WOICE: A decentralized system for ubiquitous VoIP services

Abstract

We propose WOICE (Wireless vOICE), a fully distributed architecture capable of supporting and offering ubiquitous voice services over wireless IP-based data networks. Existing WiFi infrastructure - deployed by enterprises or even individuals - will be supplemented with software modules based on open standards in order to support VoIP. Furthermore, a new breed of VoIP providers by aggregating these currently isolated access networks will be able to offer alternative and advanced services to reachable end-users. These services would in certain cases completely bypass traditional telephony and cellular providers and in others smoothly cooperate with them. We will describe the overall architecture and the necessary modules that should be in place for realizating a system that creates a marketplace for communication services. © 2009 Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering.
