![advantages of using Android.
Using Android we can access core mobile device functionality.
Easy development since it contains SDK, which provides build, run and debugging
Android applications.
Disadvantages of using Android.
It does not assure security for application as the source code is available.
Android requires internet connection to be active[11].
Bluetooth
Bluetooth is a wireless technology standard for exchanging data over short distances (using
short-wavelength) from fixed and mobile devices, and building personal area networks
(PANs).
Advantages of Bluetooth:
Cheap.
Easy to install.
It makes connecting to different devices convenient.
It is wireless.
It is free to use if the device is installed with it.
Disadvantages of Bluetooth Technology:
It can be hacked into
If installed on a cell phone it is prone to receiving cell phone viruses.
It only allows short range communication between devices.
It can only connect two devices at once.
It can lose connection in certain conditions. [14]

- 3. Abstract The aim of this project is to design and implement a home automation system that controls and organizes various home appliances. The user (i.e. home owner) controls his home appliances using his smart phone. The home automation system processes user direct commands, user preferences and data received from various sensors to control home appliances. The project is implemented in hardware and software components that interact through network connections. The main challenge is to implement the project in an economical way such that it can be easily deployed and used by homeowners. An Arduino microcontroller and a mobile phone with an Android platform running on top of it are the hardware and software used. For the network part, an apache local server is used to make a connection between the microcontroller and the mobile phone and allow data transfer to take place in an efficient matter. Different functions are implemented using this system which includes the following: Manually controlled by smart phone application: 1. Open and close garage door. 2. Switch fan on/off. 3. Switch water tank motor on/off. 4. Switch led on/off

- 12. Conclusion. The project is implemented in hardware and software components that interact through network connections. The main challenge is to implement the project in an economical way such that it can be easily deployed and used by homeowners. The data is collected from sensors by the Arduino. Arduino microcontroller is connected to the LAN with Ethernet shield. The configuration of the Arduino for Ethernet shield contains a static IP address for the shield and the local server. Arduino via the shield sends data every 5 seconds (can be adjusted) to the server via a URL using Get method. Server accepts the data and updates the database in the right columns and through in the same time gets the manual/automatic command with other switch status from the correct columns too. The smartphone reads data from the server using JSON method to get sensor values and display them on screen and updates the switch columns on the database if the user has clicked on them. Limitations and future work. The project has few limitations that as follows: 1. The system is vulnerable to the different types of attacks. 2. Hardware limitation i.e. Arduino UNO have low performance and low number of pins 3. The need of a laptop as local server 4. There must be an internet connection on the router. 5. Low range of connectivity i.e. we can’t connect outside the range of LAN. For future workwe suggest the following upgrades: 1. To add the security mechanisms such as the authentication in the mobile phone and making an access list on the database to prevent any unauthorized access. Data must be sent encrypted every time in a different key through the network to prevent the sniffing and replay attacks. 2. To get feedback from ON/OFF switches. 3. Schedule a plan for electronic devices selected by the user to control children usage for example computers and TV. 4. Schedule a plan for electronic devices selected by the user to control air conditioners and washing machines. 5. Implement fire detection system and turning off the power in case of emergency and notify the user on his smartphone. 6. Alert the user the gas jar emptyor a gas leakage is detected.
