1.2 BROADBAND DEVELOPMENTS As large portion of the global communications infrastructure is represented by wireless technology, it is vital to understand overall broadband trends and the role between wireless and wire line communication technologies. Several times both wire line and wireless technologies competed with each other, but generally, they are complementary to each other. For the most part, core infrastructure and backhaul transport for wireless networks are based on wire line…

Comparison between Li-Fi and Wi-Fi This section is mainly dedicated for 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…

The two source nodes, 1 and 2, have messages A and B that need to be transmitted to the two destination/sink nodes, 5 and 6, which need both A and B to be delivered. Each edge in this network can only carry a single value. If nodes could only route/retransmit, then the central link would only be able to carry message A or message B, but not both of them at the same time. Assuming we sent message A through the center, then node 5 would receive message A twice and would never receive message B.…

CHAPTER 1 1. INTRODUCTION 1.1 WIRELESS SENSOR NETWORK (WSN): Wi-Fi sensor networks (WSN), once in a while called wireless tool and actuator networks (WSAN), are spatially disbursed autonomous sensors to monitor bodily or environmental situations, which include temperature, sound, pressure, and so forth. and to cooperatively pass their expertise through the network to a major location. The extra brand new networks are bi-directional, additionally sanctioning control of device activity. The…

compares various wireless networking technologies which can be used for industrial automation and sensing. Among all these technologies, special emphasis is given on Zigbee. Zigbee is a technology known for its low power consumption, low data rates, and self-healing reliable networks, which makes it very efficient for industrial applications. The layer by layer protocol stack architecture of Zigbee illustrates these advantageous features. Zigbee is used for automation and networking purposes in…

Intelligent Transportation Systems. 6. Social network as big data Social network is the collection huge datasets which comes from distinct sources. The speedy development of the big data on social network lead to a revolutionary change in user’s life and on the world-wide business. Security is also a main issue as whole the communication is through network which allow intruders to take advantage of the data [1]. As the complexity and diversity of the big data of social network is very high…

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…

Technology Framework Design In this section, we combine the user domain needs described in Part 1 of this proposal, the physical framework requirements described in Part 2, and the technology selections described in Part 3 to create the final Digital Edge Manufacturing network infrastructure proposal. Choosing the Cabling Used in the Network We considered infrastructure costs, speed, and reliability for cabling and adaptors. Our network employed hybrid type of network sine we use Ethernet cable,…

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…

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.…
