...Wireless Network xxxxxxxxxxx Strayer University CIS 341 Professor Kevin Jayne My name is xxxxxxx from IT-Vets. Today we will go over the transfer of paper to electronic documentation. We will discuss the use of wireless technology and the risk that are involved. I will also provide ways to make sure we are as secure as we can be. I understand you are moving to electronic documentation due to a federal requirement. In 2004, President George Bush proposed a law that all medical documentation will be electronic by 2014. He stated “by computerizing health records, we can avoid dangerous medical mistakes, reducing cost and improve care.” With this said it is better to act now and get you changed over instead of waiting till the last minute. First thing we will do is go over the plan of attack. With any wireless network the first thing to think about is security. You don’t want just anyone in your network, especially with the sensitive information we will be housing on our network. One of the best ways to do this is to remain invisible. When you drive around with your phone and you have WiFi enable and you pickup signals all over, this is an example of broadcasting your signal. With only authorized users on this network, there is no need to publicly broadcast we have a wireless network. This to me is like a company broadcasting “come see if you can get into my network”. Without the carrot dangling in front of your company you will have less rabbits trying to nibble. Another...

...Wireless Networks & Network Security ISSC 340 Professor Vijay Venkatesh James Lange 08/13/2013 Wireless Networks are somewhat new technology in comparison to the know-how that makes them possible. The knowledge regarding wireless technology goes back about 200 years. One of the first individuals deserving recognition for today’s wireless networks is a scientist, inventor and politician named Benjamin Franklin. In 1747 he had built a model that showed how electricity could move through the air unaided by any type of wiring. In the early 1750’s Mr. Franklin started experimenting with electricity and the rest is history. Franklin was under the belief that lightening was an electrical current. So with the famous kite and key experiment he proved to himself and others that he was right. His fascination with electricity led him to later experiments with an electrical tube given to him by a friend. A second individual that played a part in today’s wireless technology is Hans Christian Oersted. In 1819 he had found that a compass needle had movement if it was presented with electrical current. This relationship between the needle and the electricity is an essential part of electromagnetism. It is said that this discovery by Oersted happened completely by chance. While preparing for one of his lectures he was setting up some of his equipment. The compass and battery were in close proximity to each other and the needle moved from magnetic north whenever the switch to the...

...Paper CNT4514 Wireless Vulnerabilities The world of wireless networks as we all know is one of the most rapidly growing areas in our world today. With the massive amount of data that is going on, “the cloud” the security of all of our data is questioned. As well with so many of our day to day tasks relying on our wireless capabilities it make you wonder how safe is it to rely so heavily on something. We have to ask the questions what are the key vulnerabilities of wireless networks and even just of networks in general. Different types of networks have different levels of safety and it is a good idea to know not only which are safe but the vulnerabilities of said networks to keep our information out of the wrong hands and keep our day to day life moving as smoothly as possible. Unlike wired LANs the wireless LAN users are not restricted to the physical area of a wired system. While this may feel beneficial to the user it is also very beneficial to sniffing and eavesdroppers who are listening to the radio waves that are broadcasted through the air. Intercepting these packets they can pick up messages that may contain sensitive information. Seeing how the range of a wireless LAN can extend beyond the building the eavesdroppers don’t even need to be inside the building. A simple thing you can do is open up your wireless adapter on your computer and see how many open wireless networks are around you. From my house I currently have 4 open wireless networks that I can connect...

...INTRODUCTION Wireless Sensor Networks (WSNs) are distributed embedded systems composed of a large number of low- cost, low-power, multifunctional sensor nodes. The sensor nodes are small in size and communicate wirelessly in short distances. These tiny sensor nodes can perform sensing, data processing and communicating. They are densely deployed in the desired environment. A sensor network consists of multiple detection stations called sensor nodes, each of which is small, lightweight and portable. Every sensor node is equipped with a transducer, microcomputer, transceiver and power source. The transducer generates electrical signals based on sensed physical effects and phenomena. The microcomputer processes and stores the sensor output. The transceiver, which can be hard-wired or wireless, receives commands from a central computer and transmits data to that computer. The power for each sensor node is derived from the electric utility or from a battery. Sensors use a signal of some sort, from the environment and convert it to readable form for purpose of information transfer. Each sensor node has multiple modalities for sensing the environment such as acoustic, seismic, light, temperature, etc. However, each sensor can sense only one modality at a time. The sensor nodes in the target tracking WSN use collaboration with the neighboring nodes. This requires data exchange between sensor nodes over an ad hoc wireless network with no central coordination medium. There...

...WIRE LESS MESS NETWORK WITH HRPU ABSTRACT A Wireless mesh network is a mesh network created through the connection of wireless access points installed at each network user’s locale. Each user is also a provider, forwarding data at next node. The networking infrastructure is decentralized and simplified because each node need only transmit as far as the next node. Wireless mesh networking could allow people living in the remote areas and small businesses operating in rural neighborhoods to connect their networks together for affordable Internet connections. Here we discuss a hybrid routing algorithm for wireless mesh networks. In HRPU, the mesh portal periodically broadcasts a mesh update message, which allows all nodes to have a route towards the mesh portal stored semi permanently in their routing table. Whenever a node has data to be sent to backbone network, it sends the data without any route establishment delay using the route to the mesh portal. In HRPU the mesh portals and mesh points are intelligent which further improves the performance. INTRODUCTION The Beginning: Wireless Mesh Networking (WMN) was developed as a quick way to set-up wireless networks during military operations. Since then it has grown considerably in popularity based on its advantages in both metropolitan and rural applications. WMNs are being applied as Hot Zones, which cover a broad area, such as a downtown city district. By 2010, municipal Wi-Fi networks will cover over 325...
