The Internet of Things- Free-Samples for Students-Myassignment

Questions: 1.What does the statement "the best interface for a system is no User Interface"? 2.Compare the bandwidth, distance, interference rating, cost and security of a) twisted pair cable, b) coaxial cable and 3) fibre optic cable. 3.The three common ways to obtain information from IoT devices are sensors, RFID and Video tracking. Compare the three technologies by addressing the advantages, disadvantages, key requirements for the things. 4.Discuss the Issues associated with security and privacy in the context of the Internet of Things. 5.An IoT Water level monitoring application requires updates from a sensor periodically, using the command/response paradigm. 3.Describe Nielson's Law. How does it relate to Moore's Law? What are the implications for the Internet of Thing? Answers: 1This is considered to the smarter and the simple system which is able to handle the useful setups that makes the life easy. Along with this, there is an easy elimination of the interface to embrace the different natural processes and work for the proper betterment of the messaging for the better user experience. The UI is set with the constant stream of new interface which is filled with the different menus and the buttons. This explains about the conversational apps and how the UI interaction is able to work with the advancement in the technology with the increased invisible apps that are set with the UI for the computer input. The designer need to manage the applications of the bank and then work towards the better brain computer interaction. (Cui, 2016). The examples related to this are the driving approaching the car, the taking of the smartphone out of the wallet, turning the mobile phone on, sliding the phone to unlock, switch off and sits in the car. The other example of the same is the shopper enters the shop, use his mobile phone and then checks it, buy grocery and get billing. There are different possibility where a person can reach to her destination. Hence, the no user interface is best. 2. Twisted coaxial Fibre Bandwidth 0-3.5 KHz 0 to 500 MHz 186 to 370 Thz Cost Medium More than twisted High Security Low Low High Interference rating Medium Medium Low distance 2km 1 to 9 km 40km 3.Sensors: Advantages This comes with the network benefits which are for the individual, society and the other business applications. The sensors are for the home security and for the controlling which could be through the remote manner or through the easy usage of the applications. The sensors are for the monitoring where there is a use of the wireless monitoring for the network. Disadvantages It is managed by the different technology where there are different vendors who are in it. The implementation of IoT is considered to be a major loss of the job for the people with everything on the applications. (Rifkin, 2014). The issues of the multiple technologies which leads to the consumption of time in the complex systems. with this, there is a possibility that IoT service provider have to pay hre for the hiring and for retention of employees. Key requirements The requirements are based on working over the IoT systems which includes the costs for the testing of device manufacturers and the network service providers. Applications This is needed in the cameras, security alarm or the door locks. RFID Advantages The RFID makes use of the electromagnetic fields to identify and track the tags which are attached to the objects. The passive tags are contained with the collect energy with interrogating the radio waves. The active tags are handling the local power source with the RFID reader to interrogate and handle the operations at the hundreds of meters. The barcodes are for the embedded subject with the tracked object. (Atzori et al., 2014). Disadvantages The issues are related to the fact that RFID could be used by the multiple people for the receiving and the transmission of the data which could lead to the interference and the radiation exposure as well. Key requirements The RFID is set for the cash, clothing and the possession with the implantations in animal and people. The concern is about the privacy and security set for handling the RFID cards, labels and the other form factors. Applications RFID tags include the automobile during production which could be used to track with the progress set under the assembly line. Video Tracking Advantages It is for the tracking of the objects with the use of camera. The variety of uses which includes eh security and surveillance, interaction, video communication and compression, augmented reality and traffic control. Disadvantages The disadvantage is about the objects that are relative to the frame rate with the tracking of the object change orientation over the time. Key requirements The requirements are for the checking of the target representation and the localization, using the blob tracking which is for the identification of the human movement. (Patton et al., 2014). Applications For the 3D objects and for the affined transformation. The video compression is also for the macroblocks. 4.The issues are related to the security problems where the focus is on the communication and the working over the users to handle the quality of the peoples live. The storage, processing phase with the processing is based on the different activities where the future behavior of the people is mapped to handle the data encryption or the access control mechanism. The privacy and security issues are set with the widespread usage with the wireless sensors that involve the access and the availability, accuracy and confidentiality problems. The issues are also related with the transmission, storage and the processing phase. The tracking of the lifestyle, activities, with the accessibility of the third and the unauthorized person. The issue is related to the threat and the attacker models 5.Request Trigger time = 1s Round trip propagation delay = 12 ms Request processing time = 3ms Application transportation time = 2ms Total time: 1s+12ms+3ms+2m+2ms = 1.019 s If the publish/subscribe communication model will be used, the request time of 1 sec will be removed, request processing time will be removed and the round-trip time will become half due to only one way transportation of data and hence, the total time will be: Time = 6ms+2ms = 8ms 6.Nielsen law of internet bandwidth includes the higher end connection speed which growth with the year. Hence, for this, there is a connection of the constant dot which works for the telecom companies. The users are found to be reluctant to spend the money on the bandwidth where the user base is tending to get broad. Here, there are low end users with the high end working for the average shift that is low. The designing applications are important for the computation with the web designs set for the optimized usability and for the availability of the speeds. (Patton et al., 2014). With this, there has been observation on Moores law about the computer processing which doubles every 18 months. There are high end users for the bandwidth growth in 50% with the 10% less than the Moore law. For the IoT, there is a need for the telecom companies to work with the time to update and handle the reluctance to spend the money on the bandwidth. References Atzori, L., Iera, A., Morabito, G.
