Airport management is mandated in handling baggage of the passengers. The current system is
said to have many issues with baggage, they are lots of complaints due to the increasing loss of baggage.
To sort out this problem, this paper will propose an IoT sensor system. First, the paper will give a detailed
design of the IoT system. Second, the paper will give a clear description of all the security aspects of the
IoT system and protection mechanism. Lastly, the paper will simulate the scenario
An outline of the IoT system
Internet of Things (IoT) is a system which has brought up a lot of benefits. The system has
employed the use of sensors which in turn has greatly improved speed and quality of the production
process. To be able to monitor the movement of a baggage, the IoT needs to be integrated with the cloud
platform so as to send a short message to the owner of baggage about the movement of their baggage.
IoT system lets people to attain a deeper automation, integration, and analysis within the system. The
system utilizes emerging and existing technology for robotics, sensing, and networking. Some of the key
features of IoT include connectivity, active management, small device use, and artificial intelligence.
With IoT, an organization is able to increase efficiency other advantages are improved customer
engagement, reduced waste, and enhanced data collection[CITATION Cha17 \l 1033 ].
A design of the IoT system
Hardware platform
To start with IoT hardware has four building blocks which as shown by figure one below
Figure 1:Hardware building blocks[ CITATION Tra17 \l 1033 ]
The first building block which is thing is a set of an asset which that one desire to control. The
thing building block is integrated with a smart device. The second building block is the data acquisition
module, this focuses on converting the physical signal into digital signals which can then be handled by
the computer. This is the hardware part of the IoT system which include all the sensors which are
mandated in acquiring the real-world signals like motion and vibration. For this IoT, monitoring system
include 3 sensors. In addition to this, some of the considerations to make when coming up with this type
of IoT monitoring system are the signals that one need to measure, the number of sensors, how fast one
ought to measure the real-world signals, and the accuracy one need in the measurement[ CITATION
Ala162 \l 1033 ].Third hardware building block as shown by figure one is the data processing module,
this is the CPU part which processes the data. It also performs native analytics. It also stores data and at
the same time performs any other computing operations. When coming up with IoT monitoring system it
is very important to consider the processing power and the amount of local data storage. The last module
is the communication module. This is the last device hardware module which enables communication
with a cloud platform. This module includes ports like a serial (232/485), USB, Modbus. It also include
radio technology for all wireless communications like WiFi, ZigBee, and LoRA.
For this case, the Airport ought to have 802.15.4 mote modules. This is a hardware platform
which will provide a broad portfolio for wireless modules. The reason as to why the gadget is best suited
for this case is that it provides a portfolio for all the wireless modules which enable the organization to
meet the needs of the organization. The sensor board ought to be of Ds1000 which offers both direct
sensing connectivity and all the IoT sensor capabilities. In addition, the organization ought to go for
802.15.14 network infrastructure of type SG1100 which is able to provide gateway services and is able to
deal with the deployment of wireless sensor networks. The processor for this case ought to be Intel X86;
this type of processor is able to handle all the IoT monitoring system commands[ CITATION Abd16 \l
1033 ].
Operating system
IoT operating system ought to perform better within constraints of IoT devices which includes
size, power, the processing capacity, and memory. There are various IoT OS which includes, Ubuntu
Core, Fuchsia OS, Linux based OS, and RIOT. Ubuntu core is a transactional version which made
specifically for IoT devices. Fuchsia OS; this type of IoT OS which is Google based. On the other hand,
RIOT is one of the open source OS which is specialized for all IoT devices.
For this case, this paper will go for Fuchsia type of operating System which is a cross-device
open source OS. It is an OS from Google which is able to run IoT equipment. The OS also has the ability
to run across the various platforms meaning that it cannot only run only on smartphones but it can also
run on tablets, digital monitors, Airport controls, desktops, and notebooks. One of the major reason this
paper has gone for Fuchsia OS is that it is integrated with Google assistant and the Google cloud
environment[ CITATION Jam171 \l 1033 ].
Sensors and actuators
When making a decision on the types of sensors; one of the major considerations is the sensor
signal conditioning. It is either the sensor signal conditioning is integrated with micro-controllers or with
the sensor module package. Another consideration to make is power management. So as to select the best
component four major specifications that this scenario ought to consider which the needed intelligence is
that is required by the sensor node; this ought to dictate either to use a 32 or 16 bit type of processor but
