Answer 1

Application case study with network design diagram:

Network design is based on analysis of the performance and the type of protocol used.the suggested network has the ability to address the common network's drawbacks happening in the reliability, security speed and manageability.

It includes the following topics;

1. IOT:- (Internet of things)

Internet of things tends to be touched as a future technology . Based on the concept and constant development of wireless sensors i.e. network design.

The implementation integrates the networking capabilities of a WSN, a wireless local area network and smartphone device , in order to achieve a monitoring service and tracking mobility of object for the purpose of future internet of things service. Or a way that one will be able to "understand" and monitor an individual movement inside a house.

Index term: IOT , iPhone, smartphone, WSNs, Zigbee .

2.Bluetooth:- In the network design and built a stereo network that streams audio from a Bluetooth-enabled device. And automatically handled playback from the speakers closest to the user . The system is comprised of a hub to which the user's device connect to , and speakers adapters which enable any speaker with a 3.5 mm Audio jack to interface wirelessly to our hub.

Each unit consist of a Bluetooth chip and a microcontroller.the hub broadcast audio to the speaker adapter , which is constantly sending back signal strength data about the user's audio device.

Each of components is powered by lithium aluminum battery and. Charged over USB , with our Bluetooth stereo network.

3. Fog computing:- Fog computing refers to a decentralized computing structure, where resources, including data and application, get placed in logical location between the data source and the cloud; it also is known by the terms fogging and fog networking.

Fog computing can also be deployed for security reasons as it has the ability to segment bandwidth traffic and introduce additional firewalls to a network for higher security .

4. Redundant:- Network redundancy is a process through which additional or alternate instances of network devices , equipment and communication medium are installed within network infrastructure .

It is a method for insuring network availability in case of a network device or path failure and unavailability. As such , it provides a mean of network failover.

5.Resilient and measures of resilience:-

We analyze resilience of weighted network.the purpose of measure resilience network on shock propagation along network path.Networks are the core of modeling many engineering context.mainly in case of infrastructure and communication system.

The Resilience of network which is the property of system , capable of absorbing external shock. Is then of Paramount relevance in the application.this paper deals with the topic by advancing the theoretical praposal of measuring the Resilience of network.

6. Troubleshooting with half split and move method:- ​​​​​​

Basically trouble shooting and problem solving are the same thing. They both related to solving problem.the word " Trouble shoot " tends to be used more for repair of well defined system or in human dispute.

The generality in definition has led to some interesting choices and mischoices in hiring of consultant and expert trainers, as well as the adoption of methodology to "solve problem" .

The good choices have spawned success , while the mischoices have failed and been lebeled "program of the month".
