Voice-based protocols for mobile ad hoc networks: Challenges, design principles, and implementations

Abstract

With the increasingly popularity of mobile devices (e.g. iPhones and iPads), Mobile Ad hoc Networks (MANETs) has emerged as one of the topical research areas in recent years. The special characteristics of MANETs (i.e. infrastructure-less and self-configuring) provide a flexible way of connecting mobile devices. Such implementation can provide the means of communications where telecommunication infrastructure is inattentive (Out-of-range, out of credit). Due to the inherent characteristics of MANETs (e.g. self-configuration of IP addresses), implementing Voice over IP (VoIP) services over MANETs remains an ongoing research challenge. In this paper, we highpoint the challenges of implementing VoIP, recommend design principles for such implementation and discuss some implementations. This research is based on an expert advice with over 15 years' experience in the area of computer network and around 10 years on intensive research in the area of adapting voice-based protocol for MANETs.
