Abstract
Abstract: In this paper, we address the problem of voice multicasting in ad hoc wireless networks. The unique characteristics of voice traffic (viz. small packet size, high packet rate, and soft realtime nature) make conventional multicasting protocols perform quite poorly, hence warranting application-centric approaches in order to increase robustness to packet losses and lower the overhead due to high packet rate. By exploiting the path diversity and the error resilience properties of multiple description coding (MDC), we propose a robust ...
