Streaming media securely over multipath multihop wireless network

Abstract

With the rapid growth and popularity of wireless LANs (WLANs), the development of ubiquitous services is in demand. Mobile Ad hoc Networks (MANETs) are very attractive for many environments, such as home networking, emergency response scenarios etc. However, real-time voice communication is a critical application for many of these network scenarios. In this paper, we put forward a framework for secure audio streaming over multihop wireless network. And we propose an efficient multipath routing for MANET, while using scalable speech coding and selective encryption in secure RTP. With the simulation results, the performance of the proposed scheme is evaluated. © Springer-Verlag Berlin Heidelberg 2007.
