Figure 1.1: Shows the evolution of internet and internet of things’. The concept of Internet of things(loT) was introduced by the growth of the widel used global network known as the internet along with the deployment of ubiquitou computing and mobiles in smart objects which brings new opportunities for the creatio1 of innovative solutions to various aspects of life. The concept of Internet of things(IoT creates a network of objects that can communicate, interact and cooperate together t reach a common goal [1]. IoT devices can enhance our daily lives, as each device stop acting as a single device and become part of an entire full connected system. Thi provides us with the resulting data to be analyzed for better decision making, trackin: our businesses and monitoring our properties while we are far away from them [3].

Figure 1.2: Shows different applications of internet of things in all aspects of life?. As the paradigm of IoT is growing, it is stepping into every aspect of our lives. This leads to an easier life through wider range of applications, such as electronic health care solutions [2] and Smart city concept. The concept of Smart city aims to making a better use of resources, increasing services quality offered to the citizens, and reducing costs of the public administrations [10]. Another application is home automation which is the main focus of this project.

Figure 3.1: Illustrates the publish/subscribe model provided by PubNubt. The next challenge, after finding a way to connect different devices together and to the internet was actually controlling them over the internet through a web/mobile appli- cation built using Ionic Framework. Different ways and services were explored including setting-up port forwarding on the router. Setting-up port forwarding will change the con- figuration of the router and expose one port of the private Local Area Network(LAN) tc the public, which is considered a security vulnerability that has to be managed carefully. Some of the services that were explored and considered to allow the communication of the web/mobile application with the Raspberry Pi connecting different devices are Weaved, Pusher and AWS Mobile Hub. However, the need of real-time interaction and PubNub’s publish/subscribe model, it was chosen as the most adequate solution.

Figure 3.4: Shows the top and front views of the model design. An essential part of the project was designing a model for simulation, testing and analyzing results. AutoCad was used in designing the separate parts of the home model. The design was given as an input to a laser cut machine, that cut cardboard to the different parts of the design. After that, the model was assembled to form the room model provided in the below figures.

Figure 3.7: Shows the car model components’. Another part of the project was the surveillance car. It was modeled by a four wheel drive (4WD) car using four DC motors and chassis made of acrylic material. The car motors were connected to two H-Bridges and to a Raspberry Pi to control it over the internet.

Figure 3.10: Shows an image of the Raspberry Pi Model B+° The Raspberry Pi is a low priced, credit card sized computer. It can be connecte to a computer monitor or a television through HDMI cable and HDMI port found in tl Raspberry Pit. It has four USB ports, allowing the connection of different peripherals 1 it such as keyboard, mouse, memory stick or Wi-Fi dongle, that allows its connection 1 wireless internet. As any computer, the Raspberry Pi needs an Operating System(O% to run on it, to allow the interaction between it and the user. Different OS choices th: can run on the Raspberry Pi are available such as Raspbian, Linux and a Windows | special version for the Raspberry Pi. The OS is downloaded to a micro SD card ar mounted to the Raspberry Pi’s SD memory reader. It also has Ethernet port that allov its connection to the internet through Ethernet cable from a router.

A 180 degrees servo motor, acting as the door lock of the modeled room, was connect o the Raspberry Pi through the GPIO pins. It was glued to the model’s door along wi . glued cardboard tip to lengthen the servo’s horn. A ”Lock” tab was created in t pplication which has a button that toggles between ”LOCK” and “UNLOCK” whi licked. The default value of the button shows the action that will be taken by t ervo lock, changing its angle, when the button is pressed. If the button shows the val UNLOCK”, this means that the servo motor will be adjusted to 0 degree, unlocking t: loor. The button’s value toggles to ” LOCK”, When the button is clicked, sending a JSC tring holding a value of 0 for ”lock” attribute, {’lock’:0}, to the channel the applicati: ublishes to and the ” publish key” provided by PubNub. The JSON string received | his channel is then sent to the Raspberry Pi, which receives the JSON string, checki he ”lock” attribute value and sets the servo motor’s angle to 0 degrees, unlocking t: loor. Figure 4.1: Shows the servo door lock.
