Peer-to-Peer Communication between Android Mobiles

In the current days Voice telephony over mobile is possible considering GSM system which is cost consuming. Wi-Fi technology is a form of telecommunication that allows data and voice transmissions over a wide range of interconnected networks. In this thesis we provides a mechanism for live communication over IP using mobile phones at no cost. The purpose of this research is to design and implement a telephony program that uses WI-FI in p2p (Peer-to-Peer) or WLAN (Wireless Local Area Network) as a means of communication between mobile phones. The system will allow users to establish p2p voice connection through Access Points (AP) and then allow user to make voice conversation, sending SMS (Short Message Service). The current system will only allow for one call per connection, and no call waiting, or conference calls. The group chat application is the number of users connected to the server
