This document describes an Android-based wireless PC controller. It uses a client-server architecture with the Android mobile as the client and PC/laptop as the server. The Android app establishes a WiFi connection with the PC and allows the user to control applications on the PC remotely from their phone through sockets and interprocess communication. Algorithms and strategies like socket programming and WiFi technology are used to enable two-way communication and data transfer between the mobile and PC processes. The system provides a graphical user interface on the Android app to select PC applications to control.

- 3. Introduction The Smartphone applications can transfer commands to PC using the device communication mechanisms such as Bluetooth and Wi-Fi. That way, the person can interact with electronic devices using a Smartphone. With use of this android application, one can control all the personal computer applications. Once established a connection between an android mobile and PC using Wi-Fi then one can control the different applications.
- 5. System Architecture In this system there is a client-server architecture. In which android mobile phone is a client and PC/Laptop is a server. Client sends request to the server for connection establishment via wireless communication (Wi-Fi). Connection is established using handshaking. After connection establishment ports are assigned and sockets are established at both ends for communication.

- 8. InterProcess Communication InterProcess Communication (IPC) is a set of methods for the exchange of data among multiple threads in one or more processes. Processes may be running on one or more computers connected by a network. IPC methods are divided into methods for message passing, synchronization, shared memory, and remote procedure calls (RPC). There are several reasons for providing an environment that allows process cooperation: Information sharing Computational speedup Modularity Convenience Privilege separation
- 9. Socket Programming A socket is a bidirectional communication device that can be used to communicate with another process on the same machine or with a process running on other machines. Sockets are the only InterProcess Communication that permit communication between processes on different devices such as here in this project the devices are laptop and android mobile. Normally, a server runs on a specific computer and has a socket that is bound to a specific port number
- 10. Wi-Fi Technology & Prerequisites To turn ON Wi-Fi on android device WifiManager provides the primary API for managing all aspects of Wi-Fi connectivity. A programmer can get WifiManager instance through Context.getSystemService(Context.WIFI_SERVICE). WifiManager is used to find the currently active Wi-Fi network and change the Wi- Fi state. Android application must be installed on your android mobile (version 2.2 and above) and the Java application on your laptop respectively.
- 11. Algorithm 1) Start. 2) Request will be sent from android mobile to laptop for connection establishment via wireless communication. 3) Ports are assigned and sockets are established at both the devices for communication and from laptop the acknowledgement message in sent back to android mobile. (Connection Successful) 4) Mobile will send request for controlling any of the provided application, then the request of data transfer is sent by mobile to the laptop. (Socket programming handles this connection for transferring data). 5) Now, the Java application which is installed on laptop responds to requested process by android. (Here, IPC is used for communication between process of laptop and process of android mobile). 6) Mouse controls in windows registry and other processes previously running on laptop (Task Manager) are paused temporarily for few seconds. 7) Lastly, after serving all the interrupts, processes stored in windows registry and task manager will be resumed. 8) Steps 4 to 6 are repeated according to users requirements. 9) Stop.
- 15. Conclusion This proposes a system which will control the various applications of targeted PC using android Smartphone. There is no need of external hardware devices. This system includes the study and implementation of different technologies which are currently popular in market. The system is useful for general users as well as the employees of different fields.
