A New Distributed Application and Network Layer Protocol for VoIP in Mobile Ad Hoc Networks

Abstract

Mobile Ad-hoc Networks (MANETs) are a kind of Wireless ad hoc network that usually has a routable networking environment on top of a Link Layer ad hoc network. The main aim of the project is to propose a new protocol for Voice over IP (VoIP) transmissions in wireless ad-hoc networks. Each device in a MANET is free to move independently in any direction, and will therefore change its links to other devices frequently. Each must forward traffic unrelated to its own use, and therefore be a router. The primary challenge in building a MANET is equipping each device to continuously maintain the information required to properly route traffic. Such networks may operate by themselves. They may contain one or multiple and different transceivers between nodes. This results in a highly dynamic, autonomous topology. VoIP over MANETs is a challenging issue due to the intrinsic distributed nature of the existing peer-to-peer paradigm. This paper proposes a new protocol, capable of ensuring a Quality of Service level for VoIP calls over a MANET and to manage calls in the system. Voice over IP(VoIP) is a methodology and group of technologies for the delivery of voice communication and multimedia sessions over internet protocol networks.
