Vertical Handover Abstract: In this era of technology, next generation wireless networks are very popular that allow users to connect to different radio access technologies such as UTMS, WiMax, GSM, etc. In such heterogeneous environment Vertical Handover is executed thus a user can switch among different radio access networks that makes whole process so complex. Vertical Handover algorithms require many parameters such as interference power, QoS, network conditions, terminal capabilities,…

comparing Li-Fi and Wi-Fi considering various aspects. LI-FI is a visible light technology to achieve high speed wireless communication by using visible light to transfer data. It acquired this name due to its similarity to WI-FI which utilizes radio waves for transfer of data. WI-FI is great for extensive wireless coverage in buildings but has severe limitations for high density wireless information coverage in limited space and has radio waves interference issues; While Li-Fi greatly…

high data rate wireless communication, etc. Instead of radio frequency, VLC uses light, to transfer data. The visible light spectrum is unlicensed and 10,000 times larger than the range of radio frequencies. It can be used as an alternate to the existing radio based wireless communication technologies or in hybrid. Moreover, Integrated VLC resolves issue of load balancing in existing wireless…

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…

The use of electronic devices during classes has been a discussed issue for long, because of problems regarding the safety of the wireless connection, the costs of using these kind of devices for learning institutions and the personal use each student does with them. Many researchers argue that technologies used during lectures are only damage for students, because they tend to pass their time on social networks or surfing in Internet rather than follow the lesson. According to Dr. Claire La…

1. INTRODUCTION Figure: Wi-Fi logo Wi-Fi stands for wireless fidelity. Wi-Fi is the wireless network that used to connect the internet without wires. It’s based upon the radio technology. Many computers can be connected to each other through Wi-Fi and we can share files data and many of the other things through Wi-Fi. A Wi-Fi network operated just like a wired network, but without the restriction of wires, it not only enable user to share the data but it also provide easy connection to the…
