Abstract: With the ever fast paced evolution of technology, communication will be indispensable with the Internet. Wi-Fi Direct provides the capability of communication between devices without the use of any Internet connection. With such a capability, Wi-Fi Direct could be used for communication whenever an Internet connection is unavailable. Hence, this report covers the different approaches taken to implement a reconnection mechanism for an existing Wi-Fi Direct Chat Android Application, named WiFiChat. This reconnection mechanism should activate when an unnatural disconnection occurs, this could happen when the devices are considerably distant from each other. The functionality and limitations of WiFiChat are listed. A general introduction to the Wi-Fi Direct framework and Android’s Wi-Fi P2P API is also given. The implementation section provides the reasons on why the original code is unable to support reconnection, so as to understand the logic behind the approaches taken. The changes are also described in detail with supporting reasons on why a certain action is incapable of reconnection. Unfortunately, the changes were inadequate to implement the reconnection mechanism. A conclusion drawn from this would be the formation of persistent groups and how it retains group information despite removing them.
