Emre K¨ksal o Ness B. Shroff Atilla Eryılmaz c Copyright by Onur Ozan K¨yl¨ o˘lu o u g 2010 ABSTRACT We are in the midst of wireless revolution, and increasing demand continues for wireless applications. This explosive growth, of wireless communications and services, inevitably renders security into a challenging quality of service constraint that must be accounted for in the network design. The state of the art methods in combating the security threats are usually founded on cryptographic approaches. These techniques typically assume limited computational resources at adversaries, are usually derived from unproven assumptions, and most of the time do not offer a measurable security notion. Information theoretic security, on the other hand, eliminates the aforementioned limitations of the cryptographic techniques at the physical layer of communication systems. In this thesis, we concentrate on both the theoretical and the practical aspects of physical layer security. We first start by analyzing elemental interference networks, in particular, two-user channels with an adversary...

...afternoon everyone, we are Group 9 and our discussion issue is “Where is my motorcycle?” Our motivation is according our experiences that there were many students couldn’t find their motorcycles in car park. And if you don’t lock your motorcycles, your motorcycles may be stolen and you almost can’t get it back. So we want to improve these problems. In order to solve the problems, we use wireless communication technology to locate the car position. On the other hand, connect RFID Tags to help us find your car in car park, send signal through the active tags can quickly know the location of their own motorcycle and speed up the efficiency. For example, there is a car park in Providence University. Students always spent a long time to find the car every day, We can solve this problem. Wireless network is transfer data media with non-entity network. It’s combines with telecommunications network to interconnect between the nodes without cables. The advantages of the wireless network is the high mobility , low construction costs , saving time, and difficult-to-wire. Wireless network are usually used in some areas of wide range , temporary or the region need dynamic Internet.

...relationships in the data. It would be relatively easy to handle, but may cause more time doing data entry for analysis. Using a database would make data entry a lot simpler, but it is unnecessary. If you know Excel, it can do a lot for you. Also, I do not believe an enterprise database would be necessary in this scenario since the information collected would be used internally. None of this information would be used across a company or across organizations. The data would be used to make more informed decisions in regards to this one job. In this instance a decision support system (DSS) would be beneficial. The DSS could analyze the data and develop patterns and trends to make predictions (Kroenke. 2014, Chapter 9). By using these predictions, you could easily choose a shipping company or method based on the equipment, location, distance being shipping or by any other variable that could and should be considered. Scenario 2 Although small, this company is spread out and not in a single location, they would require a WAN. LAN’s are used more for business operating within the same facility that could use a wired connection; whereas a WAN utilizes a wireless connection due to...

...CheckPoint: Dorfman Pacific Rolls Out a New Wireless Warehouse IT/205 CheckPoint: Dorfman Pacific Rolls Out a New Wireless Warehouse The problem facing Dorfman Pacific was an inefficient picking system within their warehouse. This problem caused an increase in total required hours to perform the same tasks costing the organization excessive overtime pay. Solutions could include all of the following examples. The most basic solution with the lowest cost to implement, but also the lowest gain in efficiencies would be to reorganize the warehouse using order history to keep the most frequently ordered products in an easier access location and placing the slower moving product in further off locations. The next solution would be to implement a full paperless system including handheld scanners that wirelessly feed order information to warehouse employees. The most expensive solution would be what is known as an automated warehouse. This would require a small fleet of GPS, radio controlled, and proximity aware robots to perform all picking and packing tasks eliminating the human element. The best solution based on the type of goods used within the warehouse would be the mid-range full paperless system that includes handheld wireless scanners. To implement the solution we will have to choose which hardware and software we will need for the warehouse and also what it will need to interface with throughout the rest of the business. We will need a small area of the warehouse to...
