Wireless networking

1) Eavesdropping: It can be defined as secretly listening to the private conversation of others without their consent. Here an attacker can choose to passively eavesdrop on the network communication and steal the data. Through passive eavesdropping attackers apparently eliminate their presence in the network and make such attacks difficult to detect. The goal of such an attack is to violate the confidentiality of the communications by intercepting the network and sniffing or listening to…

BLUETOOTH TECHNOLOGY Introduction As with time, our need becomes our necessity. And it is said that, Necessity is father of all Invention. With time we need wireless technology that can replace cables such as Wi-Fi, Bluetooth. Bluetooth is also cable replacement technology that can connect different computer devices with a short-range wireless radio connection. It has wide areas of applications. Some of it’s features is • Low Complex Architechture, • Power Consumption is low • Less Price •…

The interviewee, named Jay Shen, is a software engineer with more than 2-year experiences of developing software application in Amazon.com, Inc. In his viewpoint, a successful software engineer should have learning passion, good communication and creativity. First, Jay mentions that the learning ability is obligatory for a successful software engineer because today is an age in which the technology is growing with a high speed. New algorithms, improved methods are introduced every day.…

technology for networking, it is crucial to understand the limit of certain wireless protocols and how it works in different situations. The most recent Wi-Fi protocol that this report will focus on is, 802.11ac, also known to be the next generation for wireless networks to be equipped with new technologies that could provide faster speeds, capacity, and range. The predecessor, 802.11n, wireless protocol had lower limitation of its full potential to keep the ever growing need of today’s…

characteristics of the wireless communication channel. The simplest model is the protocol model in which two nodes can communicate with each other iff they locate in each other’s communication range Rc. Further, in order to capture other disruptive physical characteristics of the wireless channel (e.g., the multiple path fading, and the interference, etc.) rather than only the diminishing effect of the transmission distance, the authors in [Gupta and Kumar 2000] modeled wireless channels…

frequency spectrum resource is utilized. The efficient use of spectrum is analyzed in terms of coverage area, capacity and reuse distance. OFDMA is a very potential multiple access technique, which will be the key technique for the next generation of wireless communications (4G). In this paper the QoS parameters of OFDMA i.e. spectral efficiency [Erlangs/MHz/m2], system capacity is estimated and also compared with the WCDMA. The other important parameters…

We are aiming to develop a device which is useful for both deaf and dump. We introduce a new device “SILENCE BREAKER”. It consist of a Camera, Micro Projector, Mobile computing device and a bluetooth headset. The synchronized action of all these components helps the dump and deaf for proper communication. The Silence Breaker recognizes the gestures of the dump and generates voice signal corresponding to it. In the case of deaf, the device captures the oral sounds and converts to gestures which…

with friends or families. Also, a type of technology that is used frequently is the Internet. The Internet allows people to connect with people and can gain facts that are essential for people to live. Nurse uses technology such as the Internet and wireless devices to communicate in their field. Also, it makes nurses life’s easier than tracking down a colleague to know what to do if something terrible happens such as someone falling of the bed. Besides making the nurses life easier, the…

User connectivity will be controlled and authenticated through active directory. User devices will require and object to be created in active directory which will be used to authenticate the device using 802.1x. When a user device is connected to the network it will initially communicate on a VLAN will only be allowed to communicate with active directory. Then once the device has been authenticated it will place the device on the appropriate VLAN that it will operate on. Any device that has not…
