As we can see the delay dropped significantly when using PCF. However, using fragmentation resulted in different effect in DCF and PCF. In DCF using fragmentation increased the delay as the collisions increased while fragmentation decreased the delay when used with PCF. Using fragmentation in DCF did not affect the load much and it remains…

Topology has its own cable that connects to a central hub or switch, multiplier repeater, or even a Molestation Access Unit. Data passes through the hub to reach other devices on the network. A hub, switch, or computer acts as a router to transmit messages this is in its simplest form. Star reduces the chance…

X. 25 is packet switched wide area network(WAN) common interface protocol between public data networks. It is a packet network access. It is used for establishing connections and and exchanging data as well as control information between network devices. It is mainly used for network terminal operation in packet mode. 3 types of X. 25…

A computer is a piece of equipment that is used by people to carry out tasks and process. A computer is connected to a network if that computer needs to communicate to another computer on the same network. Computers range in size and processing level. A computer is needed in any wireless network. Price varies…

A computer network within a small geographical area such as a home, school, computer laboratory, office building or group of buildings. A LAN is composed of interconnected workstations and personal computers which are each capable of accessing and sharing data and devices, such as printers, scanners and data storage devices, anywhere on the LAN. LANs…

I. Introduction People who live in the past can only communicate through the way of Telegrams, Letters and Telephone Calls. But with the birth of modern Technologies, wireless mobile phone and computers were invented. Then, social networking begins. With this study, there are many questions that we have to consider such as: What exactly is…

Over the past couple of years, social networks have become a part of the lives of the people that use them. People are indiscriminately creating their profiles on social networks, representing themselves in various manners. Through publishing personal information, the users accept the risk of its influence on them – regardless of whether it is…

Introduction The success of wireless and mobile communications in the 21st century has resulted in a large variety of wireless technologies, including second and third-generation cellular, satellite, Wi-Fi, and Bluetooth. Heterogeneous wireless networks combine various wireless networks to provide universal wireless access. Leading wireless companies in some countries operate networks with multiple technologies, such as…

With the advent of new technology, accessing information from around the world has become exceptionally convenient through a few clicks or taps on a glass screen. In a matter of seconds (subject to internet speed), we can acquire knowledge about any subject. Among the numerous advantages offered by technology, social networks have emerged as an…

Abstract In telecommunication systems, a generic access network (GAN) is used by cellular device users to connect and interact with other types of communication devices. GAN protocols primarily evolved for wireless communication systems, allowing mobile phones to perform functions seamlessly between wireless local area networks (WLANs) and wide area networks (WANs) without interrupting the communication…
