operators have begun migrating to fourth-generation (4G) architectures based on the Long-Term Evolution (LTE) standard, including the Evolved Packet Core (EPC) architecture defined by the 3rd Generation Partnership Project (3GPP). According to a recent report from the Global mobile Supplies Association (GSA), LTE has become the fastest-developing mobile communications systems technology. What is Voice over Long Term Evolution (VoLTE)? The data traffic, in telecom system, is growing at a rapid pace. However, presently for any mobile system to be commercially viable, the ability to carry voice traffic is essential. The existing 2G/3G mobile systems use “Circuit Switching” to carry voice traffic. In Circuit Switching a dedicated, end-to-end, channel or circuit is established to carry the voice traffic for the entire duration of a transmission. On the other hand, in case of IP networks, the voice traffic is carried using IP packets over data connection. For this generally “VoIP” or “VoLTE” solutions are used. For mobile communications service providers (CSPs), Voice…

What is Wireless Intelligent Network (WIN)
Networking , Technology & Science / January 15, 2018

Increasing complexity in telecommunications services requires ever more complex standards, and therefore the need for better means to write them. Today’s wireless subscribers are much more sophisticated telecommunications users than they were five years ago. No longer satisfied with just completing a clear call, today’s subscribers demand innovative ways to use the wireless phone. They want multiple services that allow them to handle or select incoming calls in a variety of ways. Wireless Intelligent network is developed to drive intelligent network capabilities such as service independence, separation of basic switching functions from service and application functions and independence of applications from lower-level communication details into wireless networks. Introduction of Wireless Intelligent Network (WIN) Enhanced services are very important to wireless customers. They have come to expect, for instance, services such as caller ID and voice messaging bundled in the package when they buy and activate a cellular or personal communications service (PCS) phone. Whether prepaid, voice/data messaging, Internet surfing, or location-sensitive billing, enhanced services will become an important differentiator in an already crowded, competitive service-provider market. Enhanced services will also entice potentially new subscribers to sign up for service and will drive up airtime through increased usage of PCS or…
