1. Abstract: Wireless sensor networks is growing rapidly over the few decades. Due to its flexibility, wireless sensor networks has been in practice in many areas. Among various wireless networks, Mobile Ad hoc networks has been one of the unique network. Unlike other network architectures, MANETs have no central architecture; every node is free to work both as a transmitter and receiver. Every single node can communicate freely with every other node which is in their communication range. Otherwise

Routing Algorithms Routing as we can say is selecting the best path in the network to transfer data from one point to another. And Routing algorithm on a router in computer networks decides on which incoming line a packet should travel and thus creating the routing decision. It depends on various factors like stability, robustness, simplicity, correctness, fairness and optimality. Routing algorithms are based on two classes namely. Adaptive : In this the routing process is adapted based on any

as a consultant by AOC dealership to design a network solution for their new location. The new facility is assumed to be wired with UTP and fiber, with outlets in specific locations. The basic network is to be a LAN that serves desktop computers in the general manager’s office, in the salesmen’s area, and the showroom area; mobile devices (laptops, smartphones, tablets, etc.); and various accessories (printers, etc.). A major component of the network is a file server (for storing the sale contracts

to build a computer network by essentially separating it into two systems, the control plane and the data plane. The separation effectively makes it possible to write a single high level program to control the behavior of an entire network. This allows a network operator to potentially write programs to more easily secure, manage or troubleshoot the networks. SDN has gained tremendous momentum and six of the world 's largest networks are supporting it, Google 's 'B4 ' network being one of them. In

Thinking like a hacker to protect your network Adam Martin American Military University Hacking is among one of the many things that all users have to deal with in technology of the current times. It has been an issue for some time and is only getting worse there are ways to attempt to fight off the attempts that will eventually happen. Some of these methods involve software that is able to be purchased online or in a physical store. Other methods involve software that is able to

Abstract Lot of research has been done on Human Activity Recognition(HAR) in the last decade and HAR is expected to be future technology for e-health systems. Here, I discuss various models built using SAS® Enterprise Miner™ 14.1, on a free public domain dataset containing165,633 observations and 19 attributes and compare each model with another. Data used in this discussion, represents the metrics of accelerometers mounted on waist, left thigh, right arm and right ankle of 4 individuals performing

Introduction Since the 20th century, technology has changed the culture, economy, and social norms of this world. It has become the number-one resource of today 's society. The use of technology has transformed the past resources into useful simple tools. In other words, it has enable the teaching and production of new information and materials through the use of devices such as computers, internet, machines, and Wi-Fi. For the most part, technology has made many effects on this world. On one hand

have been used in telecommunications since the mid-1960s. For a decade or so, they carried the bulk of international telephone calls, which they still do on routes to small and developing countries. In addition, VSAT (very small aperture terminal) networks provide essential communications for large companies, big ships, and disaster relief. But the use of satellites on any wider scale has been ruled out by their traditional disadvantages (high cost, expensive and bulky terminal equipment, and annoying

mobile services for up to 20,000 people by 1981. This breakthrough innovation quickly gained ground and became a priority across the world. Just four years later, Cellnet (Telecom Securicor Cellular Radio Limited) and Vodaphone “launched national networks based on analogue technology and customers [began] using a mobile telephone the size of a brick” (Lacohee, Wakeford and Pearson). A second generation of mobile phones, referred to as 2G, underwent development during the 1980s. During this time,

Television network companies are there? How many African American Television companies are competing with the big named companies who rack in millions or billions of dollars? It is logical to say whomever controls the media, controls the mind. Television is a common form of media . A lot of things that we watch has been carefully hand-picked and crafted for blacks but not by blacks. There are currently no Black owned television networks. The question is; who is feeding our minds? Television network companies
