Abstract:
Ad-hoc Wireless Networks are spotted widely in the present scenarios. They play a vital role in business environments where permanent access to network resources act as key factor. They also provide a perfect solution for the creation of ad-hoc networks during natural calamity. This document is a survey of the voice communication in wireless networks. The properties of AWNs and FEC are discussed, and then the issues related to the implementation of voice communication over the network are analyzed. The main findings of this survey are the during voice packet transmission the network visage high packet loss rate. In this report, we illustrate performance results relative to packetization scheme, coding schemes are discussed. In our study we analyze the service of Layered Coding (LC) and Multiple Description Coding (MD) for supporting error resilient voice communication in ad hoc wireless networks.
