Robust and Secure Voice Transmission over Wireless Mobile Ad Hoc Network

With the growth of the Internet services, Voice over IP (VoIP) has been playing a key role in cutting the costs of telephone calls. It can be seen that since demand of VoIP over wireless network is growing, use of VoIP over Mobile Ad Hoc Network (MANET) is expected to grow as well. We have identified many challenging issues to ensure robust and secure voice communication over MANET. In this paper, we depict a framework for robust and secure voice transmission over multipath MANET. We propose robust multipath routing protocol along with efficient traffic allocation approach as well as end-to-end security mechanisms for both routing and real-time traffic transfer. We conduct series of simulations to evaluate such a framework through different performance metrics.
