Mobile VoIP : managing , scheduling and refining voice packets to and from mobile phones

Abstract

Voice over IP (VoIP) is rapidly gaining acceptance. VoIP has already become a multi billion dollar industry in the IT world. On the other hand the use of mobile phones in the world has exceeded all estimations. Given these two technologies, we are unfortunate that there is no VoIP support available for mobile phones. The bridge between VoIP and mobile phones is a long way, but an initiative like this paper would surely lay down the roadmap. Mobile phones have several annoying limitations. Limited data transfer rate, processor speed, lack of protocol implementation etc. are the relevant issues for VoIP. This paper addresses the challenges of VoIP and tries to explore ways to overcome those challenges in mobile phones. The language we used for our experiment is JavaME for its simplicity and wide acceptance.
