Abstract

The purpose of this paper is to design and implement a telephony program that uses Wi-Fi using Peer-to-Peer communication between mobile phones without any cost. The system will allow users to search for other individuals within the Wi-Fi range and to establish free P2P voice connections, or to establish virtual connection through Access Points (AP) in case of unavailability of the mobile device in the same Wi-Fi. In addition, we are using a novel algorithm to tackle the previous fundamental problem of designing Ad hoc and p2p telephony using Wi-Fi which will be independent of the service provider database. This algorithm always gives unique IP address for corresponding mobile number and vice versa. Thus, providing real feel of telecommunication without changing the behavior of user interface with the traditional mobile services. Further we are using SIP (Session Initiation Protocol) to create, modify and terminate multimedia sessions between two participants. This proposed paper will allow one call per connection, and no call waiting or conference calls. It can be further extended to support SMS (Short Message Service) as well as MMS using the same novel algorithm.
