Wireless networking

Some of the pratical uses of cyber attacks are- fake wireless access points, cookie theft, and file name tricks. Fake wireless access enables hackers to mimic the free wifi of the establishment they are currently in. When users coonect the hacker can then sniff the users computer for unprotected data. With cookies theft hacks gather information…

technology, have contributed to both a need and a means to create user friendly smart home devices. (Smart metering, 2015) Wireless sensor technology and handheld smart devices such as phones and tablets have become the platform on which this new wave of technology has been based. In combination…

1) Linked Cluster Algorithm (LCA) [5], [6], [7]: LCA, was one of the initial clustering algorithms evolved. It was primarily developed for wired sensors, but later applied in wireless sensor networks. In LCA, a unique ID number is allotted to each node and has two means of becoming a cluster head. The first way is that if the node has the greatest ID number in the set including all neighbor nodes and the node itself. The second way is to assume that none of its neighbors are cluster heads,…

Part B: VoIP Computer-to-Computer Voice over Internet Protocol (VoIP) is the process of taking analog signals, such as a human voice, and transmitting them over the Internet as digital data. Computer-to-computer VoIP is usually thought of as the simplest way to use VoIP, as it simply requires a computer with basic peripherals, an internet connection and can easily be used with popular software such as Skype. What devices are involved from transferring Alice’s voice to the sound that Bob receives…

some fixed interval the PC Master sends request to the Wireless sensor node through the sub master for Data collection. The request send by the PC Master is in the form of frames. The frame which is transmitted by PC master will contain both the sub master id & the wireless sensor node id from where the data should be retrieved. The sub master receives the frame is then check for the wireless sensor node id and then it retransmit to the wireless sensor node as it is. If one of the sub masters…

NAME: LETHOLE RELEBOHILE STTUDENT NUMBER: 24570877 MODULE CODE: INYM 316 ASSIGNMENT 2 4/28/2016 1. a) Why circuit switching does not exploit statistical multiplexing Circuit switching deals with keeping some secure bandwidth when the circuit is being configured. The statistical multiplexing means splitting some links among different connections depending on the needs arranged by the connections. Circuits switching is not vigilant on whether single connections offers any other demands…

Congestion: Solutions using topologies We have learned about multiple topologies this year. This includes the bus, ring, star and mesh topologies. But the most notable one for our purpose is the wireless mesh network. A wireless mesh network makes it to the top of the list because it is wireless. Other topologies like the bus, ring and star networks require physical connections to the…

Networking P1: DESCRIBE THE TYPES OF NETWORKS AVAILABLE AND HOW THEY RELATE TO PARTICULAR NETWORK STANDARDS AND PROTOCOLS There are many types of wireless networks available. This includes: WAN, LAN, MAN, PAN, WLAN. Below, I will go into detail about each type that will help you understand exactly what each type of network is and what it consists of. What is WAN? WAN or also known as a Wide Area Network is a network that consists of many Networks that are a part of other LAN networks that swaps…

not foreseeable a few years ago. For instance, the proliferation of mobile computing in health care has been bolstered by the essential features of mobile devices that allow people to share the content with the help of communication networks like wireless signals, as well as synchronize their content. In fact, Heslop, Weeding, Dawson, Fisher and Howard (2010) assert that more than hundred countries across the globe are currently utilizing some form of mobile health care technology. Mobile…
