Abstract :
Voice over Internet Protocol (VoIP) service has been a very popular and important application over the Internet. Wireless VoIP also becomes more and more popular due to its features of low cost and convenience. Recently, wireless mesh network has been considered as a good solution for VoIP services since it is easy to deploy and provides a larger area coverage. However, the security and performance are the main challenges. In this work, we focus on the security issues and present a new protocol for securing the voice traffic over the wireless mesh network, including the client authentication, intermediate mesh nodes authentication to ensure secure multi-hop communication, voice traffic confidentiality and secure optimal routing selection by using the probing packets.
