Architecture and emulator in ad hoc network for providing P2P type SIP_VoIP services

Provision of SIP-based, connection-oriented services can give rise to a variety of applications in an ad hoc network. Although there have been many studies on ad hoc networks, they have not sufficiently focused on the evaluation of SIP services. This paper proposes a MANET emulator architecture and local multipath routing suitable for SIP services. We have built a SIP_MANET emulator and confirmed the correct operation of a SIP_VoIP call. We confirmed that the proposed routing method has a high path retaining probability.
